3.2 Supplying Fuel
Fires from Oil Ignition
• Be sure to use the correct type of
fuel when refueling. Mistakenly filling
with gasoline, or the like, will result in
ignition.
• Be sure to stop the engine before
refueling. If you spill fuel, wipe such spillage carefully.
• Never place oils or other flammable material close to
the engine as this could result in ignition.
3.2.1 Filling the Fuel Tank
Fill the tank with clean fuel, which has not been
contaminated with water or dust. Fill the tank to
approximately 90% pf its capacity, and take care not
to let the fuel spill over during operation.
3.2.2 Bleeding the Fuel System
Bleed the fuel system according to the following
procedure. When there is air in the fuel system, the fuel
injection pump will not be able to function.
The fuel system includes the fuel tank, water
separator, fuel oil filter, feed pump, fuel injection pump,
high-pressure pipe and fuel injection valve.
If air enters this system, fuel cannot be injected. Bleed
air from the fuel system completely by using the
following procedure:
1 Open all the shut-off valves of the fuel system.
2 Loosen the air bleeding plug of the fuel injection
pump.
3 Loosen the bleeding bolts on the fuel oil filter.
4 Pump the priming knob. When the fuel coming out
of the air-bleeding opening is clear (no more air
bubbles visible) tighten the air bleeding bolts.
