Troubleshooting
Problem:
Grease gun runs obstructive.
Possible cause:
Lack of oil in air motor.
Solution:
Fill a few drops of oil through the air inlet and let the unit run
for a few minutes.
Problem:
Gun runs at normal speed but grease does not escape.
Possible cause:
Air pockets are inside the container tube.
Solution:
Unscrew the container tube (B) with 1 or 2 turns from the head
(H) of the gun and execute the following steps:
Fully draw back the plunger handle (C) and release quickly by
pressing the catch plate (I). Repeat this several times. This
way the plunger will push out the waste air which is essential
for the grease gun to work.
Push the plunger handle (C) all the way in.
Tighten the container tube to the gun head.
Repeat those steps if necessary.
Problem:
Grease gun runs slowly or does not run well.
Possible cause:
Air motor is jammed with dirt particles. Air flow blocked by dirt.
Solution:
Check the air and grease inlets for blockage.
Check the proper connection between the air fitting of the
compressor and the air fitting of the grease gun.
Problem:
Plunger does not enter the grease cartridge.
Possible cause:
The size of the cartridge does not correspond to the standard
sizes. The opening of the cartridge is rough or irregular.
Solution:
Check the size and dimensions of the cartridge.
Grease the surface of plunger and opening of the cartridge.
Always use standard size cartridges.
Check the opening of the cartridge for damage. It should be
clean and exactly round. Otherwise the plunger rubber can not
enter the grease cartridge and the grease can not be pushed
out.
Do not re-use empty grease cartridges. Remove a used car-
tridge from the container tube when manually bulk loading
grease.
