4. Turn the unit on and crank it for 20 seconds.
5. Check the suction and oil pressure gauges
while cranking. Oil pressure is determined by
subtracting suction pressure from the pressure
on the gauge at the oil pressure port.
6. If at least ten pounds of oil pressure is not
developed in the first thirty seconds, allow the
starter to cool for a few minutes and crank
again for 20 seconds. If oil pressure still does
not develop, check the compressor oil level. If
the level is above the oil pickup screen, the oil
pump or relief valve will need to be
rechecked.
7. As soon as oil pressure is developed,
reconnect the fuel solenoid.
CAUTION: Do not crank the unit for
more than 20 seconds or damage to the
starter motor may occur.
