TROUBLESHOOTING

To help prevent personal injury, any repair work or troubleshooting 
must be done by qualified personnel familiar with this equipment.

WARNING

!           

NOTE:

•  Use the proper gauges and equipment when troubleshooting.
•  It is 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.

•  Plug the outlet ports of the pump when checking for leakage to 

determine if the leak is in the pump or elsewhere in the system.

•  Refer to your pump’s appropriate parts list and the hydraulic and 

electrical schematics when using this troubleshooting guide.

Pump is not delivering oil or 
delivers only enough oil to 
advance ram(s) partially or 
erratically.

  1. Oil level too low.

 
  2. Loose fitting coupler to 

ram.

  3. Air in the system.
  4. Air leak in suction line.

  5. Dirt in pump or filter 

plugged.

  6. Cold oil or oil is too 

heavy (Hydraulic oil is of 
a higher viscosity than 
necessary).

  7. Relief valve or low 

pressure unloading valve 
out of adjustment.

  8. Reservoir capacity is too 

small for the size of the 
ram(s) used.

  9. Defective directional 

valve.

10. Release poppet not 

seating in solenoid 
valve.

11. Sheared drive shaft 

key(s).

12. Motor rotating in wrong 

direction.

13. Vacuum in reservoir.

14. Low pressure pump 

worn.

  1. Fill reservoir to within 1” 

of filler plug with all rams 
retracted.

  2. Check quick-disconnect 

couplings to rams. 
Inspect couplers to 
insure that they are 
completely coupled. 
Occasionally couplers 
have to be replaced 
because the ball check 
does not stay open due 
to wear.

  3. Bleed the system.
  4. Check and tighten the 

suction line.

  5. Pump filter should 

be cleaned and, if 
necessary, pump should 
be dismantled and all 
parts inspected and 
cleaned.

  6. Change to lighter oil.

  7. Readjust as needed.

  8. Use smaller ram(s) or 

larger reservoir.

  9. Inspect all parts carefully 

and replace if necessary.

10. Disassemble, inspect, 

and clean pump to 
remove any dirt.

11. Replace after checking 

pump cavity for broken 
pieces.

12. Refer to electrical 

schematic on motor.

13. Check for plugged vent 

in filler plug.

14. Repair or replace gerotor 

pump.

The force of escaping 
hydraulic fluid could 
cause serious injury. 
Keep hands, face, etc. 
clear of any hydraulic 
leaks.
