FIFTH WHEEL AREA INSPECTION The fifth wheel area must be kept clean and free of dirt and foreign materials. This includes the area between the kingpin plate and the body of the trailer where the conveyor chains and flaps travel. Buildup of snow, ice or other foreign materials can cause binding or other serious damage if allowed to remain in this area. Any binding can place excess stress on the front shaft, which can result in any of the following: ? The shaft to bend or break ? The bearings or adjustment mechanisms to be damaged ? The chain to stretch excessively, resulting in premature failure Daily inspect the kingpin and kingpin plate for the following: ? Wear, cracks or other damage ? Damaged or missing parts ? Bent belt return slides (Figure 2); these can be bent during normal operation and must be straightened before use Keep the fifth wheel plate lubricated in accordance with the tractor manufacturer’s recommendations. Figure 2-Belt Return Slides Jun 12 Rev 6 ©2012-2013 Trinity Trailer Mfg., Inc. ADJUSTING AND LUBRICATING THE CONVEYOR SYSTEM CONVEYOR CHAIN The chain must be kept within the two pointers on the chain adjustment gauge, which is located on the roadside of the trailer in front of the suspension area (Figure 3). Adjustment is made by tightening or loosening the hex nuts on the threaded shafts at the front of the trailer (Figure 4). This moves the front shaft bearings forward or rearward and provides the proper amount of tension in the chains. Be certain to tighten the stop nuts on the shafts after making any adjustments. Figure 3-Chain Adjustment Gauge Figure 4-Chain Tensioner Assembly Jun 12 Rev 7 ©2012-2013 Trinity Trailer Mfg., Inc. The conveyor chain must be inspected regularly and lubricated using a high quality oil. Do not use grease. Use Table 1 to determine which grade of lubricant to use based upon the operating temperature. Table 1-Chain Lubricant Guide How often the chains need lubrication is dependent upon the amount of use and the type of product carried. ? Under daily use or in harsh environments, daily inspection is required. Lubricate as needed. ? Under all other uses, weekly inspection should be sufficient. Lubricate as needed. ? If a food-grade lubricant is used, you may need to apply it more often. It is your responsibility to determine how often lubrication is required. WARNING Remember, proper lubrication can extend chain life, reduce down time and save you money. BEARINGS AND SPROCKETS The bearings on the front and rear conveyor shafts must be inspected and lubricated at regular intervals using an NLGI Grade 2 general-purpose grease. As with chain lubrication, the amount of lubrication is dependent upon the amount of use. ? Under daily use, daily inspection is required. Lubricate as needed. ? Under all other uses, weekly inspection should be sufficient. Lubricate as needed. ? Inspect sprockets for excessive wear or damage. WARNING Temperature (Degree °F) Recommended Lubricant -20 to 20 SAE 10 20 to 40 SAE 20 40 to 100 SAE 30 100 to 120 SAE 40 120 to 140 SAE 50 Attempting to lubricate the chains while they are in motion can result in serious bodily injury or death. Stay clear of the chains while they are in motion. Position the chains and completely disable the hydraulic system before doing any maintenance. Attempting to lubricate the bearings while the shaft is rotating can result in serious bodily injury or death. Stay clear of the bearings while they are rotating. Completely disable the hydraulic system before doing any maintenance on the bearings. Jun 12 Rev 8 ©2012-2013 Trinity Trailer Mfg., Inc. PLANETARY GEARBOX When using the planetary gearbox under normal temperature ranges between 0-120 °F, the gearbox is to be half full of SAE 80/90 oil. Use the lower of the two plugs to check the level of the oil. Oil is to be changed after the first 50 hours of operation with subsequent changes every 1000 hours or yearly, whichever comes first. LUBRICATION OF THE DOOR(S) Door hinges and bearings must be lubricated regularly, especially if the trailer has been operated or stored for an extended period of time in a humid or wet environment. Corrosion can lead to the failure of door hinges if they are not maintained properly. As a general rule with the rear doors, as with the entire trailer, “if it moves, lubricate it.” Use a NLGI Grade 2 general-purpose grease on all shafts and grease zerks. The seals on most doors should have silicone grease or spray-on lubricant applied to them once every three months. This will help them last longer and will help them provide a better seal. During cold, damp weather or under heavy use, apply the grease more frequently. CARE OF THE PLASTIC LINER HIGH MOLECULAR WEIGHT (HWM) AND ULTRA-HIGH MOLECULAR WEIGHT (UHMW) LINER The plastic liner under the chain (and on the slopes, if applicable) must be inspected for damage and wear. Replace the liner if it is worn through at any spot. If any foreign material should become lodged between the liner and the body of the trailer, remove it by blowing or vacuuming it out. CAUTION WARNING NOTE There is absolutely no warranty, expressed or implied, on the chain or drive system if the system is not maintained properly, is misused or is overloaded. This includes, but is not limited to the hauling of corrosive materials such as fertilizer, sludge, brewer’s mash or corn gluten. Use eye protection when using air to blow material from underneath the liner to help prevent injuries from flying particles. Getting inside the trailer with the door(s) closed or the hydraulic system energized can result in serious injury or death. Open door(s) and disable all hydraulic systems before entering the trailer. Jun 12 Rev 9 ©2012-2013 Trinity Trailer Mfg., Inc. COATING CARE AND CORROSION PREVENTION Your Eagle Bridge™ trailer is coated with a high-performance polyurethane paint. This paint is designed to give you durable performance in the rugged environments encountered by your trailer. The best way to preserve the finish on your trailer and help prevent corrosion is to wash it regularly, especially after it has been used around road salt or other ice melting agents, road oil or tar, or any other potentially corrosive material. Use warm water with a mild detergent and allow the trailer to air dry. Use of abrasive or caustic cleaning agents will void the paint warranty. Hauling corrosive products such as salts and fertilizers will also void the paint warranty. Small nicks or chips in the paint can occur with normal use. Any chips or scratches in the finish should be repaired with matching touch-up paint. This is especially important for carbon steel trailers, as even small areas of bare metal can corrode quickly. The cost of repairing any chips is the responsibility of the owner. Removal or disrepair of mud flaps on either the tractor or the trailer will void the paint warranty. Frequent use of the trailer on gravel roads will also void the warranty. If your trailer has aluminum wheels, you should clean them regularly with mild detergent and water to prevent corrosion. Use a non-abrasive, non-acidic cleanser to remove heavy build-up when necessary. Do not use abrasive metal polishes or scouring pads. STAINLESS STEEL BODIES Trailers with stainless steel bodies require the same care as painted trailers. Regular washings to remove road grime and remnant corrosive material will help maintain the finish and help prevent corrosion. Use warm water with a mild detergent and allow the trailer to air dry. Use of abrasive cleaning agents will dull and scratch the finish. Use of carbon steel utensils will result in surface contamination. It is particularly important to rinse off the trailer after hauling any material containing chlorides as prolonged contact with chlorides may dull the finish and leave it subject to pitting. Carbon contamination of stainless steel will cause localized rust spots. The breakdown of the carbon on the surface of stainless steel does not affect the structural integrity of the trailer. INTERIOR COATING The interior of your trailer may have a coal tar epoxy coating to help prevent corrosion. There are no physical hazards associated with the coating once it has fully set. However, Jun 12 Rev 10 ©2012-2013 Trinity Trailer Mfg., Inc. problems can arise if the coating is heated when repairing the trailer. The coating must be removed by abrasive blasting before any work can be done on an area of the interior or exterior of the trailer body. Figure 5 shows a warning label which was placed on the trailer at the factory regarding this coating. Figure 5-Coal Tar Epoxy Decal PERSONAL PROTECTIVE EQUIPMENT WARNING ? Use a dual-cartridge respirator with organic vapor cartridges when removing the coal tar epoxy coating by abrasive blasting. ? Use the respirator when cutting, grinding or welding the area where the coating was removed. ? Use a face shield and/or goggles when performing any of the above operations. ? It is the responsibility of the individual using the respirator to verify that it meets all local and federal (OSHA) safety requirements. Contact our customer service department if you have any questions regarding ventilation while working around this product. CLEANING THE INTERIOR If product accumulates underneath the chain and flaps, it can usually be removed by lifting each flap and vacuuming, sweeping or blowing the material out. Under no circumstances should you get into the trailer with the conveyor system running or enabled (See Figure 6). For your safety, completely disable the hydraulic system before entering the trailer (See Figures 7a, 7b and 7c). Failure to follow the following instructions could result in severe physical injury or death. NOTE Trinity Trailer Manufacturing is not responsible for the removal or after-sale application of coal tar epoxy coating. The above information is provided for informational purposes only. Jun 12 Rev 11 ©2012-2013 Trinity Trailer Mfg., Inc. Figure 6-Entry into Trailer Decal Figure 7a-Moving Conveyor Parts Decal Figure 7b-Moving Winch Parts Decal Figure 7c-Moving Conveyor Parts Decal SPRING SUSPENSION INSPECTION AND MAINTENANCE SPRING SUSPENSION INSPECTION The following are Hutchens Industries’ instructions for suspension inspections. Trinity Trailer Manufacturing requires you to show proof of compliance with these instructions prior to providing any warranty service. The first maintenance check should be performed after an initial break-in-period of about 1,000 miles. A visual inspection of all suspension components and attachment welds should be performed to reveal any obvious problems, such as cracks or unexpected wear. Jun 12 Rev 12 ©2012-2013 Trinity Trailer Mfg., Inc. During this “walk-around”, it is essential to also check the torque on all suspension fasteners. In the course of the initial “shake down” period in which the components of the suspension “seat in”, as much as 25% of the original clamp load of the bolted fasteners can be lost. After the parts of the suspension have worked together for a very short period of time, re-torquing the bolts is necessary to ensure that undue movement, which results in excessive wear, does not occur. Visual inspections and re-torquing are maintenance procedures that are performed every four months throughout the life of the trailer. Begin each inspection with a review of the Hutchens torque decal for the appropriate torque values for each suspension fastener, Figure 8 (the decal can be found on the road side of the trailer and is shown for your convenience). The oiled torque values in the first column are for new fasteners with lubricated threads. When you are installing new components, we recommend you lubricate the threads and use torque values in this column. For maintenance checks on fasteners that have been in service, use the higher torque values in the dry thread column. It’s important that you check all bolts and nuts to insure that the recommended torque values are being maintained. You cannot rely on your visual inspection to detect loose fasteners. USE A TORQUE WRENCH Figure 8-Spring Suspension Torque Requirements AXLE CLAMPS AND SPRINGS Check the torque on the U-bolt nuts by alternately tightening opposing corners of the clamp assembly, as shown in Figure 9. Dry threads should be tightened to 470 ft-lbs. Jun 12 Rev 13 ©2012-2013 Trinity Trailer Mfg., Inc. Carefully inspect the spring and axle clamp components for any signs of wear or cracks and replace if visible wear or cracks are present. Figure 9-Spring Suspension Axle Clamp Tightening Sequence RADIUS RODS The 1” radius rod attachment bolts (Figure 10) at the hangers and spring seats should be checked for proper torque on both the adjustable and non-adjustable radius rods. Loose operation of this bolt can result in wear, requiring new components to be installed to avoid structural damage. If you observe any visible wear or loosening in the bushing, it is imperative that you immediately replace the radius rod bushing and bolt. Failure to replace these components will result in damage to the hanger, spring seat and/or the radius rod. Next, check the radius rod clamp bolts (Figure 10) for proper torque. If the clamp bolt has not been properly maintained, wear between the radius rod screw and the eye end may be observed. If so, the entire radius rod must be replaced. Simply re-tightening the clamp bolt or replacing it will not correct the problem. Figure 10-Radius Rod Bolts Jun 12 Rev 14 ©2012-2013 Trinity Trailer Mfg., Inc. ROCKER BUSHINGS Check the rocker bushing clamp bolts (Figure 11) for proper torque. If the bolts are loose, you must inspect the rocker to ensure that no structural damage has occurred. One way this can be done is by raising the trailer until the trailer weight is taken off of the springs. If the rocker is displaced or if the joint is loose, the rocker should be removed and the rocker and/or rocker bushings replaced. Again, visually inspect the condition of all the rocker/rocker hanger assembly components and replace if visible wear is present. Figure 11-Rocker Bushing Bolts HANGERS Check all of the spring retainer bolts (Figure 12) found in the rockers and rear hangers. Trailers that are operated with loose fasteners for any period of time will result in irreversible suspension damage and possible loss of vehicle control. Re-tightening a worn fastener will not correct a situation created by loose operation Figure 12-Spring Retainer Bolts Jun 12 Rev 15 ©2012-2013 Trinity Trailer Mfg., Inc. SPRING SUSPENSION ALIGNMENT Trinity Trailer aligns the suspension using industry-standard alignment procedures. After an initial break in period of 1,000 miles, loosened bolts, nuts and springs can affect the alignment. The surface of the road and type of terrain can also affect the suspension alignment. Proper and preventive maintenance after the initial alignment is the responsibility of the owner/operator. If you have not been properly trained in suspension alignment procedures, have the work done by a qualified technician. Figure 13 shows the decal that was placed on your trailer when it was built. Figure 13-Suspension Alignment Decal Trailer axle alignment should be checked (and adjusted if necessary): ? After the initial break-in of 1,000 miles ? Following any maintenance or repair procedures performed on the suspension Perform the suspension inspection and re-tightening procedures prior to alignment. The following information is the standard recommendation for suspension alignment. This information is applicable to all trailers with spring suspensions. Before the trailer can be aligned properly it must be unloaded. Free the suspension of any binding by pushing the trailer backwards and then pulling forward. The trailer must be level, both side-to-side and front-to-rear. Neither the service nor parking brakes should be applied during the measurement procedure. Jun 12 Rev 16 ©2012-2013 Trinity Trailer Mfg., Inc. The axle position may be determined using any established mechanical or optical (laser) measurement equipment. Measure distances A and B from the kingpin to the front axle. These dimensions must be within 1/8” of each other. If adjustment is needed, loosen the radius rod clamp bolts and turn the adjustment screw as required. When the front axle is positioned correctly, align any succeeding axles with the front axle by measuring distances C and D. These dimensions must be within 1/16” of each other. (Figure 14) After the alignment has been completed on all axles, check to make certain the radius rod clamp bolts and all other fasteners are tightened to the required torque. Figure 14-Suspension Alignment Requirements Jun 12 Rev 17 ©2012-2013 Trinity Trailer Mfg., Inc. AIR-RIDE SUSPENSION INSPECTION AND MAINTENANCE AIR-RIDE SUSPENSION INSPECTION (HENDRICKSON HT-SERIES, INTRAAX® AND PARALIFT™ ULTRA) DAILY Verify that the trailer is level and riding at the correct height. EVERY 30 DAYS Review the clearances around the air springs, tires, shock absorbers and all other moving parts. Bolts should be secure and axle connections tight. Any signs of wear should be evaluated and corrected as necessary. EVERY 90 DAYS In addition to the above, inspect all welded connections, frame attachment joints, cross member structures and all pivoting and clamping connections. HT SERIES TORQUE REQUIREMENTS The following torque values are for the HT-Series air suspensions. A decal similar to Figure 15 will appear on your trailer.

PARALIFT™ ULTRA TORQUE REQUIREMENTS The following torque values are for the ParaLift™ Ultra auxiliary liftable axle (Figure 17). Figure 17-ParaLift™ Ultra Torque Specifications WARNING AIR-RIDE SUSPENSION ALIGNMENT Trinity Trailer aligns the suspension using industry-standard alignment procedures. After an initial break-in period of 1,000 miles, loosened bolts, nuts and springs can affect the alignment. The surface of the road and type of terrain can also affect the suspension alignment. NOTE Torque values are specified for the fasteners in the condition in which they were supplied by Hendrickson. Do not apply any additional lubricants. Over-torquing could result in fastener failure which could lead to a crash. Do not tighten the fasteners beyond the recommended torque. Jun 12 Rev 20 ©2012-2013 Trinity Trailer Mfg., Inc. Proper and preventive maintenance after the initial alignment is the responsibility of the owner/operator. If you have not been properly trained in suspension alignment procedures, have the work done by a qualified technician. Figure 18 shows a decal that was placed on your trailer when it was built. See Figure 14 for the suspension alignment requirements. Figure 18-Suspension Alignment Decal QUICK-ALIGN® CONNECTION Hendrickson suspensions use a non-welded Quick-Align® feature (Figure 19). The following guidelines must be used when aligning an air-ride suspension. Figure 19-Air-ride Suspension Alignment Components Jun 12 Rev 21 ©2012-2013 Trinity Trailer Mfg., Inc. 1. Remove and discard the pivot bolts and nuts on the forward axle connections and replace with new shear-type bolts and torque-prevailing nuts. Tighten the nuts on the pivot bolts to hold the flanged washers in place against the adjustment guide, but loose enough to permit the hardened flat washers to rotate freely. WARNING WARNING 2. On the previously mentioned pivot connection, inspect the orientation of the square hole (Figure 20) on the eccentric flange washer (outboard side). The square hole should be at the 12:00 position (middle of the alignment adjustment); adjust if necessary. To adjust the eccentric, insert a ½” square drive breaker bar into the square hole on the eccentric flanged washer. Rotating the eccentric flanged washer clockwise (45° maximum) or counterclockwise (45° maximum) will provide fore and aft positioning. Figure 20-Air-ride Suspension Alignment Do NOT re-use the pivot joint fasteners. A new pivot bolt and shear-type bolt must be installed to prevent pivot connection failure due to insufficient clamp load. These parts are contained in Hendrickson kit S-24679, available from our parts department. No liability is assumed for pivot joint failures when either a shear-type bolt or torque-prevailing nut is reused. Do not apply or allow any type of lubricant to contact the threads of pivot connection fasteners. Lubricant will reduce the friction between the threads of the pivot fastener and nut. Failure of the pivot fastener could occur. Jun 12 Rev 22 ©2012-2013 Trinity Trailer Mfg., Inc. 3. Repeat step 1 and 2 on the remaining connections. 4. Follow the measurement steps in the spring suspension alignment process above. 5. If additional axle movement is necessary, adjust the eccentric washer on the opposite side of the forward axle from the 12:00 position. 6. After achieving proper alignment of the forward axle, snug the pivot connections and recheck alignment. 7. Apply torque to the torx-head portion of the shear-type bolt until it shears off of the hex head. 8. Align additional axles to the forward axle by rotating their eccentric flanged washer(s) until both ends of the axle are an equal distance from the front axle (see Figure 12). Repeat steps 1, 2,3,5,6 and 7. PARALIFT™ ULTRA ALIGNMENT Only the toe setting needs to be checked on the ParaLift™ Ultra. 1. Lift the axle until the tires are free to spin. Make a line around each tire at the center of the tread using a paint marker. 2. Use a measuring tape to measure the distance between the lines at the front and rear of the tires at the same height as the axle. 3. If the distance between the lines is 1/16” to 1/8” at the front (toe-in condition), no adjustment is necessary. 4. If the measurements do not meet the above requirements, loosen the tie rod clamp bolts, stabilizer mounting U-bolts (if applicable) and nuts. Rotate the tie rod tube until there is a toe-in setting of 1/16” to 1/8” (see Figure 21). 5. Tighten and torque the hardware to the specifications given in Figure 17. NOTE Be sure that the axle movement occurs without compressing the Tri-Functional™ Bushing. Jun 12 Rev 23 ©2012-2013 Trinity Trailer Mfg., Inc. Figure 21-ParaLift™ Alignment HUB AND WHEEL INSTALLATION AND MAINTENANCE In addition to following the instructions below, it is recommended that you read and understand the federal regulations relating to tire and wheel handling and maintenance. A copy of these can be obtained through the U.S. Government printing office, your local library or the internet. Refer to 29 CFR 19103177, Servicing Multi-Piece and Single Piece Rim Wheels. Figure 22-Wheel Hardware Decal Jun 12 Rev 24 ©2012-2013 Trinity Trailer Mfg., Inc. BALL SEAT MOUNT WHEELS Ball seat wheels have spherical chamfers, or “ball seats”, machined into each stud hole. The inner and outer cap nuts center the wheels by seating these seats. The mounting method is also commonly referred to as “stud piloted”. WARNING ? Use correct, matched parts when mounting the wheels. ? Use the correct size of studs and capnuts (described below) for the type of wheels you are using. ? Do not combine ball seat wheels with pilot mount wheels (described below). ? Do not use heat to remove frozen capnuts. This could result in component failure. ? Only use tires that are within 3/4" of the same rolling circumference. Greater difference in circumference can cause unstable operation and reduce component life. ? Tighten all capnuts in the proper sequence and to the required torque. ? Use the correct hand thread for each axle. ? Do not use Grade 5 inner capnuts with aluminum wheels. Ball Seat Mount Steel Wheels When using steel wheels, use 1.31” to 1.44” dual wheel stud standouts. Use Webb 107080RH and 107091LH inner capnuts (or equivalent) and Webb 178910RH and 178921 LH outer capnuts (or equivalent). Install left-hand threads on the roadside of the vehicle and right-hand threads on the curbside of the vehicle. Capnut tightening sequence and torque values are show in Figure 23. Ball Seat Mount Aluminum Wheels When using aluminum wheels, use 1.31” to 1.44” dual wheel stud standouts. Use Webb 105988RH and 105989LH inner capnuts (or equivalent) and Webb 178910RH and 178921LH outer capnuts (or equivalent). Install left-hand threads on the roadside of the vehicle and right-hand threads on the curbside of the vehicle. Capnut tightening sequence and torque values are shown in Figure 23. The use of 1.75” to 1.87” stud standouts is not recommended because of the lack of standardization and possible improper installation. The long stud standout must not be used with dual steel wheels. If your hubs have long standouts, use Webb 105988RH and 105989LH Grade B inner capnuts with aluminum wheels only. Follow the information below when working with wheels on your trailer. Failure to do so can lead to loose wheels or component failure, resulting in loss of property, serious bodily injury or death. See Figure 22. Jun 12 Rev 25 ©2012-2013 Trinity Trailer Mfg., Inc. Combining Ball Seat Mount Steel and Aluminum Wheels When using a combination of aluminum (outer) and steel (inner) wheels, use 1.31” to 1.44” dual wheel stud standouts. With a combination of steel and aluminum wheels, it is critical that the correct hardware be used. Use Leland W620 and W621 inner capnuts (or equivalent) and Webb 178910RH and 178921LH outer capnuts (or equivalent). Install left-hand threads on the roadside of the vehicle and right-hand threads on the curbside of the vehicle. Capnut tightening sequence and torque values are shown in Figure 23. WARNING Mounting Ball Seat Mount Wheels (Figure 23) Wheels must be correctly assembled using the correct capnuts and must be correctly aligned to assure maximum service life and safety. 1. All parts must be clean and free of rust, dirt or paint. 2. Position the inner wheel over the studs, being careful not to damage the threads. 3. Install the inner capnuts and tighten to 50 ft-lbs in the sequence shown in the figure below. Tighten to full torque using the same sequence. 4. Position the outer wheel over the inner capnuts, being careful not to damage the threads. 5. Install the outer capnuts and tighten to 50 ft-lbs, again using the sequence shown below. Tighten to full torque using the same sequence. Figure 23-Ball Seat Mount Wheel Torque Specifications A polyethylene spacer must be placed between the two wheels; without it, corrosion will occur. This could lead to component failure and result in loss of property, serious bodily injury or death. Jun 12 Rev 26 ©2012-2013 Trinity Trailer Mfg., Inc. IMPORTANT The capnuts must be re-tightened after the first 50 to 100 miles of service. 1. Loosen the outer capnuts. 2. Check the torque of the inner capnuts in the tightening directions. 3. Tighten the outer capnuts to 50 ft-lbs in the sequence shown above. Tighten to full torque using the sequence shown above. PILOT MOUNT WHEELS Pilot mount wheels have stud holes that are reamed straight through the wheel. Pilot bosses machined on the hub fit tightly to the center hole of the wheel. Pilot mount wheels are secured with right-hand thread flange nuts on studs which have at least 2.16” standouts. This mounting method is also commonly referred to as “hub piloted”. WARNING ? Use correct, matched parts when mounting the wheels. ? Do not combine ball seat mount wheels (described above) with pilot mount wheels. ? Do not use ball seat nuts with pilot mount wheels. ? Do not use heat to remove frozen flange nuts. This could result in a component failure. ? Only use tires that are within 3/4" of the same rolling circumference. Greater difference in circumferences can cause unstable operation and reduce component life. ? Tighten the flange nuts in the proper sequence and to the required torque. Mounting Pilot Mount Wheels (Figure 24) 1. All parts must be clean and free of rust, dirt or paint. 2. Position the inner wheel over the studs, being careful not to damage the threads. 3. Position the outer wheel over the studs, being careful not to damage the threads. 4. Install the flange nuts and tighten to 50 ft-lbs in the sequence shown below. 5. Make sure the surface of the wheel which is contacted by the flange nut is flat. 6. Tighten the nuts to 450-500 ft-lbs using the same sequence. NOTE The torque listed is for dry threads with no lubricant. Proper capnut torque is important. Insufficient torque can cause stud breakage and damages the ball seats. Excessive torque can overstress the studs and strip the threads. Follow the information below when working the wheels on your trailer. Failure to do so can lead to loose wheels or component failure, resulting in loss of property, serious bodily injury or death. See Figure 22. Jun 12 Rev 27 ©2012-2013 Trinity Trailer Mfg., Inc. Figure 24-Pilot Mount Wheel Torque Specifications WARNING RECOMMENDED PROCEDURE FOR REPLACING STUDS ? When a broken stud is replaced, the stud on each side of it should also be replaced. ? If more than two studs are broken, replace all of the studs. ? Use the correct stud size. If the correct length stud is not used, the back nut (jam nut) may not seat firmly against the drum. ? Too much “standout” from the mounting face of the hub may make it impossible to secure the inner wheel against the hub face (ball seat mount wheels). ? If replacing studs on ball seat mount wheels, remember that right-hand studs go on the right-hand side (curbside) of the vehicle and left-hand studs go on the left-hand side (roadside). NOTE The torque listed is for dry threads with no lubricant. Proper flange nut torque is important. Insufficient torque can cause stud breakage and damages the ball seats. Excessive torque can overstress the studs and strip the threads. The flange nuts must be re-tightened after the first 50 to 100 miles of service. Tighten them to 450-500 ft-lbs in the sequence shown above. Failure to re-torque the flange nuts could result in the wheel becoming loose on or falling off of the trailer during operation resulting in property damage, personal injury or death. Jun 12 Rev 28 ©2012-2013 Trinity Trailer Mfg., Inc. HYDRAULIC SYSTEM SERVICING TRACTOR HYDRAULIC SYSTEM REQUIREMENTS Gear Pump Requirements (Volume): 10-15 GPM (Gallons per Minute) Reservoir capacity: Minimum 5 Gallons Hyd. Pressure Requirements/Bypass Settings: 2500 PSI/3000 PSI Tractor hydraulic oil must be maintained at all times. Neglect of the tractor oil will result in premature hydraulic component failure. Pressure line filters are optional. PRESSURE FILTERS Trailers with combination hydraulic systems that combine a PTO system with an electric or gas system will have an inline pressure filter. The filter has a sight glass on top of the housing unit that indicates the condition of the filter. If the sight glass shows red, it is time to replace the cartridge inside of the filter. These filters DO NOT have a bypass option. As the filter becomes clogged, it will slow down the flow of oil which will slow the unloading of the product. HYDRAULIC CYLINDER MAINTENANCE The hydraulic cylinder which operates the rear door(s) (if installed) should be inspected before each use. See Figures 25 and 26 for precautionary measures that must be taken before performing any maintenance. ? Repair any leaking fittings found before operating the cylinder. ? Keep the cylinder clean and free from foreign materials. ? If there is leakage across the cylinder or the cylinder housing or the shaft is damaged, replace the cylinder. ? A light film of oil on the shaft of the cylinder is normal and should not be mistaken as a leak. ? Small burrs or scratches should be removed from the shaft using a honing stone or emery cloth before use of the cylinder. Figure 25-Hydraulic System Pressure Decal Figure 26-Hydraulic Leak Decal Jun 12 Rev 29 ©2012-2013 Trinity Trailer Mfg., Inc. HYDRAULIC LINES AND FITTINGS Visually inspect the hoses and fittings for leaks, cracks, chafing or crimping. Since the hydraulic system operates at high pressures, replace any components which are worn or damaged before use. HYDRAULIC FLUID RECOMMENDATIONS ? The hydraulic oil level in the tank should be no lower than four inches from the top of the tank. Check the oil level daily. Refill as required. ? The filter in the system should be changed after the first 50 hours of operation and every 250 hours thereafter. Under dirty or dusty conditions, change the filter more frequently. ? Recommended fluid-Chevron Hydraulic Oil AW ISO 32 or equivalent. HYDRAULIC VALVE MAINTENANCE The seals in the valves of the hydraulic system can become dirty or worn and allow hydraulic fluid to leak across the spool. If this happens in a flow control valve (used with a PTO system) or a door valve, contact our parts department toll free at 800-235-6577 to order a replacement o-ring kit (Figures 27 and 28).

Gasoline engines equipped with electric starters have a 12-volt battery which can be unsafe if handled improperly. Follow these precautions when servicing the battery. Jun 12 Rev 31 ©2012-2013 Trinity Trailer Mfg., Inc. ? The battery can produce hydrogen gas and can explode, causing serious bodily injury. Do not smoke while checking or servicing the battery. Keep open flames and sparks away from the battery. ? To avoid a short circuit across the battery, which can result in serious bodily injury, never allow tools or metal objects to contact the battery posts and the trailer. Disconnect the negative battery cable when checking or servicing the battery. ? Keep battery fluid away from children and pets. ? Do not store the battery where there is a likelihood of open fire, sparks or accessibility to children. Some areas require that the engine be equipped with a spark arrester to reduce the potential for the exhaust from the engine to cause a fire. Your engine should have had one installed when the engine was installed on your trailer. You should remove the arrester and clean it in accordance with the engine manual at least once every 100 hours of operation. ANTI-LOCK BRAKE SYSTEM (ABS) The Meritor WABCO (previously Rockwell) 4S/2M anti-lock brake system is used on your trailer. This system exceeds the requirements of the Transportation Code of Federal Regulations, 49 CFR 571.121. You should use your brakes as you normally would when you are driving. Apply the brakes the same way you would if your trailer didn’t have an ABS system. You should not need to pump the brakes if the system is working properly. You may notice some chassis vibration when excessive brakes are applied. This is normal; the system senses the wheel rotation speed and will modulate the air pressure if it detects a wheel lock-up condition. Figure 30-Engine Exhaust Decal Jun 12 Rev 32 ©2012-2013 Trinity Trailer Mfg., Inc. Read the following decal (Figure 31) which was supplied by Meritor WABCO and was put on your trailer when it was built. Figure 31-ABS Indicator Decal You should note that the vehicle must be traveling at least 5 mph for the light to illuminate. If the light stays on, contact an authorized Meritor WABCO service center to remedy the problem before continuing to operate the trailer. ABS service must be performed by a qualified technician to ensure the brakes on the trailer operate properly. Read the following decals (Figures 32a and 32b) and then follow the instructions and precautions. NOTE Like all anti-lock braking systems, this system will allow a small amount of wheel lock-up. Figure 32a-ABS Servicing Decal Figure 32b-Brake System Component Decal Jun 12 Rev 33 ©2012-2013 Trinity Trailer Mfg., Inc. IGNITION POWER ACTIVATION Ignition Power Activation is the process of using the vehicles ignition switch (or interrupting the power on the blue wire by some other means) to display blink codes on the trailer ABS indicator lamp located on the side of the trailer. This method is for constant power vehicles only. To obtain blink codes using ignition power activation, perform the following procedure: 1. Turn the ignition switch on for no longer than 5 seconds. The ABS indicator lamp will be on. 2. Turn the ignition switch off. The ABS indicator lamp will go out. 3. Turn the ignition switch on. The ABS indicator lamp will then come on, and then go out. 4. The blink code will be displayed three times by the ABS indicator lamp on the trailer. REAR IMPACT GUARD Your trailer meets the latest rear impact guard requirements of the Transportation Code of Federal Regulations, 49 CFR 571.223 and 571.224. If the guard is damaged, the Federal Highway Administration requires that it be repaired such that it will again be in compliance with these regulations in a “like new” condition. Have a qualified mechanic nspect any damage before continued use of your trailer. Contact our repair department toll free at 800-235-6577 if the guard needs to be repaired.

OPERATING INSTRUCTIONS COUPLING THE TRAILER To couple the trailer to the tractor safely, follow the procedures below. Figures 33a and 33b show warnings which were placed on your trailer when it was built and relate to the safe coupling of the trailer. Figure 33a-Coupling Decal Figure 33b-Winch Handle Decal 1. Check the kingpin and surrounding area for cracks or damage. 2. Clean and lubricate the fifth wheel in accordance with the tractor manufacturer’s recommendations. 3. Position the fifth wheel for coupling with the plate tilted down toward the aft end of the tractor, the jaws opened, and the safety unlocking handle in the automatic lock position. If the tractor is equipped with a sliding fifth wheel, lock it in place. 4. Ensure the spring brakes are applied on the trailer. 5. Make certain the doors are securely closed on the trailer. 6. Align the tractor with the front of the trailer and back up until the fifth wheel just touches the trailer. 7. Engage the parking brake and shift the tractor into neutral. 8. Adjust the height of the landing legs so the trailer is level with the fifth wheel. 9. Check to make certain that the kingpin is aligned properly with the fifth wheel. 10. Connect the service and emergency air lines from the tractor to the gladhands on the front of the trailer. Secure the air lines so they will not be damaged when the tractor is backed up under the trailer. 11. Apply the trailer parking brakes by pulling the trailer brake knob in the tractor. 12. Release the tractor brakes by pushing in the tractor brake knob. 13. Back the tractor slowly under the trailer until the kingpin engages in the fifth wheel and locks in place. 14. Raise the landing legs slightly off the ground (see Figure 33b) and pull on the trailer gently with the tractor while the trailer brakes are still locked in the cab to ensure the kingpin is fully engaged. 15. Inspect the fifth wheel area thoroughly to make certain the connection between the tractor and trailer is secure. Make certain that the locking lever is in the locked position. Jun 12 Rev 35 ©2012-2013 Trinity Trailer Mfg., Inc. 16. Attach the electrical cable from the tractor to the trailer, making sure the connector securely engages the socket. 17. Make certain the air lines and electrical cable are supported to prevent them from chafing or being snagged while connected. 18. Raise the landing legs completely, leave in gear and securely place the crank in its bracket (See Figure 33b). No one should ever be allowed to ride on or in the trailer while it is being towed or has the door closed and/or hydraulic system enabled (Figure 34a and 34b). Figure 34a-Riding in Trailer Decal Figure 34b-Getting inside Trailer Decal 1. Before uncoupling the trailer, move the truck to an area with a level surface capable of supporting the weight of the trailer. 2. Stop the truck with the tractor aligned with the trailer. 3. Lock the trailer brakes and back the tractor up slightly to relieve the pressure on the locking jaws. Engage the parking brake on the tractor. 4. Lower the landing legs until they contact and just start to put pressure on the ground. 5. Disconnect the air lines and electrical cable from the trailer. 6. Move the locking lever on the fifth wheel to the open position. 7. Pull the tractor forward to disengage the kingpin. Stop the tractor before the fifth wheel comes out completely from underneath the trailer. 8. Adjust the landing legs to raise the trailer so it will clear the fifth wheel. 9. Pull the tractor forward to clear the trailer. A NOTE ON AIR PRESSURE U.S. Federal Motor Vehicle Safety Standards part 121 now requires that the air compressor on all tractors pulling trailers must have higher air pressure levels in the supply line. This is required because the performance of modern brake systems requires higher pressures. Because of this, you must check the pressure settings on the compressor governor on your tractor. If set properly, the compressor should cut-in at 105 psi and should cut-out at a minimum of 120 psi (Figure 35). Jun 12 Rev 36 ©2012-2013 Trinity Trailer Mfg., Inc. Do not attempt to tow your Eagle Bridge™ trailer if your tractor does not meet these requirements. Figure 35-Air Pressure Decal LOADING THE TRAILER When loading the trailer, the load must be distributed uniformly from the rear to the front. Read the following decals (Figures 36a, 36b and 36c) regarding loading safety. If you haul products that are granular and tend to flow, it is strongly recommended that you load the trailer from the rear forward. This will reduce the tendency for the material to force the chain flaps up, allowing the product to become lodged underneath the flaps. Your chain will last longer and require less frequent maintenance if you load in this manner. If your trailer has a slide-up small door, make sure the safety latches at the bottom of the large door are securely latched before loading or towing the trailer.

CONVEYOR OPERATION ELECTRICALLY-DRIVEN HYDRAULIC SYSTEM OPERATION (FIGURE 53) 1. Ensure the rear door is open. (Procedures for opening the door are following this procedure). 2. Make sure the electric motor is in the ‘off’ position. 3. Rotate the needle valve (Figure 54) so the lever is toward the front of the trailer. 4. Plug the electric motor into an approved receptacle which is appropriately sized and has the necessary safety mechanisms to properly operate the motor. It is the operator’s responsibility to ensure that the installation is safe. 5. Switch the electric motor on. 6. If your trailer has a hydraulic door, place the push-pull valve (Figure 56) in the ‘conveyor’ position. 7. Move needle valve 1 or 2 clicks to start the conveyor. As the load is discharged, the conveyor speed can be gradually increased. If the conveyor does not start moving, check the pressure reading on the gauge. If it is still increasing, wait until it reaches full operating pressure (2500 PSI). If conveyor still does not move, DO NOT increase the flow control setting. Call Trinity Trailer Mfg. at 800-235-6577 for assistance. GAS ENGINE-DRIVEN HYDRAULIC SYSTEM OPERATION (FIGURE 52) 1. Ensure the rear door is open.

OPERATING THE PNEUMATICALLY-ACTUATED FRONT SEAL Some trailers are equipped with a front seal (Figure 95) operated with air pressure from a pneumatic reservoir. If the reservoir does not have sufficient pressure in it to actuate the seal, the trailer should be connected to the air supply from the tractor. Figure 95-Pneumatically-Actuated Front Seal The control valve used to operate the front seal is located at the rear of the trailer near the controls for the conveyor and/or door. Raise the toggle valve up to open the seal and down to close it. The rubber seal must have a chain crossbar from the conveyor system located under it in order to obtain a good seal IMPORTANT The applicable procedure for closing the rear door(s) must be followed before the front seal is closed. The front seal must be opened before the trailer is unloaded. WARNING WARNING Do not get behind a loaded trailer with the door(s) open. The trailer’s contents could spill on you causing serious injury or death. Moving conveyor parts can crush and cut and cause serious bodily injury or death. Keep away from all moving parts while they are in motion. Jun 12 Rev 97 ©2012-2013 Trinity Trailer Mfg., Inc. USING THE REMOVABLE TAIL FINS Some trailers are equipped with removable tail fins. These fins are used while unloading the trailer to help direct the load onto a hopper or an elevator. Use of these removable tail fins on the road is a violation of the federal rear impact guard law (Figure 96). Trinity Trailer is not liable for any action against the owner or operator resulting from installation of these tail fins on the trailer while the trailer is on the road. It is the responsibility of the owner or operator to verify that the tail fins are removed from the rear of the trailer before using the trailer on the road. You will find the following decal located on each tail fin. Figure 96-Tail Fin Decal Figures 97 and 98 show how the tail fins are stowed when they are not in use and how they mount to the rear of the trailer, respectively. Figure 97-Tail Fin Stowed Figure 98-Tail Fin Mounted Jun 12 Rev 98 ©2012-2013 Trinity Trailer Mfg., Inc. TARP SYSTEMS Your trailer may be equipped with one of three types of tarps. The standard tarp is a manual rollover tarp that is attached to the curbside of the trailer. When the tarp is rolled over the top of the trailer, secure it in place with the attached straps to the ratchets which are mounted on the roadside of the trailer. If there is a flap on the front or back of the tarp, secure with bungees to make sure the tarp seals. The handle for the tarp is removable and is stowed behind the ladder on the roadside of the trailer (Figure 99). Do not leave the handle attached to the tarp while driving. Figure 99-Rollover Tarp Handle Stored The second type of tarp is a Shur-Lok® style roll tarp system by Shur-Co®. This tarp is similar to the standard rollover tarp; however, it does not use straps to secure it when unrolled. On the roadside of the trailer is a 4-inch latch plate, or overhang, attached to the top of the trailer. When you unroll the tarp, continue rolling it past the latch plate until it is completely unrolled. Continue to turn the crank handle in the same direction so the tarp starts rolling up underneath the latch plate. Once the tarp has tension on it, lock the handle in the crank retainer on the roadside of the trailer (Figure 99). The Shur-Co® illustration in Figure 102 shows these steps. Figure 100 shows this tarp rolled up. The third type of tarp is an electrically operated Shur-Lok® style. This tarp has an electric motor and control arm system. A rocker switch on the front of the trailer operates the system. To open the tarp, push and hold the rocker switch until the tarp rolls over the trailer and against the tarp stops. To close the tarp, push and hold the rocker switch until the tarp has rolled all the way down and rolled back up against latch plate. Jun 12 Rev 99 ©2012-2013 Trinity Trailer Mfg., Inc.

LADDER, WALKWAY AND CATWALK SAFETY You may have one or more ladders, walkways or catwalks on your trailer. If you do, review the following information thoroughly. Trinity Trailer has made every effort to reduce or eliminate the risk involved with using these devices. Although there is always a risk in working on elevated areas, it is a fact that the vast majority of accidents involving ladders result from the failure to exercise care. Proper training, as well as routine inspections and maintenance can substantially reduce the number or ladder related injuries. Never stand on the top two steps of any ladder or the top cap of a ladder. This could cause you to become off-balance resulting in a fall. Always maintain at least three points of contact with the ladder (2 feet and 1 hand or 2 hands and 1 foot should be in contact with the ladder at all times). Do not over-extend sideways. Use the belt buckle rule: Keep your belt buckle positioned between the side rails at all times, this will maintain your center of gravity in the proper position. Below are twelve cautions and warnings about ladders, walkways and catwalks that may be on your trailer. Review each of these thoroughly before using the trailer.
