(3) Warning / Attention
(4) Keep all children, bystanders and helpers
15 meters away from the brushcutter.
2 For safe operation
1.Read this manual carefully until you completely understand and can follow all safety notes, precautions, and operating instructions before using of the unit.
2.Do not operate this tool when you are tired, ill, or under the influence of alchohol, drugs, or medication.
3.Always wear eye or face protection and hearing protection.
4.Do not wear loose clothing, jewelry, short trousers, sandals, or go barefoot. Do not wear anything which might be caught by branches or moving part of the unit. Secure hair so it is above shoulder length.
5.Never start or run the engine inside a closed room or building. Exhaust gases contain dangerous carbon monoxide.
6.Before starting the engine, inspect the entire unit for loose fasteners and fuel leakage. Make sure that the cutting attachment is properly installed and securely fastened.
7.Be sure the blade guard is attached in place.
8.Fuel is highly flammable. Always keep open flames and sparks away from the unit and fuel depot. Do not smoke while refueling the unit or mixing fuel.
9.When refueling the unit, make sure to stop the engine and allow it to cool down. Wipe spilled fuel completely from the unit. Move
at least 3 meters away from fueling site before starting the engine.
10.Check the condition of working area to avoid any accident by hitting hidden obstacles such as stumps, stones, cans, or broken grass.
11.Keep bystanders and animals at least 15 meters away from the operating point, If you are approached, immediately stop the engine.
12.Keep firm footholds and balance at all times. Do not use the unit where footing is unsteady or slippery.
13.Keep cutting attachment below waist level. 14.Keep all parts of your body away from the
rotating cutting attachment and hot surfaces.
15.Warn the operator of the danger of blade thrust. (Kick back)
Blade thrust may occur when the spinning blade contacts a solid object in the critical area. A dangerous reaction may occur causing the entire unit and operator to be thrust violently. This reaction is called Kick back. As a result, the operator can lose control of the unit which can cause serious or fatal injury. Kick back is more likely to occur in areas where it is difficult to see the material to be cut.
16.When inspecting or servicing the unit, make sure to stop the engine and disconnect the spark plug as necessary.
17.Cover the blade when the transporting or storing the unit. Secure the unit before for
storage or transporting to prevent loss of fuel, damage or injury.
18.When replacing cutting attachment or other components, be sure to use the parts supplied or recommended by KOMATSU ZENOAH.
19.When the unit is turned off, make sure the cutting attachment has stopped before the unit is set down.
20.For units equipped with a clutch, be sure the cutting attachment stops turning when the engine idles.
21.Use only for tasks explained in the instruction handbook.
22.Discard blades that are bent, warped, cracked, broken or damaged in any way.
23.Instructions on stopping a coasting blade.
A blade can injure while it continues to spin after the engine is stopped or throttle control is released.
24.Stop the engine and blade before removing material that is blocking or entangling the cutting attachment.
25.Use a sharp blade. A dull blade is more likely to snag and thrust. Replace the fastening nut according to the manufacturer's instruction.
26.Cut only material recommended by the manufacturer. Do not let the blade contact material it cannot cut, such as rocks, metal etc.
27.Always wear safety boots, additionally a helmet is required if there is a risk of contact with falling objects.

3 Setup
■ HANDLE
•Install the handle to the shaft tube and clamp.
■ INSTALLING DEBRIS GUARD
•Attach the guard to the bracket on the main pipe and fix it with 2 screws.
■ INSTALLING CUTTING HEAD
1.While locking the gear shaft, by inserting the supplied tool into the upper holder on the gearbox, loosen and remove the hexagon nut (left-handed).
2.Then screw in the cutting head to the gear shaft over the holders. Hand-tighten it securely.
■ BALANCE UNIT
1.Put on strap and attach unit to strap.
2.Slide clamp up or down until unit balances with head aparting from the ground when using it.
4 Fuel
WARNING!!
•Gasoline is very flammable. Avoid smoking or bringing any flame or sparks near fuel. Make sure to stop the engine and allow it cool before refueling the unit. Select outdoor bare ground for fueling and move at least 3m (10ft) away from the fueling point before starting the engine.
•The Komatsu Zenoah engines are lubricated by oil specially formulated for air-cooled 2-cycle gasoline engine use. If Komatsu Zenoah oil is not available, use an anti-oxidant added quality oil expressly labeled for air-cooled 2-cycle engine use. (JASO FC GRADE OIL or ISO EGC GRADE)
•Do not use BIA or TCW (2-stroke water-cooling type) mixed oil.
RECOMMENDED MIXING RATIO
GASOLINE 50:OIL 1
•Exhaust emission are controlled by the fundamental engine parameters and components (eq., carburation, ignition timing and port timing) without addition of any major hardware or the introduction of an inert material during combustion.
•These engines are certified to operate on unleaded gasoline.
•Make sure to use gasoline with a minimum octane number of 89 RON (USA/Canada: 87AL)
•If you use a gasoline of a lower octane value than prescribed, there is a danger that the engine temperature may rise and an engine problem such as piston seizing may consequently occur.
•Unleaded gasoline is recommended to reduce the contamination of the air for the sake of your health and the environment.
•Poor quality gasolines or oils may damage sealing rings, fuel lines or fuel tank of the engine.
■ HOW TO MIX FUEL
IMPORTANT
Pay attention to agitation.
1.Measure out the quantities of gasoline and oil to be mixed.
2.Put some of the gasoline into a clean, approved fuel container.
3.Pour in all of the oil and agitate well.
4.Pour In the rest of gasoline and agitate again for at least one minute. As some oils may be difficult to agitate depending on oil ingredients, sufficient agitation is necessary for the engine to last long. Be careful that, if the agitation is insufficient, there is an increased danger of early piston seizing due to abnormally lean mixture.
5.Put a clear indication on the outside of the container
container to avoid mixing up with gasoline or other containers.
6.Indicate the contents on outside of container for easy identification.
■ FUELING THE UNIT
1.Untwist and remove the fuel cap. Rest the cap on a dustless place.
2.Put fuel into the fuel tank to 80% of the full capacity.
3.Fasten the fuel cap securely and wipe up any fuel spillage around the unit.
WARNING!!
1.Select bare ground for fueling.
2.Move at least 10feet (3meters) away from the fueling point before starting the engine.
3.Stop the engine before refueling the unit. At that time, be sure to sufficiently agitate the mixed gasoline in the container.
FOR YOUR ENGINE LIFE, AVOID;
1.FUEL WITH NO OIL(RAW GASOLINE) – It will cause severe damage to the internal engine parts very quickly.
2.GASOHOL – It can cause deterioration of rubber and/or plastic parts and disruption of engine lubrication.
3.OIL FOR 4-CYCLE ENGINE USE – It can cause spark plug fouling, exhaust port blocking, or piston ring sticking.
4.Mixed fuels which have been left unused for a period of one month or more may clog the carburetor and result in the engine failing to operate properly.
5.In the case of storing the product for a long period of time, clean the fuel tank after rendering it empty. Next, activate the engine and empty the carburetor of the composite fuel.
6.In the case of scrapping the used mixed oil container, scrap it only at an authorized repository site.
NOTE
