3 Safety Precautions and Working Techniques
3.5
While Working
In the event of impending danger or in an emer‐
gency, switch off the engine immediately by mov‐
ing the slide control / stop switch/button to
0 or STOP.
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.
Avoid contact with the cutting attach‐
ment – risk of injury!
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 regular intervals. If the
attachment still rotates when the engine is idling,
have your dealer check your machine and make
proper adjustments or repairs – see MultiEngine
User Manual.
Never work without deflector suitable
for the respective machine and cut‐
ting tool – risk of injury from ejected
objects!
The gear head becomes hot during
operation. Do not touch the gear
housing – risk of burns!
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!
Check the work site – rocks, metal
objects etc. could get caught up and
ejected – potentially beyond a dis‐
tance of 15 m – risk of injury! Such
objects can also damage the cutting
attachment and other property (e.g.
parked vehicles, windows).
Be particularly careful when working on difficult,
densely grown terrain.

Make sure you always have a firm and secure
footing.
Careful when working on steep slopes – risk of
slipping.
Never operate your power tool with one hand.
Be particularly alert and cautious when wearing
ear protection because your ability to hear warn‐
ings (shouts, alarms, etc.) is impaired.
Take breaks when you start getting tired or feel‐
ing fatigue – risk of accidents!
Work calmly and carefully – in daylight conditions
and only when visibility is good. Proceed with
caution, do not put others in danger.
If your power tool is subjected to unusually high
loads for which it was not designed (e.g. heavy
impact or a fall), always check that it is in good
condition before continuing work – see also
"Before Starting". Make sure the safety devices
are working properly. Never use a power tool
that is no longer safe to operate. In case of
doubt, contact a dealer.
Examine the cutting attachment periodically at
short intervals and as soon as you perceive any
noticeable changes:
– Stop the engine, hold the machine securely,
allow the cutting attachment to come to a stop
– Check condition and secure fitting; watch out
for cracks
– Replace damaged or blunt cutting attachments
immediately, even in the event of minor hair‐
line cracks
Clean grass and plant residue off the cutting
attachment mounting at regular intervals –
remove any build up of material from the cutting
attachment and deflector.
To reduce the risk of injury, shut off the engine
before replacing the cutting attachment.
Do not continue using or attempt to repair dam‐
aged or cracked cutting attachments by means
of welding, straightening or modifying the shape
(unbalanced).
Particles or pieces may come off and hit the
operator or a bystander at a high speed – risk of
most severe injuries!
If a rotating cutting attachment touches a rock or
another hard object, sparks may be generated
which may possibly ignite combustible materials.
Dried-out plants and undergrowth are combusti‐
ble, especially in hot and dry weather. If there is
a risk of fire, do not use cutting attachments in
