  Inspect and clear the area of any hidden objects such as 

glass, rocks, concrete, fencing, wire, wood, metal, etc.

  Never use  blades near sidewalks, fencing, posts, build-

ings or other immovable objects.

  Never use a blade after hitting a hard object without first 

inspecting it for damage. Do not use if any damage is 
detected.

  The unit is used as a scythe, cutting from the right to the 

left in a broad sweeping action from side to side.

  Use only the Tri-Arc® blade. To install any other brand 

blade  or  cutting  head  to  this  brushcutter  can  result  in 
serious personal injury.

OPERATING THE BRUSHCUTTER

See Figures 19 - 20.

Hold the brushcutter with your right hand on the rear handle 
and the your hand on the “J” Barrier Handle. Keep a firm 
grip with both hands while in operation. Brushcutter should 
be held at a comfortable position with the rear handle about 
hip  height.  Maintain  your  grip  and  balance  on  both  feet. 
Position yourself so that you will not be drawn off balance 
by the kickback reaction of the cutting blade. 
Adjust  the  shoulder  harness  to  position  the  brushcutter 
at a comfortable operating position and to assure that the 
shoulder  harness  will  reduce  the  risk  of  operator  contact 
with the blade.

BLADE THRUST

Exercise  extreme  caution  when  using  the  blade  with  this 
unit. Blade thrust is the reaction that may occur when the 
spinning blade contacts anything it cannot cut. This contact 
may cause the blade to stop for an instant, and suddenly 
“thrust” the unit away from the object that was hit. This re-
action can be violent enough to cause the operator to lose 
control of the unit. Blade thrust can occur without warning 
if the blade snags, stalls, or binds. This is more likely to oc-
cur in areas where it is difficult to see the material being cut. 
For cutting ease and safety, approach the weeds being cut 
with the brushcutter from the right to the left. In the event 
an unexpected object or woody stock is encountered, this 
practice could minimize the blade thrust reaction. 

WARNING:

To avoid burns from hot surfaces, never operate unit with 
the bottom of the engine above waist level.
