3.5 Safety devices

● Operating pressure switch (see fig. 3/5): determines STOP and START pressures
● Oil level control (if provided).
1) Oil level is checked every 5 seconds during compressor standard operating mode. If the feeler detects a low oil
level for 12 times in a row, the compressor is stopped and the warning light (fig. 9 - ref. 2) turns on (steady
light).
What to do: power off and check the oil level, top up if necessary. Allow some minutes and then restart the
compressor. Should the machine stop once again, call an authorized service center.
2) If the light (fig. 9 - ref. 2) flashes after starting up the compressor or during compressor standard operation, the
following might have happened:
feeler short-circuited or contact open. Call an authorized service center in any case, as the feeler needs to be replaced.
Should the above happen, the compressor can work for 3 hours more. Then it should be powered off and on again
to continue working until the feeler is replaced.
● Oil level light (fig. 9).
ALWAYS CHECK OIL LEVEL BEFORE RESTARTING THE COMPRESSOR.
Close the air cock between compressor and tank (if present).
