6.1 Preparation

6.2 Work to be carried out

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 of the vehicle.
- Then after every 5,000 operating hours, though no more than 3 years, clean the oil strainer
at the same time. If necessary, also empty the oil reservoir at the shaft seal.
D
Annual checks: Oil level, tightness of the compressor, running noise, pressures, temperatures,
GB
function of auxiliary devices such as checking the capacity control.

6.4 Integrated decompression valves

The valves are fundamentally maintenance-free.
However, constant leakage can occur after repeated blowing off due to abnormal operating conditions.
This leads to reduced performance and increases the compressed gas temperature. In this case check
the valves and replace as necessary.
