Precautions
Relating to Work
WARNING!
When cutting small trees
with a blade, feed the blade
slowly—never strike or “slam”
the spinning blade against the
tree trunk.
DO NOT use 2-tooth
(lawnmower type) cutting
blades. Use only Shindaiwa
approved blades with your
Shindaiwa brushcutter. Using
a blade not authorized by
Shindaiwa may result in
serious injury.
Avoid blade thrust by keeping the
blade in view during operation.
Watch your cut at all times.
Cut ONLY small trees and/or
branches with the left side of the
blade between the 8 o’clock and
10 o’clock positions as shown in
Figure 28. Avoid cutting with any
other part of the blade. When
cutting brush, sweep the blade
from right to left, always keeping
the blade well in front. It is
recommended that the blade be
tilted down slightly to help keep
debris from accumulating on the
edge of the blade.

OK To Cut
Blade thrust will occur without
warning if the blade snags, stalls,
or binds in the cut. A dull blade is
more likely to thrust than a sharp
one because a sharp blade tends to
bite into the cut while a dull blade
tends to bounce away.
When using a blade, stay away
from fences and buildings. Watch
for stakes, wires, and other objects
that can cause kick back or that
can wrap around the blade.
DO NOT overreach. Move to
a comfortable position before
starting a cut, and maintain your
balance at all times.
Keep the engine at maximum
throttle during the cut. Apply just
enough feed pressure to maintain
engine speed without wasting
fuel or causing unnecessary wear.
Avoid extended operation at low
speeds to prevent clutch slippage.
Excessive clutch slippage will
cause premature wear of clutch
components.
If the blade strikes a solid object
or if abnormal vibration develops,
stop cutting immediately, stop the
engine, and inspect the blade. If
the blade is bent, warped, cracked,
broken or damaged in any way,
replace it with a sharp blade.
Small trees usually can be felled
with a single cut. Use the
8 o’clock-to-10 o’clock cutting
zones of the blade to avoid blade
thrust.
If the blade snags or binds in
a cut, STOP the engine before
proceeding to clear the blade from
the cut.
