·
The oil level must lie between the
“maximum oil level”
(- 4 - Fig. 17) and
“minimum oil level” (- 5 - Fig. 17).
·
If necessary, top up the oil.
Changing times for lubricants
Operating conditions (e.g., coolant temperatures), the
type of operation and the quality of the intake air (e.g.,
dust content, ratio of gaseous foreign substances such
as SO
2
and solvent vapors) have a strong influence on
the oil change intervals.
In these cases, the operational life of the oil must be
checked by performing an oil analysis (also see Section
10.15).

DANGER
Air/oil under pressure will cause severe
personal injury or death.
·
Shut down the compressor, relieve the
system of all pressure, disconnect,

the compressor package before
removing valves, caps, plugs, fittings,
bolts and filters.

1 Oil filter cartridge
The changing intervals can be found in the
maintenance schedule.
Replace the oil filter cartridge as follows:
·
Switch off the screw compressor unit, secure it
against an accidental restart and ensure that it is
depressurized.
·
Wait at least 5 minutes until the oil has settled, i.e.
until the air has bubbled out.
·
Unscrew the oil filter cartridge (- 1 - Fig. 18) with a
suitable tool
·
Dispose of the oil filter cartridge properly
·
Lightly oil the seal of the new oil filter cartridge
·
Screw on the new oil filter cartridge and tighten by
hand (see the notes on the oil filter cartridge)
·
Let the screw compressor unit run for approx.
2 minutes
·
Check for leaks
·
Check the oil level (see Section 7.5)
·
If necessary, top up the oil.
Changing times for oil filter cartridges
Operating conditions (e.g., coolant temperatures), the
type of operation and the quality of the intake air (e.g.,
dust content, ratio of gaseous foreign substances such
as SO
2
and solvent vapors) have a strong influence on
the filter lifespan (air filter, oil filter, fine separator).
In these cases the intervals between changes may be
shorter
