To cut wild growth and scrub, lower the brush
knife down onto the growth to achieve a shred‐
ding effect – always keep the cutting attachment
below hip level during this process.
Exercise extreme caution when using this
method of cutting. The higher the cutting attach‐
ment is off the ground, the greater the risk of
injury from cuttings being thrown sideways.
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 diame‐
ter of more than 2 cm – use a circular saw
blade for such work.
–
Inspect the brush knife at regular short inter‐
vals for signs of damage. Do not continue
working with a damaged brush knife.
–
Resharpen the brush knife regularly and
whenever 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.
WARNING
To reduce the risk of blade damage, avoid con‐
tact 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.
