5.10 Cleaning the air filter
!
Danger
Do not use gasoline or cleansers with a low
flash-point to clean the air filter element. This
could cause fire or an explosion.
!
Caution
Do not run the engine without an air filter,
since this could cause premature wear of the
engine.
Contaminants or dirt must not enter into the in-
take channel.
Contamination of the air filter depends mainly
on the proportion of dust in the intake air, if
necessary clean several times a day.
Air filters with damaged filter element or seal
ring must be replaced in any case. It is there-
fore recommended to keep at least one air filter
in stock.
The air filter must be changed after several
times cleaning, but at the latest after 1 year.
Each cleaning interval must be marked with a
cross on the cover of the air filter.
Cleaning does not make sense if the air filter is
covered with a sooty deposit. Use a new air fil-
ter.
Incorrectly handled air filters may become in-
effective because of damage (e.g. cracks) and
cause damage to the engine.
