7.2 Fluid and oil filter change
Warning
The operator must apply all relevant Safety precautions.
Always drain the compressor fluid at all drain points. Used fluid left in the compressor
can contaminate the oil system and can shorten the lifetime of the new fluid.
Never mix lubricants of different brands or types as they may not be compatible and the
fluid mix will have inferior properties. A label, indicating the type of fluid filled ex-factory,
is stuck on the oil tank.
Procedure
Oil system components
1.
Run the compressor until warm. Stop the compressor. Close the air outlet valve and switch off the
voltage. Depressurise the compressor by opening manual d rain valve(s) (if available). Wait a few minutes
and depressurise the oil tank (AR) by unscrewing fluid filler plug (FC) just one turn to permit any pressure
in the system to escape. Also depressurize the air pipe by unscrewing the air vent plug (Fa) with one turn.
2.
Loosen the vent plug of the oil cooler and wait for 5 minutes.
3.
Remove fluid drain plug (DP1). Drain the fluid by opening valve (Vd). Close the valve and fit the plug after
draining.
