Risk of Kickout (Blade Thrust)
with All Rigid Cutting Blades
!Warning!
Kickout (blade thrust) is the sudden and
uncontrolled motion towards the
operator's right or rear that can occur
when the shaded area of a rotating
blade comes in contact with a solid rigid
object like a tree, rock, bush or wall. The
rapid counterclockwise rotation of the
blade may be stopped or slowed, and
the cutting attachment may be thrown to
the right or to the rear.
This kickout (blade thrust) may cause
loss of control of the power tool and may
result in serious or fatal injury to the
operator or bystanders. To reduce the
risk of injury, extreme caution should be
used when cutting with the shaded area
of any rigid blade.
Using the Grass Cutting Blade
All kinds of grass and weeds can be
easily cut with the grass cutting blade.
The power tool is swept in an arc similar
to a scythe.
!Warning!
To reduce the risk of serious or fatal
injury from blade breakage, never
attempt to use this blade to cut woody
materials.
The 4-tooth grass cutting blade is
intended to cut grass and weeds. It has
4 cutting knives with cutting edges on
both sides, i.e. front and rear. When the
cutting edges on one side become dull,
the blade can be turned over to utilize
the cutting edges on the other side.
The 8-tooth grass cutting blade is
recommended for cutting fern or reed.
Both types of grass cutting blade have to
be resharpened when all cutting edges
are dull.
Using the Brush Knife
When fitted to the power tool, the brush
knife is suitable for applications ranging
from cutting matted grass to clearing
weeds, wild growth and scrub.
To cut wild growth and scrub, lower the
rotating brush knife down onto the
growth to achieve a chopping effect –
but keep the tool below waist height at
all times.
Exercise extreme caution when using
this method of cutting. The higher the
cutting attachment is off the ground, the
greater the risk of loss of control and of
cuttings being thrown sideways.
