WARNING
■ CONTROLLING BLADE THRUST
Blade thrust can cause serious
personal injury. Carefully study this
section. It is important that you
understand what causes blade thrust,
how you can reduce the chance of
blade thrust and how you can remain
in control of the unit if blade thrust
does occur.
1. What causes blade thrust:
Blade thrust can occur when the moving
blade contacts an object that it cannot cut.
7
Download from Www.Somanuals.com. All Manuals Search And Download.
4. Safety precautions
This contact causes the blade to stop for
an instant and then suddenly move or
”bounce” away from the object that was
hit. The operator can lose control of the
unit and the blade can cause serious
personal injury to the operator or any
person nearby if the blade contacts any
part of the body.
2. How you can reduce the chance of
blade thrust:
(1) Recognize that blade thrust can
happen. By understanding and
knowing about bounce, you can help
eliminate the element of surprise.
(2) Cut fibrous weeds and grass only. Do
not let the blade contact materials it
cannot cut such as hard, woody vines
and brush or rocks, fences, metal, etc
(3) Be extra prepared for blade thrust if
you must cut where you cannot see
the blade making contact such as in
areas of dense growth.
(4) Keep the blade sharp. A dull blade
increase the chance of blade thrust.
(5) Avoid feeding the blade too rapidly.
The blade can bounce away from
material being cut if the blade is fed
faster than its cutting capability.
(6) Cut only from your right to your left.
(7) Keep your path of advance clear of
material that has been cut and other
debris.
3. How you can maintain the best
control:
(1) Keep a good, firm grip on the unit with
both hands. A firm grip can help
neutralize bounce. Keep your right
and left hands completely around the
respective handles.
(2) Keep both feet spread apart in a
comfortable stance and yet braced for
the possibility that the unit could
bounce. Do not overreach. Keep firm
footing and balance.

2.Keep the debris guard attached in place at all
times when the unit is operated.
TRIMMING GRASS AND WEEDS
• Always remember that the TIP of the line does
cutting. You will achieve better results by not crowding
the line into the cutting area. Allow the unit to trim at
its own pace.
1.Hold the unit so the head is off the ground and is tilted
about 20 degrees toward the sweep direction.
2.Use full throttle when cutting.
3.You can avoid thrown debris by sweeping from your
left to the right.
4.Use a slow, deliberate action to cut heavy growth. The
rate of cutting motion will depend on the material
being cut. Heavy growth will require slower action
than will light growth.
5.Never swing the unit so hard as you are in danger of
losing your balance or control of the unit.
6.Try to control the cutting motion with the hip rather
than placing the full workload on the arm and hands.
7.Take precautions to avoid wire, grass and dead, dry,
long-stem weeds from wrapping around the head
shaft. Such materials can stall the head and cause the
clutch to slip, resulting in damage to the clutch system
if repeated frequently.
ADJUSTING THE LINE LENGTH
• Your brushcutters is equipped with a semi- auto type
nylon line head that allows the operator to advance
the line without stopping the engine. When the line
becomes short, lightly tap the head on the ground
while running the engine at full throttle.
• Each time the head is bumped, the line advance
about 1 inch(25.4 mm). For better effect, tap the head
on bear ground or hard soil. Avoid bumping in thick,
tall grass as the engine may stall by overload.
