OPERATION
WARNING:
To avoid burns from hot surfaces, never operate unit with
the bottom of the engine above waist level.
Hold the brushcutter with your right hand on the rear handle
and the your left hand on the “J” 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.
WARNING:
Always hold the brushcutter away from the body keeping
clearance between the body and the product. Any contact
with the housing can result in burns and/or other 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 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.
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.
CUTTING TECHNIQUE - BLADE
See Figure 14.
WARNING:
Extreme care must be taken when using blades to ensure
safe operation. Read the safety information for safe op-
eration 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, build-
ings or other immovable objects.
 Never use a blade after hitting a hard object without first in-
specting 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 TRIMMER
See Figures 15.
Hold the trimmer with your right hand on the rear handle
and your left hand on the “J” handle. Keep a firm grip with
both hands while in operation. Trimmer should be held at a
comfortable position with the rear handle about hip height.
Always operate trimmer at full throttle. Cut tall grass from
the top down. This will prevent grass from wrapping around
the shaft housing and string head which could cause dam-
age from overheating. If grass becomes wrapped around
the string head, STOP THE ENGINE, disconnect the spark
plug wire, and remove the grass. Prolonged cutting at partial
throttle will result in lubricant dripping from the muffler.
TO ADVANCE THE CUTTING LINE (REEL EASY
STRING HEAD)
Line advance is controlled by tapping the string head on
grass while running engine at full throttle.

Run engine at full throttle.
 Tap the knob on ground to advance line. The line advances
each time the knob is tapped. Do not hold the knob on
the ground.
