Using A Brushcutter Blade T272X
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 UNIT WITH A
DAMAGED BLADE!
n A blade-equipped unit must be
equipped with a bicycle-type
handlebar or barrier bar as well as
a harness or shoulder strap.
n Always make sure the cutting
attachment shield is properly
installed before operating this unit.
The blade rotates counter-clockwise. For
best performance and to minimize being
stuck 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 7 o'clock and 11
o'clock positions (as viewed from above).
DO NOT cut between the 11 o'clock and 5
o'clock positions. See Figure 5.

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
WARNING!
n When cutting wood with a blade,
feed the blade slowly.
Never strike or "slam" the spin-
ning blade against the wood.
n DO NOT use 2-tooth or non-
Shindaiwa approved 4-tooth
cutting blades with Shindaiwa
trimmers and brushcutters.
A brushcutter's handlebar helps prevent
the operator from moving forward or the
unit moving rearward; thus preventing
inadvertent bodily contact with the blade.
ALWAYS KEEP THE HANDLEBAR SE-
CURELY IN PLACE ON THE UNIT!
Shoulder Strap
A shoulder strap provides additional
protection against blade thrust. Plus, a
shoulder strap gives significant support
and comfort to help ensure safe and ef-
ficient operation.
When operating a blade equipped
trimmer, make sure the shoulder strap is
adjusted properly to the operator using
the unit.

O'Clock
Engine Operating Speeds
Operate the unit at full throttle while
cutting. 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 operate at
high speeds without a load.
n Avoid cutting at low engine speeds. Do-
ing so can lead to rapid clutch wear. In
addition, slow-speed operation tends to
cause grass and debris to wrap around
the cutting attachment.
Vertical cuts
Hold the trimmer with the blade at a 90°
angle to the ground so the blade's bottom
edge rotates toward the operator. Move
the blade from top to bottom through the
cut, and cut only with the bottom edge of
the blade. See Figure 5.
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
