HOW TO SUCTION LOAD YOUR GREASE GUN:
A. Unscrew the head from the barrel. Pack head with grease.
B. Insert the open end of the barrel about 2 inches into the bulk grease. (see figure 6)
C. Slowly pull the rod handle while pushing the barrel deeper into the grease.
D. When the rod is fully extended, lock the rod into place. Remove the barrel from the grease.
E. Screw the head back onto the barrel.

F. Unlock the rod handle from the end cap.
G. If your grease gun has an air vent valve:
Depress the air valve as you push the rod handle into the barrel.
If your grease gun does not have an air vent valve:
Slightly loosen the head, then push the rod handle into the barrel. Retighten the head.
H. Pump the lever handle several times until grease flows from the coupler.
HOW TO BULK-LOAD YOUR GREASE GUN USING A PUMP:
This procedure applies only if your grease gun has a loader fitting or filler plug on the head. Models with
a filler plug will require a loader fitting that fits the valve on your pump. (Please note that there are
three industrial standard sizes for both fittings and valves).
A. Make sure the fitting is clean.
B. Push the rod all the way into the barrel.
C. Insert the loader fitting on the head into the valve on the pump (see figure 7).
D. Operate the pump until the barrel is full of grease. (The rod will be fully
extended).
E. Remove the loader fitting from the valve on the pump.
F. To prime the grease gun: Apply pressure to the rod handle by standing
the grease gun on a workbench and pulling down on the barrel while
pumping the lever handle at the same time (See figure 5). If your gun
has an air vent valve, press it; if not, slightly loosen the head as you pull
down on the barrel.
G. Pump the lever handle several times until grease flows from the coupler.
TROUBLE SHOOTING
Problem:
Gun will not dispense grease.
Possible Cause:
1.Grease cartridge or barrel may be empty.
Solution:
Replace the grease cartridge or refill the barrel with grease.
Possibly Cause:
2.Air is trapped in the head.
Solution:
Slightly loosen the head from the barrel. Push the rod handle to expel the trapped air, re-tighten the
head. (Or if your gun has an air vent valve, press it while pushing the rod handle).
