N Clean dirty spark plug.

"Specifications."
N Use only resistor type spark plugs of
the approved range.

fouling of spark plug:
– too much oil in fuel mix,
– dirty air filter,
– unfavorable running conditions, e.g.
operating at part load.

use only spark plugs authorized by
STIHL. Always press spark plug boot (1)
snugly onto spark plug terminal (2) of the
proper size. (Note: If terminal has

securely 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.
