4 Safety Precautions
￭ The machine can be damaged if you open the throttle
while the cutting attachment is blocked by an object.
► Shut off the engine. Then remove the object causing the
blockage.
￭ If the behavior of the trimmer changes during operation or
feels unusual, it may no longer be in a safe condition. This
can result in serious injuries and damage to property.
► Stop work and contact your STIHL dealer for
assistance.
￭ Trimmer vibrations may occur during operation.
► Take regular breaks.
► If signs of circulation problems occur: Seek medical
advice.
￭ If the cutting attachment makes contact with a foreign
object during operation, the object or parts of it may be
thrown at high speed. This may result in personal injuries
and damage to property.
► Clear away all foreign objects from the work area.
￭ If the rotating metal cutting attachment makes contact with
a hard object, sparks may occur and the cutting
attachment may be damaged. Sparks may cause a fire in
an easily combustible location. This can result in serious
or fatal injuries and damage to property.
► Do not work in an easily combustible location.
► Make sure the metal cutting attachment is in a safe
condition.
￭ Note that the cutting attachment continues to rotate for a
short period after you release the trigger. This can result
in serious injuries.
► Wait until the cutting attachment comes to a complete
stop.
￭ In an emergency, the user may panic and not put the
carrying system down. This can result in serious injuries.
► Practice removing and putting down the carrying
system.
4.9 Reactive Forces
Kickout can be caused for the following reasons:
– The shaded area or the black area of the rotating metal
cutting attachment comes into contact with a solid object
and is suddenly braked.
– The rotating metal cutting attachment gets pinched in the
cut.
The risk of kickout is greatest in the black area.
► Wear gloves.
