CHECK THE NON-RETURN VALVE (EVERY 6 MONTHS)
If the tank pressure decreases for no apparent reason, it is possible that the
non-return valve is leaking. To check,
1. Make sure that the tank is not
under pressure and the
compressor is switched OFF.
2. Examine the non-return valve,
and replace the gasket and valve
if necessary.
CHANGING THE OIL
1. Switch off the compressor and disconnect from the mains supply.
2. Release any air pressure in the hoses.
3. Hold a collection vessel under the
oil drain plug.
4. Unscrew the oil drain plug from
the compressor pump.
• Collect the oil in the vessel.
• If the oil does not drain out
completely, we recommend
tilting the compressor slightly.
5. When the oil has drained out, refit
the oil drain plug.
6. Dispose of the old oil in an enviromentally responsible way.
