Maintenance and Service
Diesel engine
304 / 476
The filter cartridges may only be removed when the engine is shut down. The safest,
quickest and cleanest way of maintaining the filter cartridges is exchanging them for
new cartridges.
The main elements may, as described below, be cleaned. As slight damage is often
very difficult to detect or cannot be detected at all, we recommend, in order to pro-
tect the engine, always use new filter cartridges. We do not assume any warranty for
cleaned elements and the consequences caused by them.

When replacing the filter cartridge, the old cartridge must be disposed of in accor-
dance with the local environmental regulations:
– Open filter housing.
– Carefully remove the main cartridge from the inner pipe by rotating it gently and
make sure that it cannot be damaged.

– Thoroughly clean the inside of the housing with the moist cloth - especially the
sealing surface for the filter cartridge. Be very careful so that no dirt get into the
pure air side of the filter.
– Never wash or brush out the main element. When blowing out, take the great care
that no dust reaches the internal side of the main element.
– Blow out using a compressed air gun. This gun must be fitted with the pipe, having
an angle of 90° at the lower end (see illustration).
