TROUBLESHOOTING
DETERMINE THE TYPE OF PROBLEM
Performance problems are classified as “LOSS OF POWER” or “LOSS OF CYCLE
SPEED” (assuming the problem is not due to misapplication) .
1. LOSS OF POWER
NPK M35 Material Processor jaw crushing/cutting forces are determined by the
operating pressure setting and NPK pressure intensifier performance.
2. LOSS OF CYCLE SPEED
NPK M35 Material Processor cycle speed is determined by oil flow to the unit.
The hydraulic installation circuit for the M35 Material Processor must be set to
provide the correct flow.
DETERMINE THE CAUSE OF THE PROBLEM
Technical problems are caused by either the NPK M35 Material Processor or the
carrier’s hydraulic system (hydraulic installation kit for the M35 Material Processor) .
Checking the hydraulic pressure and flow will determine if the problem is in the M35
Material Processor or the carrier. If the pressure and flow to the Processor are correct,
the problem is in the M35 Material Processor.
LOSS OF POWER
Loss of power can be caused by a low carrier relief valve setting or by a low M35
Material Processor relief valve setting. Verify the correct relief valve settings of the
carrier and the M35 Material Processor. (See “M35 PROCESSOR RELIEF VALVE
AND CARRIER RELIEF VALVE SETTINGS”
on page 99.)
If the relief valve pressures are to specification, proceed to the “INTENSIFIER
CHECKS” troubleshooting chart on page 100 and the “PRESSURE INTENSIFIER
OPERATION”
section on page 102.
