Maintenance
In order to guarantee optimum operational reliability and service life of the compressor,
we recommend
carrying out servicing and inspection work at regular intervals:
Oil change:
-
not mandatory for factory-produced series systems.
-
for field installations or when operating near the application limit: for the first time after 100
to 200 operating hours, then approx. every 3 years or 10,000 - 12,000 operating hours.
Dispose of used oil according to the regulations; observe national regulations.
Annual checks:
Oil level, leak tightness, running noises, pressures, temperatures, function of
auxiliary devices such as oil sump heater, pressure switch.
WARNING! Before starting any work on the compressor:
Switch off the compressor and secure it to prevent a restart.
Relieve compressor of system pressure.
Prevent air from infiltrating the system!
After maintenance has been performed:
Connect safety switch.
Evacuate compressor.
