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 cutting attachment guard in place at all
times when the unit is operated.
TRIMMING GRASS AND WEEDS
• Always remember that the TIP of the line does cut-
ting. 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.
WARNING
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 understand-
ing and knowing about bounce, you can help elimi-
nate 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 can 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.
8. Operation
CUTTING METHOD
(a) Use the front left side cutting.
(b) Guide the blade from your right to left with it tilted
slightly to your left.
(c) When mowing a wide area, start working from your
left end to avoid interference of cut grass.
(d) The blade may be seized by weeds if the engine
speed is too low, or the blade cuts too deep into
weeds. Adjust the engine speed and cutting depth
according to the condition of object.
WARNING
• If the grass or other object gets caught in the blade,
or if the unit starts to shake or vibrate, turn off the
engine and check the whole unit. Change the blade if
it has been damaged.
• Turn off the engine
and make sure the
blade has completely
stop before checking
the blade, and
removing any object
got caught in.
