Maintenance
DAILY OR BEFORE EACH OPERATION
·· Check lubrication levels. Fill as needed.
·· Drain receiver tank condensation.
·· Check for unusual noise or vibration.
·· Ensure area around compressor is free from rags, tools, debris, and
flammable or explosive materials.
WEEKLY
·· Check safety/relief valves by pulling rings. Replace safety/relief valves
that do not operate freely.
·· Inspect air filter element. Clean if necessary.
1. Before maintenance operation, stop the
air compressor, cut off power supply and
discharge all air in the air tank.
2. Clean crank case and renew lubricating oil
after the first 10 working hours.
3. Check the oil level daily, and replenish if
necessary (Fig.3).
4. Clean crank case and renew the oil, clean air
filter every three months or 120 hours.
5. Open the drain cock under the tank to exhaust
the condensate daily.
6. Check the safety valve and pressure gauge
every 6 months and make sure they are in
correct condition.
7. Make sure there is no rust on the air tank and
the air tank is not damaged. FIG. 3
Caution
MONTHLY
·· Inspect for air leaks. Squirt soapy water around joints during
compressor operation and watch for bubbles. Tighten fittings if
necessary.
·· Clean exterior.
3 MONTHS OR 120 HOURS
·· Change petroleum lubricant in pump while crankcase is warm.
12 MONTHS OR 1000 HOURS
·· Replace air filter element.
1. Put the cover off first and put the
breath pipe on the oil-hole and set the
air filter before the compressor run
(Fig.4).
2. Never unscrew any connecting part
when the tank is in pressure condition.
3. Never disassemble any electrical part
before disconnecting the plug.
4. Never adjust the safety valve carelessly.
5. Never use the compressor in place
where voltage is too low or too high.
6. Never use electric wire more than
5m long with less than the section of
1.5mm2, 16A.
7. Never disconnect the plug to stop
compressor, set the switch knob in
position off instead.
8. If the release valve doesn’t work
as motor stopped, find the cause
immediately so as not to damage
motor.

should be kept in red circle of the oil
leveler.
10. Before restarting the motor by
pushing the reset button, check the air
compressor carefully, find the causes
