Maintaining the Engine
Air Filter
When working with the machine for long period
of time, clean the air filter. Dust and pollen will
clog the pores of the foam filter. A damaged air
filter must be replaced immediately, in order not
to shorten the life of the engine.
1. Unscrew the locking screw for the air filter
cover (10) and take of the cover. Behind
the cover you will find the foam filter.
2. When the filter is clogged, wash the filter in mild soapy water.
Attention: Do not use gasoline or solvents for cleaning the filter.
Thoroughly dry the filter before re-attaching. Place the cover on the
motor housing and re-tighten the locking screw.
Spark Plug
1. Wait for the engine to cool down
completely.
2. Remove the spark plug cap from the
spark plug and unscrew the spark plug
with the included spark plug wrench.
3. Use a new one of the same type and
dimensions. Turn the spark plug com-
pletely into the thread by hand. Avoid
tilting the spark plug.
4. Tighten the spark plug with the supplied spark plug wrench.
When using a torque wrench, the tightening torque is 12 – 15 Nm.
Insert the spark plug cap correctly onto the spark plug.
If excessive wear occurs on the
electrode or if the deposit is very hard,
replace the spark plug with the same
type and size. A wrong carburettor,
wrong oil/fuel mixture, bad oil quality,
old petrol mixture or a dirty air filter can
cause deposits on the spark plug, which
