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.
25.3 Installing the Spark Plug
4903BA008 KN
► Screw home the spark plug, fit the boot and
press it down firmly.
► Fit the shroud.
26 Storing the Machine
For periods of 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 the saw chain and guide bar, clean
them and spray with corrosion inhibiting oil.
► Thoroughly clean the machine – pay special
attention to the cylinder fins and air filter.
► If you use a biological chain and bar lubricant,
e.g. STIHL BioPlus, completely fill the chain oil
tank.
