SYMPTOM

PROBABLE CAUSE

4. Tools seals are blown.

Pump will not build

pressure.

2. Defective relief or regulator valve.

3. Low oil or clogged filter.

4. Internal leak in oil line from external relief

valve to pump body.

5. Defect Solenoid or regulating valve.

Motor sluggish and

2. Clogged filter.

slow to build pressure.

Pump heats up.

1. Improper use.

2. Remote control is left in "on" position

when pump is not actively in use.

Pump cannot reach

10,000 psi, only 9,000psi

Pressure can't reach

1. Check piping

Uncontrolled pressure

1. Check coupling Part#10190

2. Check pumps Part# 10168-10169-10170 2A. Remove the pump from the tank

REQUIRED ACTION

Check air pressure or voltage.

Replace valve. SHOP JOB.

Fill reservoir and clean filter.

Open reservoir, inspect oil line while trying to build

pressure- if leaking tighten fittings or replace.

See "Cylinder will not build pressure-#2 above"

See #1 in preceding block

Clean or replace filter

Operator is continuing to hold down on the advance

stroke after the cylinder has reached end of stroke- this

causes a lot of oil to go through a very small hole in relief-

valve- causing heat build-up. Have operator release

advance stroke after disengagement levers spring

forward.

Turn pump off whenever not actually being used. DO

NOT leave pump running when tool is not in use.
