________PSI The pressure gauge should read zero if the pump is operating correctly.
(should be O)
Begin at the top and close the needle valve slowly clockwise until the engine begins to labor.
________ Checked As the pressure gauge increases to between 500 and 700 PSI and the flow increases to
between 1 and 3 GPM, the high volume check valve should close and the engine RPM will
return to normal.
If the check valve does not close, the engine will bog down and stall and you need to replace
the pump.
Continue to slowly close the needle valve until the pressure increases to between 1500 and
3200 PSI and the flow reads approximately 1 to 2 gallons per minute.
Immediately open the needle valve to relieve the pressure and avoid damage to the pump
and seals.
______ PSI Record your readings on the test data work sheet.
(1500 - 3200 range)
______ GPM If the pressure reading falls below minimum PSI, the pump is defective and should be (1 - 2
range) replaced.
If the pressure reading is within specification, continue trouble shooting.
Move the valve handle to the forward position until the ram fully extends. Hold the valve
open in that position.
Read the gallons per minute from the flow meter and the pressure per square inch from the
pressure gauge. Release the valve and return it to the neutral position.
______ PSI The pressure should read between 1500 and 3200 PSI and the flow reading should be
______ GPM between 1 and (1500 - 3200 range) 2.5 gallons per minute. Record these readings on the
(1 - 2.5 range) work sheet for later reference.
If the pressure is lower than your initial readings, there may be a problem with the control
valve, pressure relief valve or hydraulic cylinder.
It will be necessary to continue to determine which part is at fault.
Remove the test kit from the log splitter and replace the hose. Tighten the connections to
specification.
To test the control valve, pressure relief valve and hydraulic cylinder, place the log splitter in
the vertical position.
Connect the test kit between the control valve and the hydraulic cylinder. The pressure
gauge is to the control valve side and the flow meter is to the hydraulic cylinder end.
