Maintenance
BOGE Operating instructions for S 40-2...S 341 / SF 40-2...SF 220 series screw compressors
Flushing the oil circuit
Flushing the oil circuit with clean oil becomes necessary:
– When the oil is excessively soiled.
– Prior to changing the oil type.
CAUTION!
Detailed information as to the flushing with BOGE oils you can obtain from
the following service number.
770 -874-1570
Cleaning: – After 1500 operating hours,
however, at the latest after one year.
The service life of the compressed air/oil cooling unit depends on the
degree of soiling (dust, oil vapour) of the suctioned cooling air. Extreme
external soiling of the cooling unit leads to an increased temperature
in the oil circuit.
– Switch off the compressor using the OFF button.
DANGER: Risk of injury!
Switch off the main switch and secure it against unintentional switch-on.
– Remove cladding on the maintenance side.
– Unscrew the maintenance flap on the air guidance box.
– Remove accumulated soiling with a fibre brush.
CAUTION!
Do not use any sharp objects for cleaning!
These could damage the cooling unit!
– Blow down the dirt with compressed air in the opposite direction to the
normal cooling air flow. Clean out the dirt using an industrial vacuum
cleaner (see Fig.).
If the cooling unit is excessively soiled (cleaning is no longer possible with
compressed air), have it disassembled and cleaned by BOGE service.
