Oil change
Change:
–
After 9000 operating hours, however, at the latest after two years.
–
For other types of oil the appropriate oil change intervals must be complied
with.
Building up a pressure cushion
To enable a quick draining of the oil from the compressed air/oil tank and to
overcome a difference in height a small pressure cushion can be built up (ap-
prox. 22 psig system pressure). This pressure cushion forces the oil through
the drain hose into a suitable collecting basin.
Caution: Risk of injury!
Take extreme care when checking the servicing cover for leaks and always
observe all safety measures!
NOTICE!
The service life of the oil, the oil filter and oil separators is reduced under the
following conditions:
–
When the compressor is operated at extreme ambient temperatures.
–
When the intake air is extremely soiled.
