- 8 -
Grease filling options:
1) Cartridge Loading: Remove the plastic cap from the 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 barrel.
2) Suction Fill: Insert the open end of the barrel about 2” into the grease
container.Slowly pull the plunger rod handle to draw in grease into the
empty barrel while pushing the barrel deeper into the grease until the
plunger rod is completely extended.The outside surface may have a lot of
grease stuck to it and should be wiped clean for safety.

Step3：Assemble the barrel back into the grease gun.Activate the
safety catch and push the push rod back into the Barrel.
Step4：Exhaust air by pressing the air release valve or loosening the gun
head and barrel (half a turn maximum).

Step6：Attach the male quick connect coupler air fitting supplied with
the gun onto the air inlet. Make sure the connection is tight so that there is
no leakage of air.Press the trigger repeatedly for grease filling.
NOTE:
The male quick connect coupler air fitting has 1/8” NPT threads.
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.Inlet air supply should have
a pressure between 0.6~0.8 M pa.
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.
