Fill gun from bulk container

1 Remove pump assembly from grease tube
assembly.
2 Pack lubricant into cavity of the pump
assembly.
3 Insert the open end of the grease tube
assembly into lubricant. Slowly pull the
follower handle back while pushing the
grease tube assembly deeper into the
lubricant to prevent air pockets from being
pulled into the grease tube.
4 With the follower rod fully extended, pull it
sideways to latch the rod groove into the
slot in the grease tube assembly cap.
5 Loosely assemble the pump to the grease
tube assembly. Release the follower rod
from the grease tube assembly cap and
disengage the follower rod from the fol-
lower by rotating the follower handle.
6 Push the follower rod into the grease tube
assembly.
7 Unscrew the grease tube assembly from
the pump until lubricant oozes from the
interface. Tighten grease tube assembly
into the pump assembly.

Fill gun with filler pump

1 Engage the follower rod with the follower
by rotating the follower handle.
2 Insert the gun bulk fill valve into the filler
pump socket.
3 Operate the filler pump to fill the container.
When the follower rod groove is exposed,
the grease tube assembly is filled.
The follower rod will be extended approx-
imately 8 in. (20 cm). Do not overfill!
4 Disengage the follower rod from the fol-
lower by rotating the follower handle.
5 Push the follower rod into the grease tube
assembly.
note
Remove air pocket! Air pocket at grease
inlet prevents grease from being
pumped.
Unscrew vent valve three to four turns
to remove small air pockets trapped in
this area. If air pocket is substantial and
no grease flows from coupler after trig-
ger is pulled for 15 seconds, refer to
following steps.

Expel air pockets (air purging)

Fig. 2
1 Withdraw the follower rod from the grease
tube assembly cap and engage it with the
follower by rotating the follower handle.
2 Unscrew the plug of vent valve three to
four turns. Exert force on the follower
handle until grease flows through the
small hole in the side of the vent valve.
3 Tighten the vent valve.
4 Pull the trigger in short bursts to operate
gun until trapped air is expelled.
Disengage the follower rod from the
follower by rotating the follower handle.
Push the follower rod into the grease tube
assembly.
5 If step 2 fails, unscrew the grease tube
assembly three turns from the pump
assembly.
6 Exert force on the follower handle until
lubricant oozes from the grease tube
assembly and pump assembly interface.
7 Retighten grease tube into the pump
assembly. Disengage the follower rod from
the follower by rotating the follower han-
dle. Push the follower rod into the grease
tube assembly.
