Lubricating The Gearbox; Replacing The Starter Rope And Rewind Spring - Stihl HS 81 Instruction Manual

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.

gear housing.
: Screw the tube of grease (2) into the
filler hole.

down firmly.
