0000-GXX-3025-A1
Kickout can be caused for the following reasons:
–
The shaded area or the black area of the rotat‐
ing metal cutting attachment comes into con‐
tact 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 trim‐
mer. This may result in serous or fatal injury to
people.
► Hold the trimmer firmly with both hands.
► Work as described in this user manual.
► Do not use the black area for cutting.
► Use a combination of cutting attachment
and deflector recommended in this instruc‐
tion manual.
► Sharpen the metal cutting attachment cor‐
rectly.
► Work with the engine running at full throttle.
