11 Engine Running Behavior

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.
10.3 Installing the spark plug
► Fit the spark plug by hand and screw it in
► Tighten spark plug with combination wrench
► Press the spark plug boot firmly onto the spark
plug
11 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.

12 Lubricating the Gearbox

Use STIHL gear lubricant for hedge trimmers
(special accessory) to lubricate the blade drive
gear.

After about 50 hours of operation:
► Remove the screw plug (1) from the gearbox.
► Screw the tube of grease (2) into the filler
hole.
► Squeeze up to 5 g grease into the gearbox.
NOTICE
Do not completely fill the gearbox with grease.
► Remove the tube of grease (2).
► Refit the filler plug and tighten it down firmly.

13 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.
► Clean the cutting blades, check condition and
spray with STIHL resin solvent.
► Fit the blade scabbard.
► Thoroughly clean the machine – pay special
attention to the cylinder fins and air filter.
► Store the machine in a dry and safe location
(use the ring integrated in the rear handle) out
of the reach of children and other unauthor‐
ized persons.
