Maintenance and Care
ENGLISH 10
4.6 Air Filter Maintenance
The air filter separates and retains dirt before the air
reaches the combustion chamber. This reduces engine
wear.
Regular maintenance increases engine life.
Clogged air filters cause performance loss and
increased fuel consumption. This leads to a higher
toxin level in the exhaust gas and also makes starting
more difficult.
When the machine is used all day, the air filter should
be cleaned daily. In severe dust conditions clean more
often in between.
For a simple cleaning procedure we recommend
tapping the air filter.
Never use a high pressure air cleaner nor wet or
moist cleaning. Do not use solvent or oil bath
cleaners!
If engine rpm's tend to drop although the carburettor
adjustments are perfectly set, the air filter cartridge is
clogged and must be replaced by a new one
(Type 444: Order-Nr. 20 48 282)
(Type 450: Order-Nr. 20 48 280).
Never do realignments on the factory carburettor
settings in order to balance a clogged air filter system.
This procedure would cause engine damages due
overload of the engine.
Warranty claims cannot be accepted for damaged
engine parts caused by improper care and
maintenance
For removal of the air filter, remove filter cover.
Remove filter cover screw (Fig. 1 Pos. 8).
