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

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.

FILLER PUMP FILLING FROM A BULK CONTAINER
(FIG. 5, 6, 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).
