DeWalt DCGG571 Manual page 45

IMPORTANT: The grease gun will lose its prime if
there are air pockets in the lubricant.
Removing Empty Grease Cartridge
(fi g. 1)
1. 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.
2. Unscrew the grease tube assembly (n) from the
grease gun and remove.
3. Gently release the grease tube handle (l) to
expel the empty cartridge from the grease tube.
Filling the Grease Gun from a Bulk
Container (fi g. 1, 8–10)
PREPARING THE GREASE GUN FOR SUCTION AND FILLER
PUMP FILLING (FIG. 1, 8)
NOTE: Be sure the grease gun is empty of grease
before beginning this process.
1. Unscrew the grease tube (j) from the grease gun
assembly (n).
2. Unscrew the grease tube cap (k) from the
grease tube (j) and pull out the grease rod (m).
3. Using your thumb and forefinger, flip the rubber
seal (gg) from the rear to the front. Refer to
Figure 8.
NOTE: The seal resembles a cup, which should
open toward the top cap (f, fig. 1) when prepared for
suction and filler pump filling.
4. Reinsert the grease tube rod (m) back into the
grease tube (j).
SUCTION FILLING FROM A BULK CONTAINER
(FIG. 1, 5, 7, 9)
1. Put the open end of the grease tube assembly
into the bulk lubricant.
2. Slowly pull back the grease tube handle (l) to
suction the lubricant into the grease gun.
NOTE: Be sure to keep the open end of the grease
tube assembly far enough into the lubricant to
prevent air pockets in the grease tube.
3. When the grease tube rod (m) is fully extended,
secure it into the retaining slot (o)
4. Remove the grease gun tube assembly from the
bulk lubricant and wipe off excess grease.
5. Screw the grease gun tube assembly (n) back
into the grease gun.
6. Release the grease tube rod (m) from the
retaining slot (o) and slowly press it back into
the tube.
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. 1, 5, 7, 9)
This tool comes with a 1/8" NPT fill port (z, fig. 5) for
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 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. 1, 10)
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.
