Changing intervals for oil filter cartridge
The operating conditions (e.g. coolant temperatures),
the operating modes and the quality of the intake air
(e.g. content of dust, content of gaseous foreign matter
such as SO , solvent vapours, etc.) have a strong

influence on the service life of the filters (air filters, oil
filters, fine separators).
Where such conditions exist the filter element may
require changing more frequently.
