(2) If air leaks where the actuator is screwed into the tube, the gasket between the grease gun and the actuator
may be worn. Reverse or replace the gasket.
(3) If air leaks into the grease, disassemble the grease gun and remove the slider assembly, which is the
leather cup assembly at the end of the pull rod. It is possible that the slider 0 ring or leather cups may be
dry or worn. Lubricate these items as described in a above. If the air leak continues, replace the leather
cups and slider O ring.
(4) If the air line coupler should leak, it is possible that the valve seat is worn. Disassemble the air line coupler,
and replace the valve seat.
c. Correcting for Insufficient Dispensing. If the actuator operates, but insufficient material is dispensed, these
possible causes and remedies are suggested: Check the supply' of lubricant within the grease gun. If lubricant supply is
exhausted, refill the grease gun as instructed in paragraph 169. Do not operate the actuator trigger too rapidly. Follow the
operating instructions carefully as outlined in paragraph 169c. Inspect the nozzle adapters or dispensing adapters
carefully for signs of clogging. If necessary, remove, disassemble and thoroughly clean these parts with cleaning solvent.
Dry with compressed air, and reassemble the adapters.
d. Preparing for Storage.
(1) Flush the grease gun and adapters which have been used with cleaning solvent to remove all grease from
the equipment. Then blow these parts dry with compressed air.
(2) Place the grease guns and accessories in their appropriate places within the grease gun kit box as shown in
figure 70. Close and lock the grease kit box and place the box in its appropriate position in the compressor
front tool box.
