Before using, please check the shoulder harness and confirm it is OK. Encounter danger,please stop the brush cutter immediately,and pull the quick- release latch tab, the brush cutter will be depart from your body.

Cutting with a nylon head
The CUT – OFF KNIFE will be on the right side of the debris shield.
If the brush cutter is equipped with an bump feet head in order to increase the length of the cutting line press the cutting head on the ground by guiding it downwards.
WARNING! The proper debris shield must be in place on the unit when nylon cutting line is used. The cutting line can flap around if too much line is exposed. Always use the plastic debris shield with cut-off knife when using nylon cutting heads.
For nearly all cutting, it is good to tilt the line head so that contact is made on the part of the line circle where the line is moving away from you and the debris shield.

WARNING &DANGER
Tilting the head to the wrong side will shoot the debris TOWARDS you. lf the line head is held flat to the ground so that cutting occurs on the whole line circle, debris will be THROWN at you, drag will slow the engine down, and you will use up a lot of line.

WARNING &DANGER
Never use wire or wire-reinforced line in place of nylon trimmer line. Load your nylon line cutting head only with nylon trimmer line of the proper diameter.

WARNING &DANGER
Use extreme caution when operating over bare spots and gravel, because the line can throw small rock particles at high speeds.
Debris shields on the unit cannot stop objects which bounce or ricochet off hard surfaces.

Cutting with a blade
There are many different types of blades, however the two most commonly used are the following.
BRUSH CUTTER BLADE is used for cutting brush and weeds up to 3/4” in diameter.
DANGER! DO NOT TOUCH THESE TYPES OF OBJECTS WITH BLADE: Utility wires, metal stakes, rubber, rocks, masonry, fences.
NEVER USE A BRUSH CUTTER FOR CUTTING TREES.
Do not cut with dull, cracked or damaged metal blade.
Before cutting growth, inspect for obstructions such as boulders, metal stakes or strands of wire from broken fences. If an obstruction cannot be removed, mark its location so that you can avoid it with the blade. Rocks and metal will dull or damage a blade. Wires can catch on the blade head and flap around or be thrown into the air.
Blade thrust is the reaction which 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 reaction can be violent enough to cause the operator to lose control of the unit. Blade thrust may occur without warning if the blade snags, stalls or binds. This is more likely to occur in areas where it is difficult to see the material being cut. For cutting ease and safely, approach the weeds being cut from the right to the left,in the event that an unexpected object or woody stock is encountered,this could minimise the blade thrust reaction.

Maintenance and care

Refilling trimming line

1. For replacement line, use a diameter of up to 3mm. The spool is capable for a line up to 6m(20ft) on the 10cm(4”) head. Avoid using a larger line as it may cut down the trimming performance.
   For safety reasons, do not use metal reinforced line.

2. Pinch the slotted area on the both sides of the spool housing to unhook the bottom cap.

3. Take out the spool and pull off the old line. Put one end of new line through the spool holes and pull it until the length is equal between each part of the line.

4. Wind up the line in the correct direction as indicated on the spool.

5. Hook each end of the line in the slot on the edge of the spool, and then put the ends through the eyelets on the housing. Make sure that the spring and the washers are in place.

6. While holding the spool against the housing, pull the line ends to release them from the slot.

7. Line up the slot on the bottom cap with the hook on the housing, press the cap against the housing until it clicks.
   Fast winding thread heads (not included with all models): Align the spool holes with the corresponding head holes, align the two ends of the cutting thread and rotate the head by winding the cutting thread.

Blade (Picture H)

• Check the blade and the fasteners for looseness, cracking, or bending.
• Check the cutting edges and reform with a flat file
  1. Keep the end corner sharp.
  2. Round the root of the edge, using round file.
  3. Do not use water when using a grinder.
• It is recommended that filing should be done by professionals.
• Especially regarding filing the saw blade, Leave it to the professionals.

WARNING: Make sure that the engine has stopped and is cool before performing any service to the machine. Contact with moving cutting head or hot muf-fler may result in a personal injury.

Air Filter
Accumulated dust in the air filter will reduce engine efficiency. Increase fuel consumption and allow abrasive particles to pass into the engine. Remove the air filter as Often as necessary to maintain in a clean condition.
Light surface dust can readily be removed by tapping the filter. Heavy deposits should be washed out in suitable solvent.
Remove filter cover by loosening air filter cover knob.

Adjusting the Carburettor
Do not adjust carburettor unless necessary.
If you have trouble with the carburettor, see your dealer. Improper adjustment may cause engine damage and void warranty.

• When filter is dirty, replace the filter.
• When the inside of the fuel tank is dirty, it can be cleaned by rinsing the tank out with gasoline.

Checking the spark plug (Picture J)
Do not attempt to remove the plug from a hot engine in order to avoid possible damage to the threads. Clean or replace the plug if fouled with heavy oily deposits.
Replace the plug if the center electrode is worn rounded at the end.

Spark plug gap: 0.6-0.7mm

Gear Case (Picture K)

• The reduction gears are lubricated by a special angled transmission grease, in the gear case. Supply new grease every 25 hours of use or more often de-pending on the job condition.
• Remove the bolt of the grease nipple and the bolt opposite side of the grease nipple. Install new grease into the grease nipple to arrange for old grease to exit from the opposite side.

Muffler
Inspect periodically, the muffler for loose fasteners, any damage or corrosion. If any sign of exhaust leakage is found, stop using the machine and have it repaired immediately.
Note that failing to do so may result in the engine catching on fire.

PROCEDURES TO BE PERFORMED AFTER EVERY 100 HOURS OF USE

1. Remove the muffler, insert a screwdriver into the vent, and wipe away any carbon build-up. Wipe away any carbon build-up on the muffler exhaust vent and cylinder exhaust port at the same time.
