5.6.3 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.
5.7 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/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.
If pump does not start when switch (b) is activated,
check fuse in CCM fuse box
