Changing the fuel pre-filter
Only proceed with the engine stopped.
q Should the filter be fitted with a
sensor to detect the presence of
water (3), remove the whole
sensor from its seat.
q Remove the pre-filter by
unscrewing it.
q Check that the new filter has
performance levels that satisfy the
needs of the engine (e.g. by
comparing them with the old
one).
q Damp the new filter seal with
diesel or engine oil.
q Hand screw the new filter into
place until the seal gasket touches
the support, then lock by a
further 3/4 of a turn.
q Place the water presence sensor
in its seat, taking care to couple
the threads correctly.
q Loosen the bleeder screw (2) on the pre-filter support and activate
the hand pump (1) until the supply circuit is full. Ensure that any fuel
coming out is not dispersed into the environment.
q Lock the bleeder screw tightly.
q Start the engine and run it at idle for a few minutes to eliminate any
residual air.
q Check the efficiency of the earthing connection of the filter support
(4).
Note: Should it be necessary to accelerate the bleeding phase, the
hand pump can be used during start-up.
Check exhaust pipe/s for damage
Visually check that the exhaust system is not blocked or damaged.
q Make sure that there is no risk of dangerous fumes within the
machine. Contact the Manufacturer if necessary.
Impurity drainage or suction from fuel tank
Proceed taking into consideration the constraints of the tank’s
placement and structure.
The engines working in harsh environments and conditions and/or to
be refuelled from cans or barrels require even more accurate tank
cleaning.
Change auxiliary member belt
Please refer to the information provided for checking the belt tension.
Air filter replacement
Refer to the instructions provided for air filter cleaning.
Change coolant
Only proceed with the engine stopped and at a low temperature, so
as to avoid the risk of burning.
q Provide suitable containers to ensure that no coolant is dispersed
into the environment.
