be trapped in the cartridge. Refer to Purging Air Pockets.
IMPORTanT: The grease gun will lose its prime if there are air
pockets in the lubricant.
Removing Empty Grease Cartridge (Fig. A)
1. Pull the grease tube handle
secure the grease tube rod
moving the rod to the side. Ensure the rod is placed securely

Suction Filling from a Bulk Container
(Fig. A, E, G, I)
1. Put the open end of the grease tube assembly into the
bulk lubricant.
2. Slowly pull back the grease tube handle
lubricant into the grease gun.
nOTE: Be sure to keep the open end of the grease tube

Filler Pump Filling From a Bulk Container
(Fig. A, E, G, I)
This tool comes with a 1/8" NPT fill port (
attaching a low pressure fill coupler onto the unit.

WARNING: Never thread a high-pressure coupler
onto the grease gun's 1/8" NPT fill port. Serious injury
may occur due to excessive pressure. Use low-pressure
couplers only.

CAUTION: The fill pump loader must connect correctly
by
with the grease gun's 1/8" NPT port. The filler pump may
not operate if the components are not compatible.
Installing The Low Pressure coupler (not supplied With
The Tool)
1. Thread the grease tube assembly
gun and screw it in securely.
2. Pull the grease tube handle
secure the grease tube rod
moving the rod to the side. Ensure the rod is placed securely
in the slot to prevent it from disengaging.
3. Remove the 1/8" NPT fill port plug
4. Thread the appropriate low pressure coupler onto the 1/8"
NPT fill port 26 .
5. Release the grease tube rod
and slowly press it back into the tube.
6. Use the purge valve
trapped in the cartridge. Refer to Purging Air Pockets.
Filling The Tool From The Low Pressure Filler Pump
(Fig. a, J)
1. Pull back on the grease tube handle slowly and rotate the
rod until it is secure in place.
nOTE: Do not lock the rod into the retaining slot
2. Connect the low pressure fitting on the grease gun to the
appropriate low pressure fitting on the filler pump. These
fittings DO NOT lock together. This prevents the grease gun
cartridge from being over filled.
3. Fill until the rod is pushed out of the grease tube
approximately 20 cm. Do not overfill. If the rod fails to move
during the filling process, stop. This indicates that the rod
is not connected to the plunger and step one must be
repeated before proceeding.
4. Rotate rod to release and carefully push rod back into the
grease tube.
5. Use the purge valve
trapped in the cartridge. Refer to Purging Air Pockets.
Purging Air Pockets (Fig. A, E)
IMPORTanT: Air pockets in the grease can cause the grease
gun to lose prime. Eliminate air pockets after each refill or if the
grease gun fails to pump grease:
1. Unscrew the purge valve
air has escaped.
2. Tighten the purge valve
