8.3 Maintenance schedule
Danger
When performing control, adjusting and mainte-
nance work, be careful with hot surfaces of
machine parts.
Checks and maintenance work may only be carried
out when the following points are observed:
•
Press the STOP button on the control panel and
wait until the screw compressor unit has come
to rest and the screw compressor unit is
depressurized
•
The pressure display does no longer indicate
pressures < 0.3 bar/4.4 PSI.
•
Shortly after switching the screw compressor
off, the system can contain a low residual
pressure.
•
The screw compressor unit must therefore be
depressorized prior to any maintenance work by
slowly opening the lock (oil filler cap) with
integral vents
•
The customer-installed main switch is set to "O"
(OFF) and locked off
•
Warning:
Electrical voltage: Only work on the screw
compressor unit when it is disconnected.
Intervals are valid for normal industrial environments
and operating conditions. When in doubt, check the oil
change intervals by carrying out an oil analysis.
If necessary, reduce the oil change intervals and
cleaning intervals in the event of heavy soiling.
For order numbers see the spare parts list.
