Using the Grass Cutting Blade
The 8-tooth grass cutting blade is
recommended for cutting fern or reed.
Use the power tool like a scythe to cut
grass, i.e. sweep it to and fro in an arc.
Both types of grass cutting blade have to
be resharpened when all cutting edges
are dull.
!Warning!
When cutting woody materials, use the
left side of the blade to avoid "kickout"
(blade thrust) situations.
Using the Brush Knife
!Warning!
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.
Improper use of a brush knife may cause
it to crack, chip or shatter. Thrown blade
fragments may seriously or fatally injure
the operator or bystanders. To reduce
the risk of injury, avoid contact with hard
or solid foreign objects such as stones,
rocks or pieces of metal.
!
Warning!
When cutting young saplings or other
woody materials up to 2 cm (3/4") in
diameter, use the left side of the blade to
avoid "kickout" situations (see section
on “Risk of kickout (blade thrust) with all
rigid cutting blades”). Do not attempt to
cut woody material with a larger
diameter, since the blade may catch or
jerk the power tool forward. This may
cause damage to the blade or power tool
or loss of control of the power tool,
resulting in personal injury. Use a
circular saw blade for such work.
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.
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.
!
Warning!
To reduce the risk of serious or fatal
injury from blade breakage, never
attempt to use this blade to cut woody
materials.
!
Warning!
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.
!Warning!

intended to cut grass and weeds. It has
