Filler Pump Filling From A Bulk Container; Purging Air Pockets - DeWalt DCGG571 Instruction 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 fill port FIG.9
(Z, Fig. 5) for attaching a low pressure fill
coupler onto the unit.
i_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.
ACAUTION: The fill pump loader must
connect correctly 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 (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 fill port plug
(AA) from the fill port.
4. Thread the appropriate low pressure
coupler onto the 1/8" NPT fill 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 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
8" (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 (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 refill 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 flexible hose (G)then depress the variable speed trigger
switch (A) for 10-20 seconds.
4. If grease fails to flow through the hose, repeat from step 1.
