Fire And Explosion Hazard!
Diesel fuel is flammable and explosive under certain
conditions.
Before you operate the engine, check for fuel leaks. Replace
rubberized fuel hoses every two years or every 2000 hours of
engine operation, whichever comes first, even if the engine
has been out of service. Rubberized fuel lines tend to dry out
and become brittle after two years or 2000 hours of engine
operation, whichever comes first.
Failure to comply will result in death or serious injury.
Note that a typical fuel tank is shown. The fuel tank on your
equipment may be different.
1. Clean the area around the fuel cap (1, Figure 36).
2. Remove the fuel cap (1, Figure 36) from the fuel tank (2,
Figure 36).
3. Observe the fuel level sight gauge (3, Figure 36) and stop
fueling when the gauge shows the fuel tank is full. NEVER
overfill the fuel tank.
4. Replace the fuel cap (1, Figure 36) and hand tighten.
Over-tightening the fuel cap will damage it.
Priming the Fuel System
The fuel system needs to be primed under certain conditions:
• Before starting the engine for the first time.
• After running out of fuel and fuel has been added to
the fuel tank.
• After fuel system maintenance such as changing the
fuel filter and draining the fuel filter / water separator,
or replacing a fuel system component.
To prime the fuel system:
1. Turn the key to the ON position for 10 - 15 seconds. This
will allow the electric fuel pump t80o prime the fuel
system.
2. Never use the starter motor to crank the engine in order to
prime the fuel system. This may cause the starter motor to
overheat and damage the coils, pinion and / or ring gear.
