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.
When a trimmer / brushcutter with a
circular saw blade is used to cut down
small trees, STIHL recommends that the
standard deflector be removed and
replaced by the special limit stop
deflector (see chapter on "Mounting the
Deflector"). This limit stop helps to keep
the unit positioned against the tree
during the cutting process.
Inexperienced users should place the
left side of the stop against the tree trunk
before beginning to cut. This will keep
the trimmer / brushcutter against the tree
during the cutting operation and will
reduce the risk of loss of control and
possible kickout (described above and
briefly again below).
Before starting the cut, accelerate the
engine up to full throttle. Perform cut
with uniform pressure. STIHL
recommends that the circular saw blade
be applied to the right of the tree, using
the non-shaded area of the blade, as
shown in the illustration above.
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).
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.
