Cleaning work
General
The following causes of soiling make it neces-
sary to clean the engine:
z
High dust content in the air.
z
Chaff and chopped straw in the area of the
engine.
z
Coolant leakage
z
Lubricating oil leakage
z
Fuel leakage
Because of the different application conditions,
cleaning depends on the degree of soiling.
Cleaning with compressed air
z
Blow dirt off or out. Always blow out the coo-
ler and cooling fins from the exhaust air side
to the fresh air side.
Cleaning with cold cleaner
z
Spray the engine with cold cleaner and lea-
ve it for about 10 minutes to take effect.
z
Spray the engine clean with a high pressure
water jet.
For all cleaning work, make sure that
no parts are damaged (e.g. bent cooler
mesh).Cover electrical/electronic parts
and connections to clean the engine
(e.g. control units, generator, solenoid
valves etc.) Do not aim the water/
steam jet directly at them. Run the en-
gine warm afterwards.
Only carry out cleaning work on the en-
gine when it is not running! Remove
the engine cover and cooling air cover
if available and remount after cleaning.
z
Warm up the engine so that the water resi-
dues evaporate.
Cleaning with a high pressure cleaner
z
Clean the engine with a steam jet (maximum
spray pressure 60 bar, maximum steam
temperature 90 °C, distance at least 1m)
z
Warm up the engine so that the water resi-
dues evaporate.
z
Clean external cooler according to the ma-
nufacturer’s specifications.
