Risk of Kickout (Blade Thrust)
with Metal Cutting Blades
When using metal cutting tools (grass
cutting blade, brush knife, shredder
blade, circular saw blade) there is a risk
of kickout when the shaded area of the
rotating blade comes into contact with a
solid object like a tree trunk, branch, tree
stump, rock or similar. The machine is
thrown to the right or to the rear.
The risk of kickout is greatest when
the black area of the rotating blade
comes into contact with a solid object.

Grass Cutting Blade
Use for cutting grass and weeds only.
Sweep the brushcutter in an arc like a
scythe.
Warning! Improper use may damage
the grass cutting blade – risk of injury
from thrown parts.
Resharpen the cutting blade according
to instructions when it has dulled
noticeably.
Brush Knife
Suitable for cutting matted grass, wild
growth and scrub, thinning young stands
with a maximum stem diameter of 2 cm.
To reduce the risk of personal injury,
never attempt to cut thicker wood.
To cut wild growth and scrub, lower the
brush knife down onto the growth to
achieve shredding effect – do not use
the cutting tool above waist height.
Exercise extreme caution when using
this method of cutting. The higher the
cutting tool is off the ground, the greater
the risk of cuttings being thrown
sideways and causing injury.
Use the brushcutter like a scythe (sweep
it to the right and left) at ground level
when cutting grass and thinning young
stands.
