Checking the safety
valve
Check:
–
After approx. 3000 operating hours, however, at least once a year.
Check safety valve by opening the screw plug.
NOTICE!
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 soil-
ing of the cooling unit leads to an increased temperature in the oil circuit.
WARNING: Risk of injury!
Prior to any maintenance and servicing work take all necessary safety pre-
cautions described on page 44!
WARNING!
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.
Vacuum out the dirt using
an industrial vacuum
cleaner.
If the cooling unit is exces-
sively soiled (cleaning is no
longer possible with com-
pressed air), have it disas-
sembled and cleaned by
BOGE service.
WARNING: Risk of injury!
Danger of burning due to hot oil!
Take extreme care when checking the safety valve with the compressor run-
ning taking all safety measures into consideration.
Always wear safety gloves!
A hot air-oil mixture escapes when opening!
