Preventive Maintenance: Regularly scheduled maintenance is critical for the long productive service life expected from your baler or compactor.  Failure to properly maintain your equipment leads to added repair costs, extended downtime, and safety concerns.

Preventive Maintenance Plans are available on all Harmony Enterprises’ equipment.  They are an extremely affordable and convenient way to ensure the long life and reliability of your investment.

What Is Included In Your Preventive Maintenance Plan?

Your regularly scheduled baler and compactor maintenance should include the following items:


  • Inspect all nuts and bolts during the first week of use, and then monthly thereafter.
  • Check hydraulic oil reservoir for proper oil level with the cylinder fully retracted. Maintain proper oil level in the reservoir with a high quality all-weather hydraulic oil such as Conoco 5W-20 or equivalent for compactors and Conoco MV32 or equivalent for balers. A “Fill to Here” decal is provided to help maintain the proper level. In addition, check for any leakage, kinks, or other damage to the hydraulic hoses and replace if necessary.
  • Check the power unit. Keep the power unit clean and free of debris in order to provide a clean airflow around the unit. Wipe all grease, dust, and dirt from the outside of the control box.
  • Check that all safety guards and access covers are secure and in the proper condition before operation.


  • Grease the lower door hinges and lock assembly with a needlepoint grease gun.
  • Check all nut and bolts. Inspect the overall condition of the equipment and the surrounding work area.


  • Have a licensed electrician inspect the electrical system. All electrical connections should be examined and the motor amp draw should be checked. Recording successive readings helps prevent future failures.
  • Maintain the hydraulic system. Drain and refill the reservoir with high quality all weather hydraulic fluid such as Conoco 5W-20 or equivalent for compactors and Conoco MV32 or equivalent for balers. Check all hoses and connections for leakage or wear and replace if necessary. Change the oil filter after the first 50 hours of operation and every 250 hours thereafter. Modify this schedule if the baler operates in hot, dusty conditions.
