Stihl FS 40 Notice D'emploi page 24

English
Fit a new spark plug after approx. 100
operating hours or earlier if the
electrodes are badly eroded.
To reduce the risk of fire and burn
injury, use only spark plugs
authorized by STIHL. Always
press spark plug boot (2) snugly
onto 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.
