CONTROLLING BLADE BOUNCE
•
Kick out can cause serious personal injury.
Carefully study this section. It is important that
you understand what causes kick out, how you
can reduce the chance of kick out and how you can
remain in control of the unit if kick out does occur.
1.
What causes kick out :
•
Kick out can occur when the moving blade contacts
an object that it cannot cut. 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 kick out :
a. Recognize that kick out can happen. By
understanding and knowing about bounce, you can
help eliminate the element of surprise.
b. 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
c.
Be extra prepared for bounce if you must cut where
you cannot see the blade making contact such as in
areas of dense growth.
d. Keep the blade sharp. A dull blade increase the
chance of bounce.
e. 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.
f.
Cut only from your right to your left.
g.
Keep your path of advance clear of material that has
been cut and other debris.
3.
How you c an maintain the best control:
a.
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.
b.
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.
CUTTING WORK (LINE HEAD USAGE)
WARNING
1. Always wear eye protection such as safety
goggles. Never lean over the rotating cutting
head. Rocks or other debris could be thrown
into eyes and face and cause serious personal
injury.
2. Keep the debris guard in place at all times
when the unit is operated. Remember to
remove the cover from the line cutter (knife)
which locates on the debris guard. You can
adjust the line to the right length at any time
by lightly tapping the trimmer head against the
ground. The line cutter cuts off the excessive
line automatically.
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.
You can avoid thrown debris by sweeping from your
left to the right.
3. 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.
4.
Never swing the unit so hard as you are in danger of
losing your balance or control of the unit.
5.
Try to control the cutting motion with the hip rather
than placing the full workload on the arm and hands.
6.
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 brush cutter 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 advances
about 25 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.
