Stihl FS 120 Instruction Manual page 17

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!
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.
Use the power tool like a scythe to cut
grass, i.e. sweep it to and fro in an arc.
Warning!
When cutting woody materials, use the
left side of the blade to avoid "kickout"
(blade thrust) situations.
Warning!
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 bystand -
ers. 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.) 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 diame -
ter, 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, result -
ing in personal injury. Use a circular saw
blade for such work.
Warning!
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 regu -
larly (when it has dulled noticeably).
Using the Circular Saw Blade
Circular saw blades are suitable for
thinning brush and cutting small trees up
to a diameter of 4 cm (1 1/2 in.). Do not
attempt to cut trees with larger
diameters, since the blade may catch or
jerk the trimmer / brushcutter forward.
This may cause damage to the blade or
loss of control of the power tool and
result in serious injury. Use a chain saw
for such work.
Warning!
To reduce the risk that the blade will
crack and / or break, avoid all contact
with stones, rocks or the ground.
Sharpen blades in a timely manner as
specified – dull teeth may cause the
blade to crack or shatter.
When a trimmer / brushcutter with a
circular saw blade is used to cut down
small trees, STIHL recommends that the
