3 Safety Precautions and Working Techniques
If you use a shoulder strap or full harness: Prac‐
tice removing and putting down the machine as
you would in an emergency. To avoid damage,
do not throw the machine to the ground when
practicing.

instruction manual of the power tool attachment
you are using.
3.5 Starting the Engine
Start the engine at least 3 meters from the fuel‐
ing spot, outdoors only.
Place the power tool on firm ground in an open
area. Make sure you have good balance and
secure footing. Hold the power tool securely. The
attachment must be clear of the ground and all
other obstructions because it may begin to run
when the engine starts.
To reduce the risk of injury, avoid contact with
the attachment.
Do not drop start the power tool – start the
engine as described in the instruction manual.
Note that the attachment continues to run for a
short period after you let go of the throttle trigger
– flywheel effect.
Check idle speed setting: The attachment must
be stationary when the engine is idling with the
throttle trigger released.
To reduce the risk of fire, keep hot exhaust
gases and hot muffler away from easily combus‐
tible materials (e.g. wood chips, bark, dry grass,
fuel).

you are using.
3.6 Holding and Controlling the
Power Tool
Always hold the power tool firmly with both
hands on the handles. Make sure you always
have good balance and secure footing.

3.7 During Operation
In the event of impending danger or in an emer‐
gency, switch off the engine immediately by mov‐
ing the slide control / stop switch to STOP or 0.
The correct engine idle speed is important to
ensure that the attachment stops moving when
you let go of the throttle trigger. If the attachment
continues to run when the engine is idling, have
your dealer check your machine and make
proper adjustments or repairs. STIHL recom‐
mends an authorized STIHL servicing dealer.
Check and correct the idle speed setting regu‐
larly.
Be particularly alert and cautious when wearing
hearing protection because your ability to hear
warnings (shouts, alarms, etc.) is restricted.
To reduce the risk of accidents, take a break in
good time to avoid tiredness or exhaustion.
Work calmly and carefully – in daylight conditions
and only when visibility is good. Stay alert so as
not to endanger others.
