Oil change: In principle, an oil change is not mandatory if the system is correctly manufactured
and operated.
However, based on decades of experience we recommend that the following oil change/service
work is carried out:
-
First oil change during the first maintenance system.
- Then after every 10,000 – 12,000 operating hours, though no more than
3 years, cleaning oil and suction filter at the same time.
Annual checks: Oil level, tightness, running noise, pressures, temperatures, function of auxiliary
devices such as a oil sump heater, pressure switch.
