Maintenance and care

8.2 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.
Undo the screw (a)
completely (screw
is retained inside
the filter cover) and
remove the filter
cover (6).
The best way to clean the filter is to simply tap out
any dirt or blow it carefully out with a low blast of
air.
Never wash or clean the air filter with heigh
compressed air or by wetting it; never place in
an oil bath or into cleaning solution.
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 (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.
Insert the new or cleaned fabric air filter into the
casing.
Secure the filter cover by turning the screw (a)
clockwise.
8.3 Spark
Plug
The correct spark plug with thermal range 200 is
available under the following brands:
BOSCH WSR6F
CHAMPION RCJ-6Y or similar
The correct electrode gap is 0.5 mm.
Check the plug after every 50 operating
hours and replace if electrodes are worn.
8.4 Shutdown and storage
Clean the power tool after use.
Never use aggressive cleaning solutions or
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.
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.
