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