PROBLEM
CAUSE
SOLUTION
Electric motor does not run.
1. No voltage supply.
2. Broken Lead wire or defective
internal wiring.
3. Overheated motor has caused
over current protection to
disengage.
4.
charged.
1. Check battery voltage. (Ensure its charged)
2. Contact your Huck distributor.
3. Wait for motor to cool before restarting.
4. Charge or replace battery.
1. Defective motor controls.
1. Disconnect from power supply & contact your
Huck distributor.
Electric motor stalls, surges,
overheats or will not start
under a load.
1. Low voltage.
1. Refer to the information on page 10 - Pump Op-
Electric overload protector
keeps tripping..
1. Excessive load.
2. Damaged wires or compo-
nents.
1. Allow to cool then restart.
2. Return to service center.
to advance tool(s)
partially or erratically.
1. Fluid level is too low.
2. Quick disconnect couplings
are not completely coupled.
3. Air is in system.
4.
viscous.
5. Bladder capacity is too small
for the size of the tool(s) used.
1. Fill reservoir or bladder according to directions
“Filling The Pump Bladder” under “Set-up In-
structions” section.
2. Check quick-disconnect couplings to tools to
ensure that they are completely coupled. Occa-
sionally couplers have to be replaced because
the ball check does not stay open due to wear.
3. Refer to the section titled “Bleeding the System”
under “Set-up Instructions” section, pg. 10.

5. Use smaller tool(s).
Pump builds pressure but can
not maintain pressure.
1. External leaks.
2. Internal or external leakage
on hydraulic tool.
3. Leaking control valve or check
valve.
1.
Replace leaking pipes or hoses.
2. Remove the tool from the pump. If the pump
builds & maintains full pressure, the tool is de-
fective. Contact your Huck distributor.
3. Contact your Huck distributor.
Pump delivers excess
oil pressure.
1. Faulty pressure gauge.
2. Relief valve not properly set.
1. Calibrate gauge.
2. Contact your Huck distributor.
