Instruction for Assembly of ATD-5286 Bulk filled Lubrigun
Unpack ATD-5286 Assembly from
Carton This should include the following pieces: Pump, Drum Cover (Red),
Follower Plate, Grease Control Valve, 6 Foot Grease Hose, Muffler, Air
Nipple and Rapid Disconnect Coupler and Container
Assemble Drum Cover to Pump In mose cases your pump has been preassembled and tested.
Fill Container with Lubricant This is a bulk filled unit. You can fill container 91117ME.
Unit comes ready to use with Minimal assembly required.; Release cover clamps (3) and remove the pump
/ cover assembly from the container. Ensure Follower Plate is not left in the container at the bottom.
Fill Container 91117ME with Lubricant (Grease); Ensure Follower plate is on the Downtube and not in the
container BEFORE putting filling the container with grease. (Please Read Again)
Mount cover / pump assembly with downtube onto the container filled with grease. Apply slight
pressure on the follower plate to remove air pockets.
Assemble the lubricant hose to the pump outlet body. The connections must be leakproof. Do not connect the ATD-
5218 Control Valve Yet. If it is connected, you might want to disconnect it . You want to prime the system and
purge contaminants out of the Grease Hose.
The Air Nipple 11660 has already been inserted and threaded into pump head opening. Use Teflon tape to seal threads
to prevent air leakage if necessary.
Assemble air coupler 815ME to an air hose of sufficient length so that the lubrigun can be moved to cover the
entire lubrication area with the hose attached. When air coupler 815ME is attached to air coupler nipple
11660, lubrigun is ready for operation. To release air coupler 815ME, draw back on the coupler sleeve.
DID YOU: Purchase a Filter / Regulator for your pump? The Filter / Regulator should have an
automatic dump mechanism to purge the water out of the incoming air. Water in
the compressed air system is the biggest “Killer” of Air Operated Equipment.
YES: Proceed
NO: Think about it! It is cheap insurance to keep your pump running at maximum
efficiency and the pump will last longer.
Initiating Air Motor and Pump Operation
To Start Pump: Turn on air from Air Regulator slowly. You will hear the air enter the air motor. Pump will
start quickly and then reach prime at a stall pressure. It might take as much as 60-70 PSI to get the pump
started initially. Recommended Air Pressure to operate the pump under normal conditions is 80PSI. Pump
will activate as low as 15-20PSI. For first time operation, pump will start at 50-60 PSI. After that pump will
activate at the lower pressure.
Pump will start quickly and then reach prime at a stall pressure when the control valve is attached.
Allow pump to operate: Pumping Grease into the hose. Allow approximately 1/3 Cup of Grease to flow out
of the Hose. This is to insure that any particles or contaminants or residue inside the hose do not enter
the ATD-5218 Control Valve. Stop Pump; Install the ATD-5218 Control Valve on the hose; Make sure
connections are tight; Resume operation of the pump. The pump should reach stall pressure and stop.
Test the System Pull the Trigger slowly and Grease should be ejected from the nozzle. Don’t point it
at anyone!
Never Put your Finger or Other Bodily parts near the valve control nozzle when pulling the trigger on the control valve
ATD-5218ME.
To know the amount of lubricant pressure in your system or the hose, multiply the amount of air pressure by
50. For example, if there are 100 psi of air pressure indicated on the regulator (100 psi of air entering) then
there are 5000 psi of grease pressure in the lubricant line.
This checklist was done at the factory:
Ensure that the Muffler ATD-5317 is inserted in the correct orifice.
The Lube Hose ATD-5361 has been connected to the pump. If you desire a longer hose, simply replace hose
and use Teflon tape to seal the threads. Connect ATD-5218 Control Valve to Hose.
Have you thought of a Grease Strainer for the Pump Down Tube: 99% of Pump Repairs are due to Foreign
Particles caught in the Down Tube. Ask for Strainer ATD-5356
