General Safety Instructions
WARNING!
■■When operating with a blade, make sure the handle
is positioned to provide you with maximum protection from contacting the blade. Always make sure the
handlebar is installed in accordance with the manufacturers instruction.
■■ALWAYS Shut off the engine immediately if a blade
binds in a cut. Push the branch or tree to ease the
bind and free the blade.
■■Beware of a coasting blade when brushcutting.
A coasting blade can injure while it continues to
spin after the throttle trigger is released or after the
engine is stopped.
■■NEVER use a cracked or warped blade: If a properly
installed blade vibrates, replace it with a new one and
re-check.

Units with adjustable carburetors must be readjusted for blade use, otherwise
serious engine damage can occur.
IMPORTANT!
Discard blades that are bent, warped, cracked, broken or damaged in any
way.Use a sharp blade. A dull blade is more likely to snag and thrust.
WARNING!
A standard grass trimmer unit with loop handle should NEVER be operated with blade-type attachments. For blade use,
the trimmer must be fitted with a bicycle-type handlebar or barrier bar that is located in front of the operator to reduce the
risk of the operator coming in contact with the cutting attachment. (Per ANSI B175.3). When using a blade, the unit must
be equipped with a harness or strap.

Shoulder Strap
Adjust the shoulder strap so the shoulder pad rests comfortably on the off-side
shoulder and the cutting path of the cutting attachment is parallel to the
ground. Tighten hanger screw.
WARNING!
Always wear a shoulder strap when operating this unit with a blade. A
shoulder strap is also recommended when using trimmer line.
NOTE:
Using a shoulder strap with a brush-cutter allows you to maintain proper
control of the unit and reduces fatigue during extended operation.
balance and adjust unit
1. Loosen harness clamp screw.
2. Put on harness and attach unit to harness.
3. Slide harness clamp up or down until unit balances with head approximately 50-75 mm (2 -3 in.) from the ground.
4. Tighten harness clamp screw.
5. Loosen Handle bar clamp screws, and position Handle bar for comfortable
operation.
6. Tighten Handle bar clamp screws securely.

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 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 object 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.
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!
Eleven
O’Clock
Handle Bar
A brushcutter’s handle bar helps prevent the operator from moving forward,
or the unit moving rearward, thus preventing inadvertent bodily contact with
the blade. ALWAYS KEEP THE HANDLE BAR SECURELY IN PLACE ON
THE UNIT!

UT

Rotation
OK To Cut
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 equipped 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.
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 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 (shaded area).
