Use and Care Manual

7. Use the purge valve (X, Fig. 5) to bleed off any air that may be
trapped in the cartridge. Refer to Purging Air Pockets.
FILLER PUMP FILLING FROM A BULK CONTAINER
(FIG. 5, 6, 9)
This tool comes with a 1/8" NPT fi ll port
FIG. 9
(Z, Fig. 5) for attaching a low pressure fi ll
coupler onto the unit.
WARNING: Never thread a high-
pressure coupler onto the grease
gun’s 1/8" NPT fi ll port. Serious injury
may occur due to excessive pressure.
Use low-pressure couplers only.
CAUTION: The fi ll pump loader must
connect correctly with the grease gun’s
1/8" NPT port. The fi ller 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 (N)
back into the grease gun and screw it
in securely.
2. Pull the grease tube handle (L) out as
far as it will go, then secure the grease
tube rod (M) into the retaining slot (O)
by 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 fi ll port plug
(AA) from the fi ll port.
4. Thread the appropriate low pressure
coupler onto the 1/8" NPT fi ll port (Z).
5. Release the grease tube rod (M) from the retaining slot (O) and
slowly press it back into the tube.
6. Use the purge valve (X) to bleed off any air that may be trapped in
the cartridge. Refer to Purging Air Pockets.
FILLING THE TOOL FROM THE LOW PRESSURE FILLER
PUMP (FIG. 2, 9)
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 (O).
2. Connect the low pressure fi tting on the grease gun to the
appropriate low pressure fi tting on the fi ller pump. These fi ttings
DO NOT lock together. This prevents the grease gun cartridge
from being over fi lled.
3. Fill until the rod is pushed out of the grease tube approximately
8" (20cm). Do not overfi ll. If the rod fails to move during the fi lling
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 (X) to bleed off any air that may be trapped in
the cartridge. Refer to Purging Air Pockets.
Purging Air Pockets (Fig. 2, 5)
IMPORTANT: Air pockets in the grease can cause the grease gun to
lose prime. Eliminate air pockets after each refi ll or if the grease gun
fails to pump grease:
1. Unscrew the purge valve (X) without removing it, until all air has
escaped.
2. Tighten the purge valve (X).
3. Uncap the fl exible hose (G) then depress the variable speed trigger
switch (A) for 10–20 seconds.
4. If grease fails to fl ow through the hose, repeat from step 1.
