BATTERY CHARGER SAFETY INFORMATION
1. A battery operated tool with internal batteries or a separate battery pack must only be
powered by the included battery. Do not, for instance, mix different brands of tools and
batteries or use adapters to allow you to use a battery pack with a different voltage. Using
another battery pack could cause a fire.
2. Batteries must only be recharged with the included charger. A charger that may be suitable
for one type of battery could cause a fire when used with another battery.
3.Setthetool’striggerswitchtotheOFFpositionbeforeinstallingorremovingthebatterypack.
This will prevent injury due to accidental starts.
4. Do not use the battery charger in damp or wet locations.
5. Do not store battery packs in containers / spaces with loose metal objects. Battery pack
terminals could be short circuited if they come into contact with metal objects. In addition to
damaging the battery pack, you increase the risk of a fire.
NOTICE: Before using your tool for the first time, discharge the battery and then charge the
battery pack completely.
WARNING! Never burn batteries, as they can explode in a fire. Do not charge leaking batteries.
Only a qualified service technician should perform maintenance on the battery pack. Contact local
solid waste authorities for instructions on correct disposal or recycling of the battery pack.
WARNING: Do not use the tool if the trigger does not function properly. Any tool that cannot
be controlled with the ON / OFF switch is dangerous and must be repaired.
1. Use the correct tool for the job. Maximize tool performance and safety by using the tool for its
intended task.
2. Do not modify this tool or use for a purpose for which it was not designed.
3. This tool was designed for a specific function.
DO NOT:
a. Modify or alter the tool; all parts and accessories are designed with built-it safety features that
may be compromised if altered.
b. Use the tool in a way for which it was not designed.
UNPACKING
1. Carefully remove the tool from the package.
2. Retain packing material until you have carefully inspected and satisfactorily installed or
operated the tool.
3. Inspect the parts carefully to make sure the tool was not damaged while shipping.
CHARGER OPERATION
1. Insert the battery pack into the charging socket of the charger. Then, plug the charger into the
nearest grounded, electrical outlet. The battery is charging when the green light is illuminated
and the red light goes out.
NOTICE:
Make sure the power circuit voltage is the same as that shown on the charger
specifications plate.
2. Before using the grease gun for the first time, be sure to discharge the new battery before
charging. All new rechargeable batteries come with 80% charge from the factory. If the
battery pack is installed in the gun, remove it by depressing the two battery release buttons
(one button on each side of the battery pack) and pull the battery pack out of the gun.
3. As a battery pack approaches the discharged state, you will notice a sharp drop in tool
performance. When the tool is unable to perform the task at hand, it is time to recharge the
battery pack. Recharging the battery pack before this condition is reached will reduce the
total work life of the pack. Discharging the pack beyond this point can damage the pack.
4. Start the charging process by plugging in the battery charger to the power source and
inserting the battery into the battery charger slot. After the charging process is complete
(approximately 1 hour), the green light will go out and the red light will illuminate. Remove the
charger from the wall outlet and disconnect the battery pack.
NOTICE:
Battery temperatures will increase during and shortly after use. Batteries may not
accept a full charge if they are charged immediately after use. Allow the battery pack to cool to
room temperature before charging for the best results.
INSTALLING GREASE CARTRIDGE
1. Depress the follower key and pull back on the follower handle. Until the follower rod is fully
extended (approximately 8 in. or 20 cm).
NOTICE: It may be necessary to loosen the grease tube assembly in order to break the vacuum seal.
2. Identify the style grease cartridge you have, paper or plastic. One end will have a replaceable
cap that exposes the grease. The other end will have a pull tab or foil seal
3. Remove the replaceable cap from the end of the grease cartridge. Insert that end into the
grease gun barrel. It should rest on the rubber plunger at the bottom of the barrel.
4. Remove the pull tab or foil from the exposed end of the cartridge.
5. Depress the follower key and push the follower rod forward into the grease tube assembly.
Purge the air from the head.
CARE AND MAINTENANCE

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.
