Fuel system

CAUTION
Fire hazard
Fuels are highly combustible and harmful to health.
► Avoid fire, open flame, smoking and sparking.
► Do not allow fuel to drip or splash onto electrical systems or hot surfaces.
► Spilled fuel should be wiped up immediately.
Using diesel fuel that contains water can damage the injection system which often results in piston
seizure. This can be partially avoided by filling up while the fuel tank is still warm after switching off the
engine (which prevents condensation). Drain any water from the storage tank regularly. It is also re-
quired to install a water separator upstream of the fuel filter. Flow additives must not be used for winter
operation.
Measures to ensure cleanliness:
■ Protect fuel system from dirt. Clean the vicinity of the fuel system carefully before removing
components.
■ Put a suitable cover on components removed from the fuel system.

Replacing the primary fuel filter

NOTICE
Risk of contamination of drinking water
► Used filter components, seals and residual fuel must be disposed of in accordance with local
regulations.
WARNING
Fire hazard
► Fuel leaked or spilled onto hot surfaces or electrical components can cause a fire. Clean up any
leaked or splilled fuel. Do not smoke while working on the fuel system.
NOTICE
Precaution regarding fuel filter replacement
► Do not fill the fuel filters with fuel before installation. Unfiltered fuel could cause contamination
and accelerated wear of the fuel system parts.
► Be careful not to drop fluid in the vent cavities of the bell housing.
► Do not start the engine if air is not purged from the fuel lines. Always use the fuel priming pump
prior to start the engine after a change of fuel filter.
