Operating Instructions-- The TekMark Casing Spear attaches to the drill string or pipe joint. It has a release-position lock which can be activated before going down hole. This will allow you to run your drill string to the area where you wish to engage the pipe or screen. Once you are at the correct dept turn 80 to 100 psi of air on and then off. This will set the spear so you can pull the casing or screen. If for some reason you cannot pull the assembly then turn air on after taking the weight off the string. This will disengage the spear from the casing and then you can trip out of the hole by reapplying air after breaking each joint. Note: if you are under water you will have to apply 80 to 100 psi of air plus enough air to lift the water column in order to activate the spear. We recommend that you run the drill string wet when encountering water in the bore hole. If you are lowering the casing from the surface down the hole place the spear into casing and turn air on and then off to activate the spear and then lower the casing. Follow above instructions to relase the spear and return to the surface. The spear should be cleaned and dried after use. It is a good practice to lightly oil the surfaces of the tool to prevent rust.
