Troubleshooting

3A6941J

The Pump is cycling, but there is no

lubricant output from the outlet. The

Pump lost priming/pump is

cavitating.

Tank was not refilled through the fill

port. Air in the tube-in-tube was

pushed into the grease tank.

Connect the refill pump to the fill

port and fill tank to remove any air.

Airlock inside of the pump.

Remove the pump outlet check

valve and o-ring (37). Connect the

refill pump to the fill port and fill the

tank to remove air. Run the

Compact Dyna-Star until lubricant

come out. Reassemble the outlet

check valve and o-ring (37).

Grease inside of the tank is not

moving to the pump shovel tube.

Install follower plate to help

distribute grease during pump

operation.

Follower plate is not moving and is

stuck inside of the tank.

Inspect and replace follower plate, if

necessary.

Follower plate is sunk into the tank. The grease viscosity is too low.

Remove the follower plate.

The pump element parts are worn or

damaged.

Replace with new pump element

parts.

Pump is cycling, there is output of

fluid at the outlet, but pump

pressure is not building.

Pump element parts are worn or

damaged.

Replace with new pump element

parts.

Vent valve is not energized in the

single line parallel system.

Check the wiring and correct.

Vent valve is energized but not

closing (leaky vent valve).

Open the inspection plug (AB), page

12, to confirm that the vent valve is

not closing (leaky). Replace the vent

valve.

Pressure relief is leaky.

Open the inspection plug (AB), page

12, to confirm pressure relief is

leaky. Replace pressure relief valve.

Pressure in the system not reduce

and the injectors are not reset.

The vent valve is not opened to vent

pressure.

Replace the vent valve.
