–
Never attempt to modify the controls or safety
devices.
–
Keep the handles dry and clean – free from oil
and dirt – this is important for safe control of
the machine
–
Adjust the harness and handle(s) to suit your
height and reach Observe the chapter "Fitting
the Harness" – "Balancing the machine"
To reduce the risk of personal injury, do not
operate your power tool if it is damaged or not
properly assembled!
To prepare for emergencies when using a har‐
ness: Practice setting down the machine quickly.
To avoid damage, do not throw the unit to the
ground when practicing.
2.5 Starting the engine
Start the engine at least 3 meters from the fuel‐
ing spot, outdoors only.
Place the unit on firm ground in an open area.
Make sure you have good balance and secure
footing. Hold the unit securely. The cutting
attachment must be clear of the ground and all
other obstructions because it may begin to run
when the engine starts.
This is a one-person machine – ensure that there
is no-one within 15 meters of the machine, not
even when starting the power tool! Risk of injury
due to ejected objects!
Avoid contact with the cutting attach‐
ment – risk of injury!
Do not drop-start the power tool –
start the engine as described in the
User Manual. The cutting attachment
runs on for a short while after releas‐
ing the throttle trigger – coasting
effect!
Check engine idling: The cutting attachment
must remain at a standstill when the engine idles
– throttle trigger released.
Keep easily combustible materials (e. g., wood
chips, bark, dry grass, fuel) away from hot
exhaust gases and hot muffler surfaces – risk of
fire!
2.6 Holding and guiding the
machine
Always hold the unit firmly with both hands on
the handles.
Make sure you always have a firm and secure
footing.

Right hand on control handle, left hand on grip
on handlebar.
2.7 While working
Make sure you always have a firm and secure
footing.
In the event of impending danger or in an emer‐
gency, switch off the engine immediately by
pressing the stop switch.
15m (50ft)
There is a risk of accident from ejected objects
within a wide area around the working space, so
you must ensure that there is no-one within a
15 m radius of the machine. This distance must
also be maintained in relation to objects (vehi‐
cles, window panes) – risk of property damage!
Even at distances beyond 15 m, the danger can‐
not be ruled out.
Check that the engine is properly idling so that
the cutting tool will not continue rotating after you
release the throttle trigger.
Check and correct the idle speed setting at regu‐
lar intervals. If the cutting attachment still rotates
at idle speed, have your dealer make proper
adjustments or repairs. STIHL recommends you
have this work done by a STIHL servicing dealer.
Take special care in slippery conditions – damp,
snow, ice, on slopes or uneven ground.
Watch out for obstacles: tree stumps, roots – risk
of tripping or stumbling!
Only work while standing on the ground, never
on a ladder or mobile elevated work platform.
Be particularly alert and cautious when wearing
hearing protection because your ability to hear
warnings (shouts, alarms, etc.) is restricted.
Take breaks when you start getting tired or feel‐
ing fatigue – risk of accidents!
