Kickback and Related Warnings
- Kickback is a sudden reaction to a pinched or snagged rotating wheel, backing pad, brush or any
other accessory. Pinching or snagging causes rapid stalling of the rotating accessory which in turn
causes the uncontrolled power tool to be forced in the direction opposite of the accessory’s rotation at
the point of the binding.
- For example, if an abrasive wheel is snagged or pinched by the workpiece, the edge of the wheel
that is entering into the pinch point can dig into the surface of the material causing the wheel to climb
out or kick out. The wheel may either jump toward or away from the operator, depending on direction
of the wheel’s movement at the point of pinching. Abrasive wheels may also break under these
conditions.
- Kickback is the result of power tool misuse and/or incorrect operating procedures or conditions
and can be avoided by taking proper precautions as given below:
o Never place your hand near the rotating accessory. Accessory may kickback over your hand.
o Do not position your body in the area where power tool will move if kickback occurs. Kickback will
propel the tool in direction opposite to the wheel’s movement at the point of snagging.
o Use special care when working corners, sharp edges etc. Avoid bouncing and snagging the
accessory. Corners, sharp edges or bouncing have a tendency to snag the rotating accessory and cause
loss of control or kickback.
Residual risks
Even if you use this tool correctly, there are always residual risks. The following hazards may arise in
connection with the structure and manufacture of this power tool:
- Hearing impairment if no suitable hearing protection is worn.
- Cuts if no suitable protective clothing is worn.
- Health damage resulting from vibration in the hands and arms if the device is used for a long
period of time or is not handled and maintained properly.
- Inhalation of particles
- Inhalation of exhaust gases
- Skin contact with oil / gasoline
- Inhalation of gasoline / oil vapors
- Contact with projected objects
- Burns when touching with hot surfaces
- Prolonged use of this product exposes the operator to vibration and can produce so-called "white
finger" disease. To reduce the risk, wear gloves and keep your hands warm.
- If any of the symptoms of "white finger syndrome" occur, seek immediate medical attention.
Symptoms of the "white finger" include numbness, loss of sensitivity, tingling, pain, loss of strength,

color changes or skin condition. These symptoms usually appear on the fingers, hands or wrists. Risk
increases at low temperatures.

Rocks or other debris could be thrown into eyes and face and cause serious personal injury.
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. You can avoid thrown debris by sweeping from your right to the left.
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 as 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.

8. Operation
-----------------------------------------------------------------------------------------------------
ADJUSTING THE LINE LENGTH
• Your brushcutter 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.
■METAL BLADE USAGE
NOTE
Choose a suitable recommended cutting attachment according to the object to be cut.
WARNING
• When sharpening, removing, or reattaching the blade, be sure to wear thick, sturdy gloves.
1. Check the bolt to fasten the blade and be sure the bolt has no fault, and no abrasion.
2. Be sure that the blade and the holder have been fastened according to instruction and the blade
turns smoothly without abnormal noise.
WARNING
• The rotating parts fastened incorrectly may cause serious accident to the operator.
• Make sure that the blade is not bent, warped, cracked, broken or damaged.
• If you find any error to the blade, discard it and change new one.
• By using the harness, hang the unit on your right side. Adjust the harness length so that the cutting
head may become parallel to the ground.
WARNING

• Make sure to use harness and cutting attachment guard. If not, it is very dangerous since you slip or
lose your balance.
■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.
9. Maintenance

surface and apply lubricant to avoid rust.

■REFILLING TRIMMING LINE
1. When the trimmer line is about to run out, you need to reload a new one. For replacement line, use a
diameter of 2.4mm (.095in). The spool is capable for a line up to 4m. Avoid using a larger line as it may
cut down the trimming performance.
2. Line up the arrow marks on knob and body of the head. Pull out the trimmer line from one side.
3. Insert new trimmer line through one of the eyelets to the other side.
4. Extend both ends of the line until their length matches.

9. Maintenance
-----------------------------------------------------------------------------------------------------
5. Wind up the line in the correct direction as indicated on the spool.
6. Leave the trimmer line around 160mm. Assembly is finished.
■AIR FILTER
• The air filter, if clogged, will reduce the engine performance. Monthly check and clean the filter
element in warm, soapy water as required. Dry completely before installing. If the element is broken or
shrunk, replace with a new one.
■FUEL FILTER
• When the engine runs short of fuel supply, check the fuel cap and the fuel filter for blockage.

■SPARK PLUG
• Starting failure and misfiring are often caused by a fouled spark plug. Clean the spark plug and check
that the plug gap is in the correct range. For a replacement plug, use the correct type
• Periodically clean the spark plug and check that the spark gap is in the correct range.
IMPORTANT
• Note that using any spark plugs other than those designated may result in the engine failing to
operate properly or in the engine becoming overheated and damaged.
• To install the spark plug, first turn the plug until it is finger tight, then tighten it a quarter turn more
with a socket wrench.
TIGHTENING TORQUE: 9.8~11.8 N.m
■MUFFLER
WARNING
• Inspect periodically, the muffler for loose fasteners, any damage or corrosion. If any sign of
exhaust leakage is found, do not use the brush cutter and have it repaired immediately.
• Note that failing to do so may result in the engine catching on fire.
10.Storage
-----------------------------------------------------------------------------------------------------
Aged fuel is one of major causes of engine starting failure. Before storing the unit, empty the fuel tank
and run the engine until it uses all the fuel left in the fuel line and the carburetor. Store the unit indoor
taking necessary measures for rust prevention.
11.Transportation
-----------------------------------------------------------------------------------------------------
1. When hand-carrying the product, cover over the cutting part if necessary, lift up the product and
