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.
Annual checks: Check the tightness of the compressor, running noise, pressures, temperatures,
function of auxiliary devices.
Only use genuine Bock spare parts!

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.
Release switch lock.
