OPERATING INSTRUCTIONS

Step1: Hold the head of the grease gun and unscrew the barrel.
Take LD-2710 as an example.

Step2: 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.

Grease Gun Filling Device: Place the grease gun onto the filling valve of the grease gun filling unit, and hold it in place with light counter pressure.
Fill the grease gun by activating the filling device.

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) or by repeatedly actuating the handle.
Step5: Install the required fittings as required as shown below.(Fig 1,Fig 2, Fig 3)
Note: If necessary, wrap 3~5 loops of raw material tape around the joint.

Step6: 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.

Above are the LD-2710 operations. The operations of the LD-868 LD-867A,LD-867B are the same as that of LD-2710.
