–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 tightfitting 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 flying 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 flying 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
–Please 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.

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 specified.
–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 shoulder harness attached which is to be suitably adjusted before putting the brushcutter into operation. It is
essential to adjust the shoulder 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 muffler.
–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.
–Remember to lift the entire equipment from the ground when moving the equipment. Dragging the fuel tank is highly dangerous and will cause damage and leakage of fuel, possibly causing fire.
Refueling
–Shut off the engine during refueling, keep away from open flames and do not smoke.
–Avoid skin contact with mineral oil products. Do not inhale fuel vapor. Always wear protective gloves during refueling. 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 fire).
–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 refueling).
–Never refuel in closed rooms. Fuel vapors accumulate at ground lever (risk of explosions).
–Only transport and store fuel in approved containers. Make sure the fuel stored is not accessible to children.

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.
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 flail blades. Otherwise serious injury may result.
–When using metal blades, avoid “kickback” and always prepare for an accidental kickback. See the section “Kickback” and “Kickback prevention.”
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 fingers, 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 finger 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 shoulder 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.

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 flames.
–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.
Observe the relevant accident prevention instructions issued by the relevant trade associations and by the insurance companies. Do not perform any modifications to the equipment as this will endanger your safety.
The performance of maintenance or repair work by the user is limited to those activities as described in the instruction manual. All other work is to be done by an Authorized Service Agent. Use only genuine spare parts and accessories released and supplied by MAKITA.
Use of non-approved accessories and tools means increased risk of accidents.
MAKITA will not accept any liability for accidents or damage caused by the use of non-approved cutting tools and fixing devices of cutting tools, or accessories.

BEFORE START OF OPERATION
Inspection and refill of engine oil
–Perform the following procedure, with the engine cooled down.
–Assure that the engine is on a flat horizontal surface and confirm if the oil level is between the lower or upper limit of the oil indicator.
–If the oil level is below the lower limit, remove the oil cap and add oil.
–The area surrounding the external marks is transparent, so the amount of oil inside can be checked without having to remove the oil cap. 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 refill oil approximately every 10 operating hours (every 10 refuelings).
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 22.)
Recommended oil: SAE 10W-30 oil of API Classification, 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 overfilled. 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 refill 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.
Oil |
Upper limit |
Lower limit
(1) Keep the engine level, and detach the oil cap.
(2) Fill with oil to upper limit mark. Use oil bottle when filling.
(3) Securely tighten the oil cap. Insufficient tightening may cause oil leakage.
13
Note
•Do not replace oil with the engine in a tilted position.
•Filling with oil while engine is tilted leads to overfilling which causes oil contamination and/or white smoke.
After refilling oil
– Wipe with a rag any spilled oil immediately.
REFUELING
Handling of fuel
It is necessary to handle fuel with utmost care. Fuel may contain substances similar to solvents. Refueling must be performed in a sufficiently 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.
Refueling
WARNING: Shut off the engine before refueling, keep away from open flames and do not smoke.
–Loosen the tank cap a little to release the tank pressure.
–Detach the tank cap, and refuel, discharging air by tilting the fuel tank so that the refuel port will be oriented upward. DO NOT fill fuel up to the top of the tank.
–Wipe the outside of the tank cap to prevent debris from entering into the fuel tank.
–After refueling, securely tighten the tank cap.
•If there is any flaw 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 fill port.
