4. Tools seals are blown.
Pump will not build
pressure.
1. Air Electric supply is low.
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.
1. Check air pressure or voltage.
2. Replace valve. SHOP JOB.
3. Fill reservoir and clean filter.
4. Open reservoir, inspect oil line while trying to build
pressure- if leaking tighten fittings or replace.
5. See “Cylinder will not build pressure-#2 above”
Motor sluggish and
inefficient “sounds sick”
slow to build pressure.
1. Air or electric supply is low.
2. Clogged filter.
1. See #1 in preceding block
2. Clean or replace filter
1. Improper use.
2. Remote control is left in “on” position
when pump is not actively in use.
1. 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.
2. Turn pump off whenever not actually being used. DO
NOT leave pump running when tool is not in use.
Pump cannot reach
10,000 psi, only 9,000psi
1. Change regulating valve Part# 10006
IA. Remove 3 screws of 4 port block manifold
IB. Remove regulating valve #10006
IC. Replace new regulating valve #10006
ID. Don’t forget metal ring
IE. Check o’rings on block manifold
IF. Replace block manifold
IG. Place 1 drop of loctite on each screw
IH. Tighten screws firmly - double check screws are fully
tightened.
Pressure can’t reach
4,000 psi
1. Change cut off valve(s) Part# 10011
IA. Remove the pump from tank
IB. Change cut-off valves 3,250 psi /70 bar 90% Chance pump
is working
IC. If pump can’t get 10,000 psi change cut-off valve 1,250
psi/350 bar
Pressure not stable (big
variation)
1. Change solenoid Part# 10065 (115v)
Part# 10066 (220v)
IA. Remove top solenoid
IB. Replace new top solenoid
IC. Check o’rings
Pressure not stable
(small variation)
1. Change check valves Part# 20374 Need
special tooling Part#
IA. Remove the pump from tank
IB. Replace check valve
IC. Do not tight too much
IA. Remove the pump from tank or Check piping couplers
IB. Check t-coupler inside the pump
1. Check coupling Part#10190
IA. Remove the pump from the tank
IB. Remove piping
IC. Remove block pump (screws# 20444)
ID. Check attentively coupling
IE. Do not forget to replace keys(part #10184)
2. Check pumps Part# 10168-10169-10170
2A. Remove the pump from the tank
2B. Untighten pump’s screws
2C. Check seals
2D. Replace
2E. Tighten firmly
