6.4.3.3 Cleaning fuel tanks
To drain sediment and water from the fuel tanks (1),
remove the drain plug (2) of both fuel tanks and
frame.
For a better drainage slightly slope the unit.
Use water to clean the inside of the fuel tanks, use a
high-pressure purifier if necessary. Spurt the
sediment and water to the drain side of the tank.
6.4.4 Cleaning coolers
Keep all coolers clean to maintain the cooling
efficiency.
The fan side surface of the radiator, intercooler,
aftercooler 1 and oil cooler is accessible by opening
the service doors.
The CAC/Charge air cooler, fuel cooler and
aftercooler 2 are located at the rear end of the unit,
under the air filters.
– Remove any dirt from the coolers with a fibre
brush. Never use a wire brush or metal objects.
Then clean by air jet in reverse direction of normal
flow.
– If the dirt is oily, wash the coolers with fuel or a
cleansing agent.
– A spray gun should preferably be used to apply the
solvent to the cooler block. Rinse the block by
means of a water jet after a soaking-in period.
Steam-cleaning may also be applied.
– Close the service doors.
– Do not leave liquids behind.
After cleaning or heavy rains, drain
the spillage-free frame.
Protect the electrical and controlling
equipment, air filters, etc. against
penetration of moisture.
