Changing oil filter
A changeover-type oil filter, the filter el-
ements of which can be replaced even
during operation, can be fitted on request.

changed at every oil change.
During continuous operation position the
selector lever that both filter halves are in
operation. Observe positions of selector
lever!

termediate position because this
would be liable to interfere with oil
supply. If in doubt stop engine to
change oil filter.
Renewal of filter cartridges

drain plugs À. Use a vessel of sufficient
size to ensure that the oil does not
overflow

when the drain plug is opened.
Risk of burns and scalds.!
D After releasing the clamping bolts Á re-
move filter bowls Â
D Renew filter cartridges Ã. Thoroughly
clean all other parts in cleaning fluid

oil circuit).
D Use new gaskets Ä for reassembly of
filter bowls.

hold the filter bowl Á firmly when tight-
ening the tensioning screw Â.

ous waste and must be disposed of
