 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.
TRI-ARC

The Tri-Arc ® blade is suited only for thicker weeds and pulpy

to extend the life of the blade. Do not sharpen the Tri-Arc
®
