Warning! Improper use of a brush knife
may cause it to crack, chip or shatter.
Thrown parts may injure the operator or
bystanders.
To reduce the risk of personal 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.
– 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 (by
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 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.
To reduce the risk of kickout, always
start the cut using the non-shaded area
of the the circular saw blade.
