Important
Dispose of waste oil according to
the currently valid regulations for the
protection of the environment. It is
recommended to take the waste oil
in a leakproof container to a waste
oil collection centre. Do not dispose
of with residual waste or pour onto
the ground and leave to seep away.

Servicing the air filter
A dirty air filter restricts the air flow
to the carburettor. To prevent the
carburettor from malfunctioning, the
air filter should be serviced regularly.
In an extremely dusty environment
more frequent maintenance may be
required.

Operating manual for engine
To ensure that the engine runs
correctly, the gap between the
electrodes on the spark plug
must be set correctly and free of
contaminants.
Figs. 6 and 7
Remove the spark plug
terminal (1) and unscrew the
spark plug (2) with a spark-plug
wrench.
Visually check the spark plug.
Replace the spark plug if it is
clearly worn or the insulator is
damaged.
Clean the spark plug with a wire
brush if it is to be used again.
Measure the gap between the
electrodes with a feeler gauge.
If required, re-adjust the gap by
slightly bending the side elec-
trode. The gap between the
electrodes should be
0.60–0.80 mm (Fig. 7).
Check that the sealing ring on the
spark plug is in good condition,
then screw in the spark plug by
hand to prevent damage to the
thread.
When the spark plug is hand-tight,
tighten with the spark-plug
wrench.
