Using A Brushcutter Blade - Shindaiwa BP35 Owner's/Operator's Manual

Using a Brushcutter Blade

WARNING!
 Before working with a blade-
equipped unit, always inspect
and clean the area of objects that
could interfere with or damage the
blade.
 Never use a blade near side-
walks, fence posts, buildings or
other objects that could cause
injury or damage.
 Never use a blade for purposes
other than those for which it was
designed.
 Whenever you strike a hard object
with a blade, always stop the
brushcutter and carefully inspect
the blade for damage. NEVER
OPERATE THE BRUSHCUTTER
WITH A DAMAGED BLADE!
 Always make sure the cutting
attachment shield is properly
installed before operating the unit.
Blade Thrust
'Blade thrust' is a sudden sideways or
backward motion of the brushcutter.
Such motion may occur when the blade
jams or catches on an object such
as a sapling tree or tree stump. BE
CONSTANTLY ALERT FOR BLADE
THRUST AND GUARD AGAINST ITS
EFFECTS!
WARNING!
When cutting wood with a blade,
feed the blade slowly. Never strike or
"slam" a spinning blade against the
wood.

Engine Operating Speeds
Operate the engine at full throttle while
cutting. Best fuel efficiency is obtained
by releasing the throttle when swinging
back after a cut.
 To prevent possible engine damage,
do not allow the brushcutter to run at
high speeds without a load.
 Avoid operating the attachment at low
speeds. Doing so can lead to rapid
clutch wear. In addition, slow-speed
operation tends to cause grass and
debris to wrap around the cutting at-
tachment.
The blade rotates counter-clockwise. For
best performance and to minimize being
struck by debris, move the blade from
right to left while advancing on your
work.
Position the blade so cuts are made
between the blade's 8 o'clock and 10
o'clock positions (as viewed from above).
DO NOT cut between the 10 o'clock and
5 o'clock positions (shaded area). See
Figure 30.

WARNING!
DO NOT use 2-tooth or NON-
Shindaiwa approved 4-tooth cutting
blades with Shindaiwa brushcutters.
Vertical cuts
Hold the brushcutter with the blade at
a 90° angle to the ground so the blade's
bottom edge rotates toward the opera-
tor. Move the blade from top to bottom
through the cut, and cut only with the
bottom edge of the blade. See Figure 31.
WARNING!
When making vertical cuts, never
allow the blade to exceed waist
height.
Cut on the left side of the blade. KEEP
YOUR BODY OUTSIDE THE PATH
OF BLADE ROTATION
