Using A Brushcutter Blade T272X
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 sidewalks,
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 ob-
ject with a blade, always stop the
brushcutter and carefully inspect the
blade for damage. NEVER OPER-
ATE THE UNIT WITH A DAMAGED
BLADE!
 A blade-equipped unit must be
equipped with a bicycle-type handle-
bar or barrier bar as well as a har-
ness or shoulder strap.
 ALWAYS make sure the cutting at-
tachment shield is properly installed
before operating this 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.

To prevent possible engine damage, do
not allow the brushcutter to operate at
high speeds without a load.
 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.
WARNING!
When making vertical cuts, never allow
the blade to exceed waist height.
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 be-
tween 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 25.
Cut on the left
side of the blade.

OUTSIDE THE
PATH OF BLADE
ROTATION
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 26.

WARNING!
 When cutting wood with a blade,
feed the blade slowly. Never strike
or “slam” the spinning blade against
the wood.
 DO NOT use 2-tooth or non-
Shindaiwa approved 4-tooth cutting
blades with Shindaiwa trimmers and
brushcutters.
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 helps prevent
the operator from moving forward or the
unit moving rearward; thus preventing
inadvertent bodily contact with the blade.
ALWAYS KEEP THE HANDLEBAR
SECURELY IN PLACE ON THE UNIT!
Shoulder Strap
A shoulder strap provides additional protec-
tion against blade thrust. Plus, a shoulder
strap gives significant support and comfort
to help ensure safe and efficient operation.
When operating a blade equipped trimmer,
make sure the shoulder strap is adjusted
properly to the operator using the unit.
