To reduce the risk of fire and burn
injury, use only spark plugs
authorized by STIHL. Always press
spark plug boot (2) snugly onto
spark plug terminal (1) of the proper
size. (Note: If terminal has
detachable SAE adapter nut, it must
be attached.)
A loose connection between spark
plug boot and ignition wire
connector in the boot may create
arcing that could ignite combustible
fumes and cause a fire.

Lubricating the
Gearbox
1
Use STIHL gear lubricant for hedge
trimmers (see "Special Accessories") to
lubricate the blade drive gear.
After about 25 hours of operation:
:
Remove the screw plug (1) from the
gear housing.
:
Screw the tube of grease (2) into the
filler hole.
:
Roll up the end of the tube to the
next division on the scale. This
forces about 3/4oz (20g) grease into
the gearbox.
:
Refit the screw plug and tighten it
down firmly.

:
Do not pull the rope over the edge of
