SYMPTOM:
Machine won't run (CONT.)
POSSIBLE CAUSE POSSIBLE REMEDY
Low oil pressure switch tripped. If the machine stops by low oil pressure cut-out,
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-
9, Section 9 (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.
