1. Dismantling the air filter:
■
Loosen the air filter screw (15/1) until the
air filter housing cover (15/2) is loose.

Checking/replacing fuel filter (16)

The felt-like fuel filter is located in the fuel tank
and is plugged onto the vacuum head. If the fuel
filter becomes hard, dirty or clogged, less petrol
flows to the engine. In this case, the fuel filter
must be replaced.
It is recommended that an authorised service
workshop carries out this work.

Servicing the spark plug (17)

1. Removing the spark plug:
■
Remove the spark plug connector (17/1).
■
Unscrew the spark plug (17/3) using a
spark plug spanner (17/2).
2. Assessing the condition of the spark plug:
■
If the spark plug is reddish-brown: The
engine is working correctly and the spark
plug is in order. If necessary: Carefully
brush the spark plug clean using a fine
wire brush (17/4).

■
If the spark plug is sooty, oily, encrusted,
melted or bridged: The spark plug is de-
fective. Replace the spark plug with a
new spark plug. Use the specified spark
plug type (see chapter 13 "Technical da-
ta", page 39).
■
If, after a short period of operation, the
spark plug is defective again, the engine
and the carburettor settings must be
checked by an authorised service work-
shop.
3. Check the electrode spacing:
■
Use a feeler gauge (17/5) to check that
the electrode gap (17/6) is 0.6 – 0.7 mm.
If not, carefully tap the electrodes closer
together or carefully bend them apart.
4. If the specified interval is reached or the
spark plug is defective:
■
Replace the spark plug with a new spark
plug. Use the specified spark plug type
(see chapter 13 "Technical data",
page 39).
5. Installing the spark plug:
■
Ensure the spark plug seal ring (17/7) is
on the spark plug.
■
Screw in the spark plug again by hand
and tighten using the spark plug spanner
(torque 12 – 15 Nm).
■
Push on the spark plug connector again
firmly.
