Never test the ignition system with
ignition wire terminal removed from
spark plug or with unseated spark plug,
since uncontained sparking may cause
a fire.
:DUQLQJ
To reduce the risk of fire and burn injury,
use only spark plugs authorized by
STIHL. Always press spark plug boot
snugly onto spark plug terminal of the
proper size. (Note: If terminal has
detachable SAE adapter nut, it must be
attached.) A loose connection between
spark plug terminal and ignition wire
connector in the boot may create arcing
that could ignite combustible fumes and
cause a fire. Keep spark plug clean, and
make sure ignition lead is in good
condition.

Do not operate your trimmer if the
muffler is damaged, missing or modified.
An improperly maintained muffler will
increase the risk of fire and hearing loss.
Never touch a hot muffler or burn will
result. If your muffler was equipped with
a spark-arresting screen to reduce the
risk of fire (e.g. in the USA, Canada and
Australia), never operate your trimmer
if the screen is missing or damaged.
Do not modify or remove any part of the
muffler or spark arresting screen.
Remember that the risk of forest fires is
greater in hot or dry weather.
Tighten all nuts, bolts and screws,
except the carburetor adjustment
screws, after each use.
Additionally, the daily maintenance
schedule for your trimmer set forth
in your STIHL Owner's Manual should
be strictly followed.
For any maintenance please refer to the
maintenance chart DQG WR WKH ZDUUDQW\
VWDWHPHQW near the end of this manual.
Store trimmer in a dry, high or locked
location out of reach of children.
Before storing for longer than a few
days, always empty the fuel tank.
