SYMPTOM: Machine won't run (CONT.)
POSSIBLE CAUSE POSSIBLE REMEDY
Low oil pressure switch tripped. If the machine stops by low oil pressure
cutout, the switch will have to be manually
reset. Check the crankcase oil level. Restart
the machine by pushing the "Start" push
button. Check the oil level and net oil pressure
(net oil pressure = pressure reading at the oil
pump end bearing housing minus suction
pressure). The oil level should be 1/4 - 3/4
level in the glass. If above 3/4, drain some oil
out. See page 9-8, (Oil Pressure Sensor ).
Cutter motor overload tripped. Check and clear the cutter area and ice
discharge path of all ice. Check voltage and
overload range adjustment against motor
rating. Reset the switch and restart the
machine by the "START" push button. Check
the cutter operation and motor amp draw. If
tripping repeats, but ice is not jammed, check
the cutter bearing for wear, the gear reducer
for resistance, and the motor for defect or
single phasing.
Pump motor overload tripped. Check voltage and overload range adjustment
against motor rating. Reset the switch, set the
"Ice/Clean" switch to the "Clean" position and
restart the machine by the "Start" push button.
Check the pump operation and motor amps. If
tripping repeats, check for a defective
overload, defective motor, or single phasing.
