Resharpen the grass 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 attachment above waist
height.
Exercise extreme caution when using
this method of cutting. The higher the
cutting attachment is off the ground, the
greater the risk of injury from cuttings
being thrown sideways.
Use the brushcutter like a scythe (sweep
it to the right and left) at ground level
when cutting grass and thinning young
stands.
Warning! Improper use of a brush knife
may cause it to crack, chip or shatter –
risk of injury from thrown parts.
To reduce the risk of injury it is essential
to take the following precautions
–
Avoid contact with stones, rocks,
pieces of metal and other solid
foreign objects.
–
Never cut wood or shrubs with a
stem diameter of more than 2 cm –
use a circular saw blade for this
purpose.
–
Inspect the brush knife at regular
short intervals for signs of damage.
Do not continue working with a
damaged brush knife.
–
Resharpen the brush knife regularly
(when it has dulled noticeably) and
have it balanced if necessary
(STIHL recommends a STIHL
servicing dealer).
Circular Saw Blade
For cutting shrubs and trees:
Up to a stem diameter of 4 cm when
used on brushcutters.
Up to a stem diameter of 7 cm when
used on clearing saws.
Before starting the cut, accelerate the
engine up to full throttle. Perform cut
with uniform pressure.
Use circular saw blades only with a
matching limit stop of the correct
diameter.
To reduce the risk of blade damage,
avoid contact with stones and the
ground. Resharpen the blade properly in
good time – dull teeth may result in the
blade cracking and shattering and
causing serious injury.
When felling, maintain a distance of at
least two tree lengths from the next
felling site.
Risk of kickout
The risk of kickout is highest in the black
area of the blade: Do not use this area of
the circular saw blade for cutting.
There is also a risk of kickout when
using the lighter shaded areas of the
blade: These areas of the blade should
only be used by experienced operators
with specialized training.
STIHL recommends that you use the
non-shaded area of the circular saw
blade. Always start the cut with this area
of the blade.
