If the engine is operating in very dusty or dry grass 
conditions, a clogged air cleaner will result. This can lead to 
a loss of power, excessive carbon buildup in the combustion 
chamber and high fuel consumption. Change air cleaner 
more frequently if these conditions exists.

Add diesel fuel (the grade may vary according to season 
and locations).

After prolonged use, water and other impurities accumulate 
in the bottom of the tank. Occasionally inspect the fuel 
tank for water contamination and drain the contents if 
required.

During cold weather, the more empty volume inside the 
tank, the easier it is for water to condense. This can be 
reduced by keeping the tank full with diesel fuel.

If necessary, drain the fuel inside the fuel tank completely. 
Using a spray washer (Figure 53) wash out any deposits 
or debris that have accumulated inside the fuel tank.

In addition to cleaning the fuel tank, the following 
components should be inspected for wear:

 



— look for signs of wear or 

deformity due to contact with oil. Replace the rubber 
suspension if necessary.

 



— inspect nylon and rubber hoses for signs 

of wear, deterioration and hardening.

 



— inspect the fuel tank lining for signs 

of excessive amounts of oil or other foreign matter.

Replace the fuel fi lter cartridge with new one every 500 

 



hours or so.

Loosen the drain plug at the lower top of the fuel fi lter. 

 



Drain the fuel in the fuel body together with the mixed 
water. DO NOT spill the fuel during disassembly. 

Vent any air

 



If air enters the fuel injection system of a diesel engine, 
starting becomes impossible. After running out of fuel, 
or after disassembling the fuel system, bleed the system 
according to the following procedure. See the ISUZU 
Engine Manual for details.

To restart after running out of fuel, turn the switch to the 
“ON” position for 15-30 seconds. Try again, if needed.
