Maintenance and care
9.3 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.
Before opening the air filter housing, close
the choke to prevent dirt entering the
carburettor.
To open the air filter housing press in the black
clamp and open the housing cover downwards.
Remove foam filter.
When the machine is used all day, the air filter
should be cleaned daily. In severe dust conditions
clean more often in between.
For daily cleaning:
Tap the air filter against an object or use an air
gun.
With heavy dust conditions and for normal weekly
check:
Wash a heavily soiled filter in non-flammable
cleaning solvents (warm soapy water).
Wipe the air cleaner housing clean with a dry or
slightly damp cloth. Before inserting the filter, the

housing and the filter must be completely dry
again.
Never insert moist or wet foam filters!
Immediately replace damaged filter parts.
When re-fitting, ensure the filter is positioned and
seated properly.
If the filter material is damaged, replace the
corresponding parts immediately.
Warranty claims cannot be accepted for damaged
engine parts caused by improper care and
maintenance.

Store the device in a dry, safe location inside a
building (garage, basement, ...). There must not be
any open fires or similar nearby. Ensure that the
device cannot be used by unauthorised persons,
especially children.
If not in use for more than four weeks, drain the
fuel tank in a well ventilated location before storing.
Start the engine with an empty fuel tank and drain
the carburettor until the engine stops. Oil residues
from the fuel mixture could otherwise clog the
carburettor jets and make it difficult to start the
device later.

those containing solvents to clean any part of the
engine. Never hose down the engine. For best
results, simply wipe down the entire engine with
a dry or slightly damp cloth.
