Persons over the age of 16 years may however use the device for the purpose of being trained while under supervision of a qualied trainer. ● Use with the utmost care and attention. ● Operate only if you are in good physical condition. Perform all work calmly and carefully. The user has to accept liability for others. ● Never use this equipment after consumption of alcohol or drugs, or if feeling tired or ill. ● National regulation can restrict the use of the machine. Intended use of the machine ● This equipment is only intended for cutting grass, weeds, bushes, undergrowth. It should not be used for any other purpose such as edging or hedge cutting as this may cause injury. Personal protective equipment ● The clothing worn should be functional and appropriate, i.e. it should be tight- tting but not cause hindrance. Do not wear either jewelry or clothing which could become entangled with bushes or shrubs. ● In order to avoid either head-, eye-, hand-or foot injuries as well as to protect your hearing the following protective equipment and protective clothing must be used during operation. ● Always wear a helmet where there is a risk of falling objects. The protective helmet (1) is to be checked at regular intervals for damage and is to be replaced at the latest after 5 years. Use only approved protective helmets. ● The visor (2) of the helmet (or alternatively goggles) protects the face from ying debris and stones. During operation always wear goggles, or a visor to prevent eye injuries. ● Wear adequate noise protection equipment to avoid hearing impairment (ear muffs (3), ear plugs etc.). ● The work overalls (4) protect against ying stones and debris. We strongly recommend that the user wears work overalls. ● Gloves (5) are part of the prescribed equipment and must always be worn during operation. ● When using the equipment, always wear sturdy shoes (6) with a non-slip sole. This protects against injuries and ensures a good footing. Starting up the brushcutter ● Make sure that there are no children or other people within a working range of 15 meters (50 ft), also pay attention to any animals in the working vicinity. ● Before use always check the equipment is safe for operation: Check the security of the cutting tool, the throttle lever for easy action and check for proper functioning of the throttle lever lock. ● Rotation of the cutting tool during idling speed is not allowed. Check with your dealer for adjustment if in doubt. Check for clean and dry handles and test the function of the start/stop switch.4 Start the brushcutter only in accordance with the instructions. ● Do not use any other methods for starting the engine! ● Use the brushcutter and the tools only for such applications as specied. ● Only start the engine, after the entire assembly is done. Operation of the device is only permitted after all the appropriate accessories are attached! ● Before starting make sure that the cutting tool has no contact with hard objects such as branches, stones etc. as the cutting tool will revolve when starting. ● The engine is to be switched off immediately in case of any engine problems. ● Should the cutting tool hit stones or other hard objects, immediately switch off the engine and inspect the cutting tool. ● Inspect the cutting tool at short regular intervals for damage (detection of hairline cracks by means of tapping-noise test). ● If the equipment gets heavy impact or fall, check the condition before continuing work. Check the fuel system for fuel leakage and the controls and safety devices for malfunction. If there is any damage or doubt, ask our authorized service center for the inspection and repair. ● Operate the equipment only with the harness attached which is to be suitably adjusted before putting the brushcutter into operation. It is essential to adjust the harness according to the user size to prevent fatigue occurring during use. Never hold the cutter with one hand during use. ● During operation always hold the brushcutter with both hands. Always ensure a safe footing. ● Operate the equipment in such a manner as to avoid inhalation of the exhaust gases. Never run the engine in enclosed rooms (risk of gas poisoning). Carbon monoxide is an odorless gas. ● Switch off the engine when resting and when leaving the equipment unattended, and place it in a safe location to prevent danger to others or damage to the machine. ● Never put the hot brushcutter onto dry grass or onto any combustible materials. ● Always install the approved cutting tool guard onto the equipment before starting the engine. Otherwise contact with the cutting tool may cause serious injury. ● All protective installations and guards supplied with the machine must be used during operation. ● Never operate the engine with faulty exhaust mufer. ● Shut off the engine during transport. ● When transporting the equipment, always attach the cover to the metal blade. ● Ensure safe position of the equipment during car transportation to avoid fuel leakage. ● When transporting, ensure that the fuel tank is completely empty. ● When unloading the equipment from the truck, never drop the Engine to the ground or this may severely damage the fuel tank. ● Except in case of emergency, never drop or cast the equipment to the ground or this may severely damage the equipment. Refuelling ● Shut off the engine during refuelling, keep away from open ames and do not smoke. ● Avoid skin contact with mineral oil products. Do not inhale fuel vapor. Always wear protective gloves during refuelling. Change and clean protective clothing at regular intervals. ● Take care not to spill either fuel or oil in order to prevent soil contamination (environmental protection). Clean the brushcutter immediately after fuel has been spilt. ● Avoid any fuel contact with your clothing. Change your clothing instantly if fuel has been spilt on it (to prevent clothing catching re). ● Inspect the fuel cap at regular intervals making sure that it can be securely fastened and does not leak. ● Carefully tighten the fuel tank cap. Change location to start the engine (at least 3 meters away from the place of refuelling). ● Never refuel in closed rooms. Fuel vapors accumulate at ground level (risk of explosions). ● Only transport and store fuel in approved containers. Make sure the fuel stored is not accessible to children. ● Always refuel on stable at surface to avoid fuel spillage. p. 29
- Tool replacement 3 meters5 Method of operation ● Only use in good light and visibility. During the winter season beware of slippery or wet areas, ice and snow (risk of slipping). Always ensure a safe footing. ● Never cut above waist height. ● Never stand on a ladder. ● Never climb up into trees to perform cutting operation. ● Never work on unstable surfaces. ● Remove sand, stones, nails etc. found within the working range. Foreign particles may damage the cutting tool and can cause dangerous kick- backs. ● Before commencing cutting, the cutting tool must have reached full working speed. ● When using metal blades, swing the tool evenly in half-circle from right to left, like using a scythe. If grass or branches get caught between the cutting tool and guard, always stop the engine before cleaning. Otherwise unintentional blade rotation may cause serious injury. ● Take a rest to prevent loss of control caused by fatigue. We recommend to take a 10 to 20-minute rest every hour. ● Do not let the cutting tool touch on the ground during operation. Otherwise the cutting tool hit an object and may result in personal injury. ● Keep the metal blade parallel with the ground during operation. Cutting Tools ● Use an applicable cutting tool for the job in hand. Nylon cutting heads (string trimmer heads) are suitable for trimming lawn grass. Metal blades are suitable for cutting weeds, high grasses, bushes, shrubs, underwood, thicket, and the like. Never use other blades including metal multi-piece pivoting chains and ail blades. Otherwise serious injury may result. ● When using metal blades, avoid “Kickback” and always prepare for an accidental kickback. See the section “Kickback”. Kickback (blade thrust) ● Kickback (blade thrust) is a sudden reaction to a caught or bound metal blade. Once it occurs, the equipment is thrown sideway or toward the operator at great force and it may cause serious injury. ● Kickback occurs particularly when applying the blade segment between 12 and 2 o’clock to solids, bushes and trees with 3 cm or larger diameter. ● To avoid kickback: – Apply the segment between 8 and 11 o’clock; – Never apply the segment between 12 and 2 o’clock; – Never apply the segment between 11 and 12 o’clock and between 2 and 5 o’clock, unless the operator is well trained and experienced and does it at his/her own risk; – Never use metal blades close to solids, such as fences, walls, tree trunks and stones; – Never use metal blades vertically, for such operations as edging and trimming hedges. Vibration ● People with poor circulation who are exposed to excessive vibration may experience injury to blood vessels or the nervous system. Vibration may cause the following symptoms to occur in the ngers, hands or wrists: “Falling asleep” (numbness), tingling, pain, stabbing sensation, alteration of skin color or of the skin. If any of these symptoms occur, see a physician! ● To reduce the risk of “white nger disease”, keep your hands warm during operation and well maintain the equipment and accessories. Maintenance instructions ● Have your equipment serviced by our authorized service center, always using only genuine replacement parts. Incorrect repair and poor maintenance can shorten the life of the equipment and increase the risk of accidents. ● The condition of the cutter, in particular of the cutting tool of the protective devices and also of the harness must be checked before commencing work. Particular attention is to be paid to the metal blades which must be correctly sharpened. ● Turn off the engine and remove spark plug connector when replacing or sharpening cutting tools, and also when cleaning the cutter or cutting tool. Caution: Kickback Diagrammatic gure Diagrammatic gure6 Never straighten or weld damaged cutting tools. ● Pay attention to the environment. Avoid unnecessary throttle operation for less pollution and noise emissions. Adjust the carburetor correctly. ● Clean the equipment at regular intervals and check that all screws and nuts are well tightened. ● Never service or store the equipment in the vicinity of naked ames. ● Always store the equipment in locked rooms and with an emptied fuel tank. ● When cleaning, servicing and storing the equipment, always attach the cover to the metal blade.

However, if oil pipe becomes extremely dirty, visibility may be lost, and oil level will have to be checked against stepped section on inside of oil pipe. ● You may need to rell oil approximately every 10 operating hours (every 10 refuellings). If the oil changes in color or mixes with dirt, replace it with new one. (For the interval and method of replacement, refer to P 23.)
BEFORE START OF OPERATION
(1) Keep the engine level, and detach the oil cap. (2) Fill with oil to upper limit mark. Use oil bottle when lling. (1) (2) Recommended oil: SAE 10W-30 oil of API Classication, Class SF or higher (4-stroke engine for automobile) Oil volume: Approx. 0.10L NOTE: ● If the engine is not positioned as illustrated on a horizontal surface, an inaccurate indication of oil level may occur and oil may be overlled. Filling oil above the upper limit may cause oil contamination and/or white smoke. Replacement of oil: “Oil cap” ● Remove dust or dirt near the oil rell port, and detach the oil cap. ● Keep the detached oil cap free of sand or dust. Otherwise, any sand or dust adhering to the oil cap may cause irregular oil circulation or wear on the engine parts, which will result in troubles. (3) Securely tighten the oil cap. Insufcient tightening may cause oil leakage.15 Refuelling
● Shut off the engine before refuelling, keep away from open ames and do not smoke. ● Loosen the tank cap (1) a little to release the tank pressure. ● Remove the tank cap, and refuel. DO NOT ll fuel more than fuel upper limit (3). ● Wipe the outside of the tank cap to prevent debris from entering into the fuel tank. ● After refuelling, securely tighten the tank cap. NOTE: ● If there is any aw or damage on the tank cap, replace it. ● The tank cap wears out in course of time. Replace it every two to three years. ● DO NOT put fuel in the oil ll port. NOTE: ● Do not replace oil with the engine in a tilted position. ● Filling with oil while engine is tilted leads to overlling which causes oil contamination and/or white smoke. After relling oil ● Wipe with a rag any spilled oil immediately. REFUELLING Handling of fuel It is necessary to handle fuel with utmost care. Fuel may contain substances similar to solvents. Refuelling must be performed in a sufciently ventilated room or in the open air. Never inhale fuel vapor, and keep fuel away from you. If you touch fuel repeatedly or for a long time, the skin becomes dry, which may cause skin disease or allergy. If fuel enters into the eye, clean the eye with fresh water. If your eye remains still irritated, consult your doctor. Storage period of fuel Fuel should be used within a period of 4 weeks, even if it is kept in a special container in a well-ventilated and shaded area. Otherwise, fuel may deteriorate in one day.
STORAGE OF MACHINE AND REFILL TANK
● Keep the machine and tank at a cool place free from direct sunshine. ● Never keep the fuel in a car. Fuel The engine is a four-stroke engine. Be sure to use an unleaded automobile gasoline 87 or higher octane ((R+M)/2). It may contain no more than 10% alcohol (E-10). Points for fuel ● Never use a gasoline mixture which contains engine oil. Otherwise, it will cause excessive carbon accumulation or mechanical troubles. ● Use of deteriorated oil will cause irregular start-up. (1) (2) (3)16

HOW TO START AND STOP ENGINE
Close the choke lever. Choke opening: ● Full closing in cold or when the engine is cold. ● Full or half opening if the engine is a bit warm, such as restarting engine just after stopping during warm-up operation.
Continue to push the primer pump (3) until fuel comes into the primer pump. (In general, 7 to 10 pushes.) If the primer pump is pushed excessively, an excess of gasoline returns to the fuel tank. (3) (1) (2)19 NOTE: ● Do not pull the throttle lever unnecessarily when the engine is not running. It may cause ooding of fuel in the engine, and may cause the engine difcult to start up. ● In case of ooding of the fuel, remove the spark plug and pull the starter handle slowly to remove excess fuel. Also, dry the electrode section of the spark plug. ● If the engine res and stops, or stops soon after starting, return the choke lever to the OPEN position, and pull the starter knob a few times again to start the engine. ● If the choke lever is left in the CLOSE position, and the starter knob merely pulled repeatedly, too much fuel will be sucked in, and the engine will become difcult to start. ● Do not race the engine in warm-up operation unnecessarily. B: Warm start
1) Keep the choke lever full open.
2) Push the primer pump repeatedly.
3) Keep the throttle lever at the idling position.
4) Pull the starter knob strongly.
You can also restart the engine while carrying the tool on your back. CAUTION: ● Make sure that the cutting tool is not touching while restarting. ● Do not pull the throttle lever when restarting. Otherwise the cutting tool starts rotating. Hold the handle with your right hand, and pull the starter knob strongly.
Make sure you have a rm footing. Hold the unit with your left hand and press it down rmly. CAUTION: ● Do not stand or kneel on the throttle cable. The internal wire may be pulled and the cutting tool may start rotating unintentionally. Do not open the throttle. Pull the starter knob gently until a certain resistance is felt. Then, return the starter knob, and pull it strongly. Never pull the rope to the full extension. Once the starter knob is pulled, never release your hand immediately. Hold the starter knob until it returns to its original point.
Once engine starts, set choke lever to the OPEN position. ● Open the choke lever gradually while checking the engine operation. Be sure to open the choke lever to the full in the end. ● In cold or when the engine is cooled down, never open the choke lever suddenly. Otherwise the engine may stop.
7) Warm-up operation
Continue warm-up operation for 2 to 3 minutes. NOTICE: ● Do not pull the throttle lever unnecessarily while the engine is not running. It may cause fuel leak from the air cleaner. If it happens, wipe leaked fuel off. Also, open the air cleaner cover and clean the element and the air cleaner plate.20
