Troubleshooting

Problem
Cause Cause Cause Solution Solution Solution
Check dipstick to ensure that hydraulic
reservoir is properly filled.
Make sure the hydraulic pump inlet fitting is
fully tight, to ensure no air is leaking into the
hydraulic pump inlet. Pump is not primed or lost its
prime.
To prime pump, run unit at lowest pressure
setting and slowly increase pressure. In
some cases it may be necessary to remove
cover shroud, belt guard, and drive belt to
allow for manual (counterclockwise) rotation
of hydraulic pump. Turn fan pulley by hand.
Verify oil flow by removing oil filter to see
flow into filter manifold. Reinstall oil filter. Do
NOT operate unit without a properly installed
oil filter.
Screeching noise is
characteristic of cavitation
and is normal at initial startup for
a maximum of 30 seconds. If noise continues longer than 30 seconds,
turn off main power disconnect to shut off
the motor. Check that the hydraulic pump
inlet fittings are tight and that the pump has
not lost its prime.
Hydraulic fluid is too hot. Ensure that the reservoir is properly
serviced. Improve ventilation to allow more
efficient heat dissipation.
Hydraulic pump does not
develop pressure. Low
or zero pressure with
screeching noise.
Drive belt loose or broken. Check drive belt condition. Replace if
broken.
Loose connections Check connections in electrical enclosure.
Check for 200–240 VAC at input of motor
contactor.
Circuit breaker tripped Reset breaker inside the electrical control
box (R).
Electric motor will not start or
stops during operation
Over temperature switch in the
motor is tripped. Wait for the motor to cool, then restart the
motor.
Air compressor surging or
output low Restriction in air compressor
outlet path Verify that the air hoses, fittings, and cooling
tube on the machine are free of debris. Also,
verify that the air relief valve (part 17H606)
and muffler (part 120206) are clean and free
of debris.
