Owner manual 11

 EQUIPPING THE SHAWL BAND(F12)

1. Equip the attached shawl band.(F12)

2. Turn on the engine, return the throttle lever to the lowest speed

position, and put the shawl band hook to the hanging part of the machine.

3. Adjust the length of the shawl band so that the blade is parallel to the ground in the working position. In order to prevent slack during operation, turn up the extra part of the band from the buckle.

 CUTTING OPERATION

METAL BLADE USAGE

 Always cut by guiding the head from your right to left.

 A metal blade cuts best with the outer 1/3. Use that area for cutting shrubs, plus tough and thick weeds. For cutting young grass you can use the outer 2/3 of the blade.

 Adjust the engine speed according to what you are cutting. Cut young grass at middle speed. Cut shrubs or tough and thick weeds at high speed.

(1) For branches and trees

(2) For grass and weeds

(3) Direction of cutting

(4) Direction of rotation

IMPORTANT

Operating at low speed makes it easier for grass, weeds or twigs to become caught up in the blades. And also it makes the shaft and clutch wear down more quickly.

NYLON CUTTER USAGE

 Using nylon cord consumes more power. Please note that the engine rotation speed in operation should be

50% more than when using the metal blade.

The nylon cutter cuts grass with the power of cord rotation. If you try to cut grass with the same length of cord for any time, rotation speed becomes lower due to resistance and you cannot cut well. In case of high resistance, remove the nylon cutter from grass, increase the rotation speed and cut a small amount of grass at one time.

 If you try to cut grass by swinging the brush cutter in the reverse way (from left to right), cut pieces fly in from the body. You can avoid getting your clothes dirty.

Owner manual 12

8. MAINTENANCE

AFTER 25 HOURS OF USE

 BLADE

 Sharpen each cutting edge and make sure the bottom corner is rounded. (F13)

 Do not cool the blade with water when using a grinder.

It may cause cracks on blade.

 AIR CLEANER

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. (F4)

(1) Cover

(2) Element

(3) Screen

(4) Body

IMPORTANT

A clogged air filter may increase fuel consumption while cutting down the engine power.

Operating the brush cutter without the air filter or with a deformed filter element will quickly ruin the engine.

 FUEL FILTER

Take the filter out of the fuelling port using a small wire hook. Disconnect the filter assembly from the fuel pipe and unhook the retainer to disassemble it. Clean the components with gasoline.

IMPORTANT

A clogged fuel filter may cause poor acceleration of the engine.

 SPARK PLUG

Remove and inspect the spark plug and clean the electrodes as necessary.

The spark gap should be adjusted to 0.6-0.7mm. (F15)

Owner manual 13

 INTAKE AIR COOLING VENT

 Check the intake air-cooling vent and the area around the cylinder cooling fins. Remove any waste, which has attached itself to the brush cutter.

IMPORTANT

 Note that failing to do so could cause the muffler to become overheated.

And that this in turn could cause the brush cutter to catch fire.

GEAR CASE

Apply multi-purpose grease after every 25 hours of use.

Remove the cutter holders to arrange for old grease to exit. (F16)

AFTER 100 HOURS OF USE

 MUFFLER

Remover the muffler, insert a screw driver into the entrance and wipe away any carbon build up. Wipe away any carbon build up on the muffler exhaust vent at the same time.

2. Tighten all screws, bolts, and fittings.

Check to see if any oil or grease has worked its way between the clutch lining and drum, and if it has, wipe it away using oil-free, lead-free gasoline.

4. Remove the float cabin of carburetor and clean the inside.

 ADJUSTING CARBURETOR

IMPORTANT

A wrong adjustment may cause damage to your unit. If the engine does not run well after adjusting the carburetor, please contact the shop where you purchased the product.

 IDLE ADJUSTMENT SCREW (F17)

Owner manual 14

This is the screw to adjust the engine rotation when the throttle lever is set to the lowest speed position. If you turn right (clockwise), rotation increases, and left (counterclockwise) it decreases. If the blade continues to rotate or engine stops when you return the throttle lever completely to the original position, make a readjustment.

(1) Idle adjustment screw

(2) High

(3) Low

MAINTENANCE BEFORE STORAGE

When brushing off dirt from the machine, check for damage or loose parts. If you find anything unusual, repair it before you use it again.

2. Drain fuel from the tank, and loosen the drain screw of the float cabin to empty completely, turn on the engine, and leave it running until it stops naturally.

3. Remove the spark plug and put in 1-2cc of 2-stroke cycle oil in the engine. Draw the starter rope 2-3 times, put the plug back, and stop it at the contraction position.

4. Apply anti-rust oil to the metal parts such as the throttle wire, put the cover on the blade, and keep it indoors, avoiding dampness.
