Kickback (blade thrust)
Kickback (blade thrust) is a sudden reaction to a caught or bound metal

blade. Once it occurs, the equipment is thrown sideway or toward the
operator at great force and it may cause serious injury.
Kickback occurs particularly when applying the blade segment between 12
–

To avoid kickback:

Apply the segment between 8 and 11 o’clock;
Never apply the segment between 12 and 2 o’clock;
Never apply the segment between 11 and 12 o’clock and between 2 and
5 o’clock, unless the operator is well trained and experienced and does it at
his/her own risk;
Never use metal blades close to solids, such as fences, walls, tree trunks
and stones;
Never use metal blades vertically, for such operations as edging and
trimming hedges.
