Bleeding of fuel system
If the fuel runs out or any fuel hose has worked loose al-
lowing air to enter, the fuel system must be bled. Open
the bleed screw (1) on the fuel injection pump, and turn
the spanner so that the electric fuel pump then feeds fuel.
Tighten the bleed screw as soon as there are no air bubbles
visible in the fuel owing out.
Fuel tank
Drain and clean the fuel tank once a year to prevent the in-
gress of any condensation water in the fuel injection pump.
Tilt the machine to the left and remove the magnet plug. This
magnet drain plug is located to the left, behind the rear bogie
axle.
AIR FILTER
The air lter prevents the ingress of dust and other impuri-
ties in the engine. The engine wear is highly dependent on
the cleanliness of the intake air. It is therefore extremely
important to inspect the lter at regular intervals and to look
after it in the correct way.
Do not run the diesel engine under any circumstance without
the air lter or with a damaged lter. Check that the hose
between the air lter and the engine intake is tight.
The air lter is located at the top of the engine. It is of the
dry lter type with a paper lter element.
Cleaning and changing of the air lter
Clean the lter element after every 150 hours of service, e.g.,
with compressed air, see the illustration.
Change the lter element after every 400 hours of service.
• Open the engine hood.
• Detach the air lter from its support.
• Unscrew the wing nut at the end of the air lter and
take out the lter element.
Clean it or change it.
• Replace in the reverse order.
If the engine fails to start, loosen the pressure lines at one
distributor at a time and run with the starter motor until fuel
free from air is sprayed out. Then tighten the pressure line
bolted joints.
