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.
Drain water from the fuel pre-filter
The high risk of refuelling with fuel that is polluted by foreign bodies
and water makes it advisable to carry out this control every time you
refuel.
Proceed with the engine stopped.
Place a container under the filter or pre-filter to collect the fluid.
Unscrew the tap plug (1) in the bottom part of the filter; in some
lay-outs the plug includes a sensor to detect the presence of water
in the diesel.
Drain off liquid until only “diesel” can be seen.
Close the plug again, tightening it completely by hand.
Dispose of the drained fluids according to current requirements.
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.
Air filter replacement
Refer to the instructions provided for air filter cleaning.
