7.EXHAUST MESH INSERT (See Fig. 5-ithru !0)

WARNING

Exhaust system components will naturally be hot and must not be touched while the engine is running or until it has cooled down after being stopped.

■Unscrew hex nut and remove the exhaust mesh insert. (See Fig. 5-i)

■Remove any deposits in the mesh insert by means of a wire brush.

■Check the exhaust mesh insert for cracks or damage and, if necessary replace with a new one.

■Screw on hexagon nut q by approx. 1 turn. (See Fig. 5-o)

■Tighten the hexagon nut fully.

8.CHANGING FUEL FILTER ELEMENT (See Fig. 5-!1)

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.

6. CHECKING SCREW CONNECTIONS

■Check the tightness of all threaded connections and take up slack if necessary, provided that these can be reached during maintenance work.

Do not tighten the cylinder head bolts.

WARNING

When working on the fuel system, do not expose it to naked flames; do not smoke.

CAUTION

Keep the entire area clean so that no dirt reaches the fuel. Fuel particles may damage the injection system.
