Using A Brushcutter Blade; Blade Thrust - Shindaiwa T272 Instructions 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 ob-
ject with a blade, always stop
the brushcutter and carefully
inspect the blade for damage.
NEVER OPERATE THE UNIT
WITH A DAMAGED BLADE!
 A blade-equipped unit must be
equipped with a bicycle-type
handlebar or barrier as well as
a harness or strap.
 Always make sure the cutting
attachment shield is properly
installed before operating the
unit.
The blade rotates counter-clock-
wise. 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 9.

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!
Barrier Bar
A brushcutter's barrier bar helps
prevent the operator from moving
forward, or the unit moving rearward,
thus preventing inadvertent bodily
contact with the blade. ALWAYS
KEEP THE BARRIER BAR SECURE-
LY IN PLACE ON THE UNIT!
Shoulder Strap or Harness
A shoulder strap or harness provides
additional protection against blade
thrust. In addition, a shoulder strap
or harness gives significant support
and comfort to help ensure safe and
efficient operation.
When operating a unit equiped with
a blade, make sure both the handle/
barrier bar and shoulder strap or
harness are adjusted to the size of the
operator using the unit.
