TROUBLESHOOTING GUIDE
Plunger Lubrication
To maintain the maximum performance of the air tool, it must be lubricated
each time it is used. Dust, dirt, rust and oil residue will build up inside the tool
and reduce the performance. An in-line oiler is recommended for proper auto-
matic lubrication (see Figure 1). If an in-line oiler is not available, the tool can be
lubricated manually through the inlet port (see Figure 7).
1. Disconnect the air tool from the air supply.
2. Turn the tool upside down and while depressing the trigger, add 1-2 drops
of air tool oil or SAE10 nondetergent oil into the air inlet.
NOTE:
Depressing the trigger helps circulate oil on the plunger within the
grease gun head.
3. Reconnect the tool to the air supply.

Figure 5
a. Pull the plunger handle on the container tube completely out.
b. Put the filler plug into the filler pump socket.
c. Fill the container tube by pumping the filler pump handle (see filler
pump instruction manual for instructions).
d. Disconnect the container tube filler plug from the filler pump socket.
e. Press the handle release to release the plunger handle.
f. Push the plunger handle all the way in while pressing the handle
release.
g. Press the air vent valve to release any excess air trapped inside.

a. Remove the head of the grease gun from the container tube.
Figure 6
b. Pull the plunger handle on the container tube completely out.
c. Fill the container tube with bulk grease.
d. Reassemble the head of the grease gun to the container tube.
e. Press the handle release to release the plunger handle.
f. Push the plunger handle all the way in while pressing the handle release.
g. Press the air vent valve to release any excess air trapped inside.
7. Connect the tool to the air hose quick coupler.
NOTE: It is recommended that a whip hose with a swivel
(P012-0079SP - not included) be used to prevent twisting, kinking and excessive wear to the air
hose (ref. item “F” in figure 1 for recommended connections).
8.
Depress the trigger completely to operate the grease gun (the grease is applied in shots, not in a continous
flow).
9. Release the trigger to stop the tool.
SYMPTOM
POSSIBLE CAUSE(S) CORRECTIVE ACTION
Grease gun fails to
work or is slow
Air pockets in the gun Draw back the plunger handle fully and release by pressing the
handle release. Repeat several times. This will help exert force to
move the rubber ring into the cartridge tube, which is essential for
the grease gun to work. Push the plunger handle all the way in.
Press the air vent valve several times to free the air.
Air hose leaks
Tighten and seal hose fittings with Teflon® tape if leaks are found.
Low air pressure
Adjust compressor regulator to 90 PSI.
Plunger is sticking
Lubricate plunger (see “user maintenance” section).
Remove the head of the grease from the container tube. Connect to
an air hose. Using a small screwdriver, insert it into the end of the
nozzle and press the trigger a few times until the plunger clicks and
moves in and out.
Cartridge is empty
Refill the container tube
Grease gun is too cold The grease gun needs to be at room temperature (65° - 80° F).
