Using A Brushcutter Blade C270
WARNING!
n Before working with a blade-
equipped unit, always inspect and
clean the area of objects that could
interfere with or damage the blade.
n Never use a blade near sidewalks,
fence posts, buildings or other
objects that could cause injury or
damage.
n Never use a blade for purposes other
than those for which it was designed.
n 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!
n A blade-equipped unit must be
equipped with a bicycle-type han-
dlebar or barrier bar as well as a
harness or shoulder strap.
n 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!
Brushcutter Handlebar
A brushcutter's handlebar or barrier bar
helps prevent the operator from mov-
ing forward or the unit moving rear-
ward; thus preventing inadvertent bodily
contact with the blade. ALWAYS KEEP
THE HANDLEBAR OR BARRIER BAR
SECURELY IN PLACE ON THE UNIT!
Brushcutter Shoulder Strap
A shoulder strap provides additional pro-
tection against blade thrust. Plus, a shoul-
der strap gives significant support and
comfort to help ensure safe and efficient
operation.
When operating a trimmer or brushcutter,
make sure both the handle and shoulder
strap are adjusted to the size of the opera-
tor using the unit.

Engine Operating Speeds
Operate the unit at full throttle while cut-
ting. Best fuel efficiency is obtained by
releasing the throttle when swinging back
after a cut.
n To prevent possible engine damage, do
not allow the brushcutter to run at high
speeds without a load.
n Avoid operating the engine 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 head.
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. See Figure 27.
WARNING!
n When cutting wood with a blade, feed
the blade slowly never strike or "slam"
the spinning blade against the wood.
n DO NOT use 2-tooth or non-
Shindaiwa approved 4-tooth cutting
blades with Shindaiwa trimmers and
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 bot-
tom edge of the blade. See Figure 28.
When making vertical cuts, never allow
the blade to exceed waist height.
