ASSEMBLY & INSTALLATION
GETTING READY TO USE THE AIR POWERED GREASE GUN
Select Follower Position
Note: Refer Figure 1 for correct follower position
HOW TO SELECT FOLLOWER POSITION
Air Supply: Dry air is needed to operate this gun. Make sure
FRL (Filter, Regulator, and Lubricator) unit is installed in airline.
Moisture in the air will damage the grease gun. The compressor
used must have a minimum volume of 1 CFM (0.026 cubic meter).
Inlet air supply should have a pressure between 40 - 120 PSI (3–8
BAR). The recommended working pressure is 90 PSI (6 BAR).
This grease gun has a 40:1 pressure ratio; i.e. the grease discharge
pressure will be 40 times the inlet air pressure.
Lubrication: Like all air equipment, this grease gun needs regular
lubrication. To lubricate, add a few drops of oil through the air
inlet on the grease gun. It is recommended to use SAE 30 or
higher viscosity oil.
Connecting the grease gun to air supply: There are several types
of quick connect couplers available in the market. This grease
gun comes with one standard male quick connect coupler. The
coupler must fit properly onto the female quick connect coupler
on the airline. If it does not fit properly, use a coupler that does.
Operating the grease gun trigger: This is a one shot grease gun,
whereby there is grease discharge with every press of the trigger.
Do not keep the trigger pressed during operation. The trigger
must be repeatedly pressed and released while greasing. Also, do
not repeat the action too fast, as the piston needs to complete a
full cycle before starting a new one.
SETTING UP THE GREASE GUN HEAD
Attach the male quick connect coupler air fitting supplied with
the gun onto the air inlet on the die cast handle. The male quick
connect coupler air fitting has ¼” NPT threads and should be
threaded into the female hole on the die cast handle using thread
sealant. Make sure the connection is tight so that there is no
leakage of air. Use PTFE Tape while connecting the air fitting to
the air inlet.
CAUTION
Grease or empty cartridge in barrel is under pressure from the
internal spring, use caution when removing either end of the
barrel.
LOADING GREASE GUN
Removing empty Grease Cartridges
1. Pull back the plunger handle to its maximum extended
position and lock it in place .
2. Unthread the grease gun head from barrel assembly by
turning it counter clockwise.
3. Remove any empty cartridge from the barrel.
INSTALLING GREASE CARTRIDGES
NOTE: Choose the correct follower position (see figure 1)
1. Make sure the gun is disconnected from the air supply. Pull
back the follower rod all the way to the end of the barrel &
lock it so that the grease cartridge can be fully inserted.
2. Unthread grease gun head from barrel assembly.
3. Remove the plastic cap from the grease cartridge and insert
the open end of the cartridge into the grease gun barrel until
the rim of the pull-tab end meets the rim of the grease gun
barrel.
4. Remove the pull-tab seal from top of the cartridge and screw
tighten the head onto the barrel while keeping at least 2-3
turns open before the barrel is fully tightened.
5. Unlock the plunger rod handle from the end cap.
6. Move the plunger rod forward and backward to remove any
trapped air pockets.
7. Connect the air supply and prime the gun by operating the
gun by pressing and releasing the trigger until the grease
starts coming out of the discharge nozzle.
8. Initial grease discharge may have trapped air. Once the gun
has been primed, fully tighten the grease gun head onto the
barrel.
9. Push the plunger rod into the barrel for easier maneuverability
during use.
10. Connect the grease gun extension and coupler onto the
grease gun outlet and it is advisable to use a thread sealant to
ensure a leak-proof connection between joints.
NOTE
Do not apply excessive torque or over-tighten the grease gun
extension as this will apply undue stress to the die cast outlet
and may cause it to fracture.
TO CONVERT GUN TO ALLOW FILLING FROM BULK
CONTAINER OR FILLER PUMP
1. Unthread the barrel cap from barrel assembly and pull out the
follower and spring from barrel.
2. Hold Follower between thumb and fore finger to flip the
follower lip from rear to the front side.
NOTE
Always remove any cartridges from the grease gun prior to bulk
filling.
3. Put follower back into barrel and thread tighten the barrel cap
& follower assembly with the barrel.

LOADING GREASE GUN USING BULK GREASE
1. Make sure the gun is disconnected from the air supply. Pull
back the plunger rod handle all the way to the end of the
barrel & lock it.
2. Remove head assembly of grease gun by rotating it in
counter- clockwise direction. Release plunger handle and
allow the handle to move to its most forward position.
3. Insert the open end of the barrel into the grease.
4. Slowly pull the plunger rod handle while pushing the barrel
deep into the grease until the plunger rod is all the way
extended.
5. The grease gun barrel should now be filled with grease. Wipe
the grease from outside surface of barrel before use.
6. Screw the head of the gun onto the barrel, but do not fully
tighten the barrel. For now leave at least 2-3 turns before the
barrel is fully tightened.
7. Unlock the plunger rod handle from the end cap.
8. Move the plunger rod forward and backward to force out any
trapped air pockets from the connection between the grease
gun head and the barrel, which is not fully tightened.
9. Connect the air supply and prime the gun by operating the
gun by pressing and releasing the trigger until the grease
starts coming out of the discharge nozzle.
10. Initial grease discharge may have trapped air. Once the gun
has been primed, fully tighten the grease gun head onto the
barrel.
11. Push the plunger rod into the barrel for easier
maneuverability during use.
12. Connect the grease gun extension and coupler onto the
grease gun outlet and it is advisable to use a thread sealant
to ensure a leak- proof connection between joints.
NOTE
Do not apply excessive torque or over-tighten the grease gun
extension as this will apply undue stress to the die cast outlet
and may cause it to fracture.
LOADING GREASE GUN USING A FILLER PUMP: (FOR MODELS
FITTED WITH BULK LOADER VALVE ON GREASE GUN HEAD)
1. Wipe the grease gun’s bulk loader clean.
2. Connect the grease gun’s bulk loader valve to the bulk loader
adapter on the filler pump.
3. Start Operating the pump to fill grease into the barrel. Do not

extension as this will apply undue stress to the die cast outlet
and may cause it to fracture.
GREASING A GREASE FITTING / GREASE NIPPLE
The grease coupler provided at the end of the grease gun
extension has a jaw type construction. The coupler jaws will snap
on to a grease fitting and maintain a tight fit. When connecting
the coupler to the grease fitting, press the coupler straight onto
the grease fitting to form a snug fit. Start operating the grease
gun with the coupler as square to the grease fitting as possible.
Once greasing is completed, slightly tilt the coupler, twist and
pull back. The tilt and twist action will allow easy removal of the
coupler from the grease fitting.
MAINTENANCE
Grease guns and hoses should be kept clean and checked
for damage before each use. Use an air supply system that
incorporates a filter, regulator, and lubricator, or add a few drops
of lubricator oil (SAE 30 or greater) through the gun’s air supply
quick connect fitting in the die cast handle.
