Depending on the type of pump, it is often best to check for leaks by using a hand pump and applying pressure to the
suspect area without the motor running. Watch for leaking oil and follow it back to its source. (This will not work on an
automatic valve pump, because there won't be any pilot pressure to close the valve.) If there is a crack in the pump
housing, oil can leak into the gear housing and be difficult to find. Always plug the outlet ports of the pump to
eliminate the tool or cylinder as the cause of the leakage.
PROBLEM
Motor does not run
Motor hums but does not rotate
Hydraulic oil leaking into gear
case under motor
Pump is not delivering oil
TROUBLE-SHOOTING GUIDE
CAUSE
1. Pump turned OFF.
2. Pump unplugged.
3. No voltage supply.
4. Broken lead wire or defective
power cord plug.
5. Defective remote switch.
6. Worn brushes.
7. Defective motor.
1. Broken gear has jammed power
train.
1. Damaged oil shaft seal and/or
o-ring seal.
2. Crack in pump body.
1. Oil level too low.
2. Pump is not primed.
3. Loose fitting coupler to cylinder.
4. Vacuum in reservoir.
5. Air in system.
6. Air leak in suction line.
7. Dirt in pump or filter plugged.
8. Oil bypassing through valve or
cylinder.
9. Cold oil or oil is too heavy (of a
higher viscosity than necessary)

1. Turn toggle switch ON.
2. Plug in pump.
3. Check line voltage.
4. Replace defective parts.
5. Check remote switch.
6. Replace brushes.
7. Replace defective parts.
1. Replace broken gear and correct
condition that caused failure.
1. Replace damaged seal(s).
2. Replace pump body.
1. Retract cylinders. Fill reservoir to
1/2" from top of filler hole.
2. Open priming screw - follow
instructions.
3. See if quick disconnect couplings
to cylinders are completely
coupled. Sometimes couplers
have to be replaced, because
the ball check doesn't stay open
due to wear.
4. Open filler plug two turns.
5. Bleed the system.
6. Tighten suction line.
7. Clean filter. Dismantle pump and
clean all parts, if needed.
8. Remove cylinder and see if
pump builds and holds pressure
against coupler at hose ends. If it
does, problem is in the cylinder.
If it doesn't, observe valve drain
line with pump running. If oil is
running out of drain line, problem
is in valve. If not the problem,
disassemble pump and check for
worn or damaged parts.
