BEFORE OPERATION
f Place the compressor in a clean, dry and well-ven-
tilated environment.
f Keep the voltage variation between ±5% of the
rated value.
f Keep the oil levels in the red circle leveler.
f It is recommended to use SAE30 compressor oil
f Open the outlet valve, set the knob of the pres-
sure switch in position "ON" (Fig.2) and let the
compressor run for 10 minutes with no load, in or-

der to ensure the lubrication of the moving parts
before regular service.
OPERATION AND ADJUSTMENT
f The compressor is controlled by the pressure
switch, when it is working under normal condi-
tions. It stops automatically as pressure increases
to the max and restarts as pressure decreases to
the min. The rated pressure has been adjusted
when produced. As soon as the motor is switched
off, the compressed air in the discharge pipe
should be released through the release valve un-
der the switch. This condition is necessary in or-
der to restart, or else the motor will be damaged.
The rated pressure can be adjusted by turning the
bolt of the switch.
f The output pressure of compressed air can be ad-
justed by the regulating valve. Pull up the knob
of regulation valve and turn it clockwise or coun-
terclockwise, in order to increase or decrease the
pressure.
f The compressor, while operating, can be stopped
only by setting the pressure switch in position "OFF".
CAUTIONS
f Remove the cover and put on the breath pipe and
the air filter before the compressor runs.
f Never unscrew any connecting part when the
tank is in pressure condition.
f Never disassemble any electrical part before dis-
connecting the plug.
f Never adjust the safety valve incautiously.
f Never use the compressor in a location where
voltage is too low or too high.
f Never disconnect the plug to stop the compres-
sor, always set the switch knob in position "OFF"
instead.
f If the release valve doesn't operate when the mo-
tor stops, find the cause immediately so as not to
damage the motor.
f The lubricating oil must be clean; oil levels should
be kept in the score of oil ruler.
f Pull out the plug in order to turn off the power
supply and then open the outlet valve.
f MANUAL THERMAL OVERLOAD SWITCH: The
electric motor has a manual thermal overload
protector. If the motor overheats for any reason,
the thermal overload protector will turn off the
motor. Turn pressure switch in position "OFF" and
wait for the unit to cool, before pushing the reset
button and restart the compressor
f Before inserting the plug into the socket, you
must replace the transport plug with the oil plug!
MAINTENANCE
Maintain the crankcase clean and replace the lubri-
f
cating oil after the first 10 working hours.
Clean the oil levels every 20 working hours and re-
f
place if necessary.
Open the drain cock under the tank to exhaust con-
f
densate every 60 working hours.
Maintain the crankcase clean, renew the oil, clean
f
the air filter and check the safety valve and the pres-
sure gauge every 120 working hours.
