MAINTENANCE
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.
FUEL ADDITION
Add diesel fuel (the grade may vary according to season and locations).
Removing Water from the Fuel Tank
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.
Cleaning Inside the Fuel Tank
If necessary, drain the fuel inside the fuel tank completely. Using a spray washer (Figure 63) wash out any deposits or debris that have accumulated inside the fuel tank.
Figure 63. Fuel Tank Cleaning
FUEL TANK INSPECTION
In addition to cleaning the fuel tank, the following components should be inspected for wear:
Rubber Suspension — look for signs of wear or deformity due to contact with oil. Replace the rubber suspension if necessary.
Fuel Hoses — inspect nylon and rubber hoses for signs of wear, deterioration and hardening.
Fuel Tank Lining — inspect the fuel tank lining for signs of excessive amounts of oil or other foreign matter.
Replacing Fuel Filter
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
AIR REMOVAL
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 Komatsu Engine Manual for details.
To restart after running out of fuel, turn the switch to the “ON” position for 1530 seconds. Try again, if needed.
