and take up slack if necessary, provided that
these can be reached during maintenance work.
Do not tighten the cylinder head bolts.
The engine must be switched off and
cooled down before cleaning !

Insert exhaust screen with hook q into hole, then
pull outwards again so that the hook is retained.

The maintenance intervals for the fuel filter are
dependent upon the purity of the diesel oil being
used and, if necessary, may have to be reduced to
250 hours.
When working on the fuel system, do not
expose it to naked flames; do not smoke.
WARNING
Keep the entire area clean so that no dirt
reaches the fuel. Fuel particles may
damage the injection system.
