TO CONVERT THE 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 follower and spring from the grease tube assembly.
2. Grasp the follower between your thumb and forefinger and flip the follower lip from the rear
to the front side.
NOTICE: The follower resembles a cup. When the gun is assembled for use with bulk lubricant, the
cup opens toward the pump assembly.
3. Reassemble the follower into the grease tube assembly and position with the follower handle
so that the grease tube assembly cap can be tightened onto the container tube.
TO FILL THE GUN FROM A BULK CONTAINER
1. Rotate the grease tube assembly counterclockwise to unscrew the grease tube assembly
from the gun.
2. Insert the open end of the grease tube assembly into the 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 assembly.
3. When the follower rod is fully extended (approximately 8 in. or 20 cm), the grease tube
assembly is full. Release the follower key to hold the follower rod in its extended position.
4. Screw the grease tube assembly clockwise into the gun. To release the follower rod, depress
the follower key and push the follower rod forward into the grease tube assembly. Purge the
air from the pump. See the section To Re-prime.
5. Clean any excess grease from the gun body.
TO FILL THE GUN WITH A FILLER PUMP
A bulk filler fitting (sold separately) will need to be installed in the grease gun head cap.
Replace the pipe plug in the head cap with the bulk loader fitting. Engage the follower rod
with the follower by rotating the follower handle. Insert the gun filler nipple into the fill pump
socket. 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 approximately 8 inches
(20 cm). Disengage the follower rod from the follower by rotating the follower handle. Push
the follower rod into the grease tube assembly.
1. Fully insert the charged battery pack into the grease gun.
2. Connect the high-pressure hose coupler to the grease fitting, and ensure that the coupler is
squarely seated on the fitting.
3. Squeeze the trigger switch to activate the grease gun. Grease should now be dispensed
through the high-pressure hose coupler and into the grease fitting.
4. When you have finished applying grease, remove the high-pressure hose coupler from the
grease fitting by pulling it sideways.
WARNING! Do not adjust the pressure relief valve. If back pressure in the high-pressure hose
exceeds the factory’s preset pressure rating, grease will be discharged through the pressure relief valve
to prevent motor overload and to limit grease pressure within the hose.
REMOVING EMPTY GREASE CARTRIDGE
1. Pull back on the follower handle until the follower rod is fully extended.
NOTICE: It may be necessary to loosen the grease barrel assembly in order to break the vacuum seal.
2. Unscrew the grease barrel assembly from the head of the grease gun.
3. Carefully pull the spent grease cartridge from the barrel and replace it with a full cartridge to
complete your project.
4. Screw the grease barrel back onto the head. Depress the follower key and push the follower
rod forward into the grease barrel assembly. Purge the air from the head.

OPERATION
TO RE-PRIME
NOTICE: If the gun loses its prime, it is usually due to air pockets in the lubricant.
1. Withdraw the follower rod from the grease barrel assembly, and firmly push the follower rod
back into the grease barrel assembly.
2. Squeeze the trigger switch in short bursts until all air pockets are expelled.
3. If step 2 fails to re-prime the gun, unscrew the grease barrel assembly 1-1/2 turns.
4. Push the follower handle into the grease barrel assembly until lubricant is released from the
grease barrel assembly at the point where it screws into the pump housing.
5. Tighten the grease barrel assembly and remove excess grease from the exterior of the gun.
OPERATION
MAINTENANCE
1. Make sure the trigger switch is in the OFF position, the battery is removed from the grease
gun, and the charger is unplugged from the electrical outlet before performing any
inspection, maintenance, or cleaning.
2. Check the general condition of the grease gun before each use. Check for misaligned or
binding moving parts, cracked or broken parts, leaking battery packs, damaged hoses, and
any other conditions that may affect the safe operation of the grease gun. If abnormal noise
or vibration occurs, have the problem corrected before further use. Do not use damaged
equipment. Replace worn parts.
3. Daily maintenance: Use a soft, dry cloth to remove all dirt, grease, and debris from the
exterior of the grease gun. Do not use solvents to clean the grease gun.
4. Use only identical replacement parts when servicing. Only use accessories that are intended
for use with this tool.
5. If repairs are required, bring your tool to an authorized service centre.
STORAGE
When storing, always remove the battery pack from the grease gun. Keep the grease gun and
its accessories in a clean, dry location and out of the reach of children.
DISPOSING OF THE TOOL
1. If your tool has become damaged beyond repair, do not throw it out. Take it to the
appropriate recycling facility.
2. Do not incinerate battery packs. Battery packs may explode when exposed to high heat.
