OPERATION
TRI-ARC® BLADE
The TRI-ARC® blade is suited only for thicker weeds and
pulpy stalks. When the blade becomes dull, it can be
turned over to extend the life of the blade. Do not sharpen
the TRI-ARC® blade.
Use only TRI-ARC® blade, part number AP04105, available
at your local retailer.
CUTTING TECHNIQUE - BLADE
WARNING:
Extreme care must be taken when using blades to
ensure safe operation. Read the safety information for
safe operation using the blade, refer to “Specific Safety
Rules for Brushcutter and Blade Use” earlier in this
manual.
■ Always hold brushcutter on your right side with both
hands when operating. Use a firm grip on both handles.
■ 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.
■ 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,
buildings 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.
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
reaction 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 occur 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.
OPERATING THE BRUSHCUTTER
See Figures 19 and 20.
Hold the brushcutter with the right hand on the rear handle
and the left 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 trigger 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.
