PowerLuber Grease Gun
Installing Grease Cartridge
1. Unscrew the grease tube assembly from the PowerLuber.
2. Visually check the follower seal lip direction before load­
ing a new cartridge. The follower seal lip must be directed
toward the follower handle or rear side for cartridge loading.
See Fig. 2. (To change the direction of the follower seal,
unscrew tube cap from grease tube assembly and pull on
the handle to remove follower seal from tube. Flip follower
seal over and reassemble.)
3. Pull back on the follower handle and latch the follower rod
groove into the slot on the tube cap.
4. Remove the plastic cap from the grease cartridge and
insert cartridge into the container tube.
5. Remove the pull tab from grease cartridge and screw
grease tube assembly into pump assembly.
6. Release follower rod from slot. Purge air from pump. See
air purging instructions.
Air pockets in the cartridge lubricant will cause the gun to
lose its prime.
Removing Empty Grease Cartridge
1. Pull back on the follower handle until the follower rod is fully
extended and latch the follower rod groove into the slot on
the tube cap.
2. Unscrew the grease tube assembly from the PowerLuber.
3. Carefully release the follower handle to eject the empty
cartridge from container tube.
To Convert Gun to Allow Filling From Bulk
Container or Filler Pump
1. Unscrew the grease tube assembly cap from the grease
tube assembly. Pull on the follower handle to extract the

NOTE: The follower resembles a cup. When the gun is as­
sembled for use with bulk lubricant, the cup opens toward
the pump assembly.
3. Reassemble follower into grease tube assembly and posi­
tion with the follower handle so that the grease tube assem­
bly cap can be tightened onto the container tube.

To Fill The 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 lubri­
cant (see Fig. 3). 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 assembly.
4. When the follower rod is fully extended, pull it sideways to
latch the rod groove into the keyhole slot in the grease tube
assembly cap.
5. Loosely assemble the pump assembly 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. Push the follower rod
into the grease tube assembly. Slowly unscrew the grease
tube assembly from the pump assembly until lubricant
oozes from the interface. Tighten grease tube assembly
into the pump assembly.
To Fill The Gun with a Filler Pump
1. Engage the follower rod with the follower by rotating the fol­
lower handle.
