Fuel System
Circuit description
The fuel system is based on a fuel feed pump and an in-line mechanical injection pump.
Fuel specifications
Use ASTM Diesel fuel No.2-D for the best genset performance, to prevent genset damage.
Never use kerosene, heavy Diesel fuel or bioDiesel. It is essential to use clean and filtered Diesel oil.
The use of Diesel oil that not complies with the technical specifications may affect warranty
coverage and cause serious damage in the injection system and internal genset components.
Maintenance task. Fuel level inspection
Periodically, it is necessary to check the fuel level to assure the operation of the genset. On
top of that, if fuel pump sucks air when the fuel level is lower than pump suction, it could break.
Whenever possible, keep the fuel tank full. The temperature changes may cause
condensation of the damp air present in the tank and this water accumulates at the bottom. It can
cause an increase of corrosion or an impossibility of starting the genset if this water is aspired by the
fuel pump.
Maintenance task. Fuel tank clean
The fuel impurities could obstruct the suction pump. For this reason, drain out the content of
the fuel tank to remove condensate and any foreign material. Then, wash the tank with fuel and refill
it.
Maintenance task. Water separator filter purge
The fuel system has to have a water separator filter (supplied as accessory) to
avoid the inlet of water in the fuel circuit. According to the maintenance plan it is
necessary to purge the filter to eliminate water periodically. This is the procedure:
1.
Loosen the bottom nut to eliminate water.
2.
Shut it off again.
