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 con-
nector in the boot may create arcing that
could ignite combustible fumes and
cause a fire.
Unfavorable running conditions,
e.g. operating at part load.
