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.
Annual checks: Oil level, tightness of the compressor, running noise, pressures, temperatures,
function of the auxiliary equipment check.
The valve is maintenance free.
However, constant leakage can occur after blowing off due to abnormal operating conditions. This
leads to reduced performance and increases the compressed gas temperature. In this case check the
valve and replace as necessary.
