Figure 7-2 Oil Filter Replacement
7.5 Air Filter Replacement
During maintenance work, take care that no dirt enters the clean air side of the air filter.
In accordance with the provisions, the exchange cartridge of the intake air filter shall be
replaced after every
1000 hours of running time. If intake air is strongly polluted, an earlier
exchange or cleaning of the cartridge is required whenever the optical or electronically
maintenance indicator shows it.
Only perform checks and carry out work on the screw compressor when
the unit is out of operation and depressurized!
Never operate the screw compressor unit without the air filter (even a
short operating time without this filter can result in considerable damage
to the machine).
Maintenance Operations:
1. Switch off the unit, disconnect the power, and lock and tag to prevent accidental starting.
2. Allow one minute after stopping for the system to settle and the pressure to be relieved.
3. Loosen the latch that secures the element and remove the cover.
