Rectify problems which have caused
fouling of spark plug:
N Too much oil in fuel mix.
N Dirty air filter.
N Unfavorable running conditions,
e.g. operating at part load.
Fit a new spark plug after approx. 100
operating hours or earlier if the
electrodes are badly eroded.
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.
N Have the muffler checked for
contamination (carbonization).
STIHL recommends that you have
servicing and repair work carried out
exclusively by an authorized STIHL
servicing dealer.
Warning!
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.
