Reactive Forces - Stihl FSA 90 Manual De Instrucciones

English
￭ 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, remove the battery and contact your STIHL
servicing dealer for assistance.
￭ Trimmer vibrations may occur during operation.
► Wear gloves.
► 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.

stop.
￭ In an emergency, the user may panic and not put the
carrying system down. This can result in serious injuries.

system.

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.
WARNING
￭ These situations can abruptly decelerate or stop rotation
of the cutting attachment and cause the cutting
attachment to be thrown to the right or in the direction of
the user (black arrow). The user can lose control of the
trimmer. This can result in serious or fatal injuries.
► Hold the trimmer firmly with both hands.
► Use the working techniques described in this instruction
manual.
► Do not use the black area for cutting.
► Use a combination of cutting attachment, deflector and
carrying system recommended in this instruction
manual.
► Sharpen the metal cutting attachment correctly.
► Cut with the motor running at full speed.
