10.3 Checking/replacing fuel filter (10)

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.
1. Preparing the appliance:
■
To empty the fuel tank: Allow the engine
to run until it stops itself.
■
Place the appliance on a level, horizontal
surface. Cap (10/1) of fuel tank (10/2)
must be facing upwards.
■
Wipe the fuel tank cap, the fuel tank and
the surrounding appliance parts clean so
that no dirt can get into the fuel tank.
2. Checking/replacing the fuel filter:
■
Unscrew cap (10/1) of fuel tank (10/2).
Leave the cap hanging on the fuel tank.
■
Use a wire hook to pull intake head
(10/3) out of the fuel tank.
■
Inspect fuel Filter (10/4). If the felt has
become hard, dirty or clogged: Pull off
the fuel filter and push a new fuel filter
onto the intake head.
3. Push the intake head into the fuel tank again.
4. Mix and pour in the petrol/oil mixture (see
chapter 5.1 "Mixing and pouring in petrol/oil
mixture (06)", page 41).

10.4 Maintaining the spark plug (11)

1. Removing the spark plug:
■
Remove spark plug connector (11/1).
■
Unscrew spark plug (11/3) using spark
plug spanner (11/2).
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 (11/4).
■
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 11 "Technical
data", page 49).
