7.5 Lubricants / oil
The oil type filled as standard in the factory is marked on the name plate, and this should always be
used, even in the case of maintenance units. Alternative oil types can vary significantly in quality
due to additives or inferior raw materials by the manufacturer. Validation within the compressors entire
operating limits can not be guaranteed, if such alternative oil types are used. It is for this reason,
that we only recommend the use of oil from Bock! Bock assumes no liability for any damage arising
from alternative oil types.
