FUEL SYSTEM

PREVENTIVE MAINTENANCE

Fuel is an important factor to ensure the good
operation of the engine for a long time and without
failures.

The fuel must be clean, free of water and
impurities.

If the fuel used in the engine has to be stored, see
FUEL STORAGE.

During the engine operation, be aware to the fuel
indicator.

Fill the tank before the volume reaches the
minimum, because sedimented impurities in the
bottom of the tank can be suctioned, damaging
the filter.

Filling

1.

Clean filling inlet duct cover whenever
necessary.

2.

Every end of working day, fill the tank in order
to avoid the condensation of the air humidity.

Warning:

After tank filling, keep it very well
closed. Never improvise. If the
cap presents any problem,
replace it to a genuine spare
part.

Warning:

Bleed the system every time
the engine stops due of a fuel
lack.

Warning:

Do not smoke or get close any
type of exposed blame or
sparks while filling the tank,
because diesel fuel is very
inflammable.
