cate with approx. 5 strokes from the grease

5.14 Checking, cleaning the dry
air filter
!
Caution
A dirty dry air filter cartridge can be noticed by
excessive exhaust smoke.
A dry air filter cartridge with a damaged filter
element or seal ring must be replaced in any
case. It is therefore recommended to keep at
least one cartridge in stock.
The dry air filter cartridge must be changed af-
ter 500 operating hours, but at the latest after 1
year.
Cleaning does not make sense if the air filter
element is covered with a sooty deposit. Use a
new filter cartridge.
Incorrectly handled filter cartridges may be in-
effective if damaged (e.g. cracks) and cause
damage to the engine.
Always replace the filter cartridge if it is soiled
with wet or oily dirt.
Do not use gasoline or any hot fluids to clean
the filter cartridge.
