Step 1 Hold the head of the grease gun and unscrew the barrel.
Step 2 Pull back the plunger rod handle and fill the barrel with grease.
Grease filling options:
-
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.
-
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.
Step 3 Assemble the barrel back into the grease gun.Activate the safety
catch and push the push rod back into the Barrel.
Step 4 Exhaust air by pressing the air release valve or loosening the gun
head and barrel (half a turn maximum).
Step 5 Install the required fittings as required as shown below. (Fig
1,Fig 2)
Note: If necessary, wrap 3~5 loops of raw material tape around the joint.
Step 6 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.
Step 7: Press the coupler straight onto the grease fitting,Start
operating the handle for grease filling.
Once greasing is done, slightly tilt the coupler, twist and pull back. The
tilt and twist action will allow easy removal of the coupler from the grease
fitting.
