WARNING
Arcing may occur if the adapter nut (1) is loose
or missing. Working in an easily combustible or
explosive atmosphere may cause a fire or an
explosion. This can result result in serious inju‐
ries or damage to property.
► Use resistor type spark plugs with a properly
tightened adapter nut.
13.3 Installing the spark plug
► Screw home the spark plug, fit the boot and
press it down firmly.
14 Engine Running Behavior
If engine running behavior is unsatisfactory even
though the air filter is clean and the carburetor is
properly adjusted, the cause may be the muffler.
Have the muffler checked for contamination (car‐
bonization) by your servicing dealer.
STIHL recommends that you have servicing and
repair work carried out exclusively by an author‐
ized STIHL servicing dealer.
15 Storing the Machine
For periods of about 3 months or longer
► Drain and clean the fuel tank in a well ventila‐
ted area.
► Dispose of fuel properly in accordance with
local environmental requirements.
► Run the engine until the carburetor is dry – this
helps prevent the carburetor diaphragms stick‐
ing together.
► Remove, clean and inspect the cutting attach‐
ment. Coat metal cutting attachments with cor‐
rosion inhibitor.
► Thoroughly clean the machine – pay special
attention to the cylinder fins and air filter.
► Store the machine in a dry and secure location
– out of the reach of children and other unau‐
thorized persons.
16 Maintaining the Mowing

put shaft facing up.
16.2 Replacing Nylon Line
Always check the mowing head for signs of wear
before replacing the nylon line.
WARNING
If there are signs of serious wear, replace the
complete mowing head.
The nylon mowing line is referred to as "nylon
line" or "line" in the following.
The mowing head is supplied with illustrated
instructions for replacing the nylon line. Keep the
instructions for the mowing head in a safe place.
