Troubleshooting

PROBLEM

CAUSE

SOLUTION

Erratic or accelerated
pump speed.

Exhausted fluid supply.

Refill and prime.

Fluid is too heavy for pump priming.

Use the bleeder valve (see page 10); use a ram.

Held open or worn piston valve or seals. Clear the valve; replace the seals.

Held open or worn priming piston.

Clear; service.

Worn packings in the displacement
pump.

Replace the packings.
