Intended use of machine
This machine is only intended for cutting grass, weeds, bushes, and undergrowth. Never use the machine for any other purpose such as edging or hedge cutting. Use for unintended purposes may result in serious injury.

Personal protective equipment

  1. Always wear heavy, long pants, sturdy boots, gloves, and a long-sleeve shirt. Do not wear loose clothing, jewelry, short pants, sandals, or go barefoot. Secure hair so it is above shoulder level.
  2. Always wear a helmet where there is a risk of falling objects.
  3. Always wear protective goggles to protect your eyes from injury when using the machine.
    The goggles must comply with ANSI Z87.1 in the USA, EN 166 in Europe, or AS/NZS 1336 in Australia/New Zealand. In Australia/New Zealand, it is legally required to wear a face shield to protect your face, too. It is an employer’s responsibility to enforce the use of appropriate safety protective equipment by the tool operators and by other persons in the immediate working area.
  4. Wear ear protection, such as ear muffs. Exposure to noise can cause hearing loss.
  5. Always wear sturdy shoes with a non-slip sole. This protects your feet against injuries and ensures a good footing.
  6. Wear a dust mask as necessary.

Preparation before use

  1. Before use, always check the machine is safe for operation:
    — Check for fuel leaks.
    — Make sure all fasteners are in place and secure.
    — Replace damaged parts.
    — Make sure the cutting tool is properly installed and securely fastened.
    — Make sure the cutting tool guard is properly attached in the position as described in this manual.
    — Check the throttle trigger, lock-off lever, and another control switch for smooth action and proper function.
    — Clean the handles for proper control of the machine.
    — Make sure the handles are installed as described in this manual.
    Failure to follow those instructions may cause serious injury.
  2. Use a sharp blade. Discard blades that are bent, warped, cracked, broken, chipped, or damaged in any way. A dull blade is more likely to snag and kick back.
  3. Always use all required parts for fixing the blade properly. Improper fixing parts can cause the blade to fly off and seriously injure the operator and/or bystanders.

Refueling

  1. Stop the engine before refueling. Keep away from open flames and sparks. Never smoke during refueling. Otherwise, fire and/or explosion may result.
  2. Refuel outdoors. Refueling in a closed room can cause an explosion of fuel vapor.
  3. Avoid contact with fuel or engine oil. Do not inhale fuel vapor. If fuel or oil spills, wipe it off from the machine and/or ground immediately.
    If fuel spills on your clothes, change them immediately to prevent them from catching fire.
  4. After refueling, carefully tighten the fuel tank cap and check for fuel leaks. Move at least 3 m (10 feet) away from the fueling source and site before starting the engine.
  5. Only transport and store fuel in approved containers.
    Keep children away from the stored fuel.

Starting up the brushcutter

  1. Keep children, bystanders and pets at least 15 m (50 feet) away, when starting up or using the machine. Additionally, bystanders should wear eye protection, as there is still a risk of injury from thrown objects. Otherwise, bystanders’ unexpected action or blade kickback may cause serious injury to the operator and/or bystanders.
  2. Start and operate the machine only outdoors in a well-ventilated area. Operation in a confined or poorly ventilated area can result in death due to suffocation or carbon monoxide poisoning.
  3. 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.
  4. If the cutting tool rotates at idle, adjust the idle speed so that it stops at idle. Otherwise unintentional contact with moving cutting tools may result in serious injury.
  5. Stop the motor immediately if you notice any trouble.

Transportation

  1. Stop the motor during transport. Otherwise, an unintentional start-up may cause injury.
  2. When transporting the machine, always attach the cover to the cutting blade. Contact with bare blades results in injury.
  3. Ensure the safe position of the machine during car transportation to avoid fuel leakage.
  4. Lift the entire machine from the ground when carrying the machine. Dragging the machine causes fuel tank damage and fuel leakage, resulting in fire.

Operation

  1. Only use the machine in good light and visibility. Use in the dark or poor visibility areas may cause unexpected accidents.
  2. Avoid using the machine when it is hard to keep your balance, for example, working on a steep surface or windy day.
  3. During the winter season, beware of slippery or wet areas, ice and snow to avoid slipping.
  4. If you are approached, stop the motor.
    Otherwise, the rotating cutting tool may hit the bystander and result in serious injury.
  5. Clear the working area before operation.
    Remove all objects such as rocks, broken glass, nails, wire, or string, which can be thrown or become entangled in the cutting attachment. Foreign particles may damage the cutting tool and can cause dangerous kickback.
  6. To control the machine steadily, do the following during operation:
    — Hold the machine with both hands firmly on your right side.
    — Hang the machine on your shoulder(s) with the shoulder harness.
    — Ensure a safe footing. Never work on a ladder or in a tree.
    — Avoid over-reach.
    — Keep cutting tool below waist level.
    — Keep all parts of your body away from the rotating cutting tool and hot surface.
    Those actions reduce the risk of injury.
  7. If weeds or branches get caught between the cutting tool and guard, always stop the motor before clearing. Otherwise, unintentional blade rotation may cause serious injury.
  8. Never drop or throw the machine, unless an emergency. If the machine drops or hits something, immediately check for fuel leakage, safety devices, and other damages. Operating a  malfunctioned machine may cause injury and/or fire.
  9. Inspect the cutting tool frequently, or immediately after it hits a stone or other hard objects.
    If the cutting tool breaks during operation, the broken piece may fly and cause injury.
  10. Stop the motor when inspecting, cleaning, or replacing the cutting tool. Otherwise, the cutting tool may rotate unexpectedly and result in serious injury.
  11. Maintain proper control until the cutting tool stops completely when stopping the motor or releasing the throttle trigger. A coasting blade can cause injury.
  12. Before starting the cutting operation, wait until the cutting tool attains enough speed for cutting.
    It reduces the risk of kickback and entangling weeds.
  13. Take a rest to prevent loss of control caused by fatigue. We recommend taking a 10 to 20-minute rest every hour.
  14.  Stop the motor and place it in a safe location, when resting or leaving the machine. It prevents unexpected accidents.
  15. Do not touch the engine and its muffler or do not put them onto combustible materials, while the engine runs or just after stopping it, as they are hot. Burn and/or fire may result.

Cutting Tools

  1. Use a suitable cutting tool for your work.
    — Nylon cutting heads (string trimmer heads) are suitable for trimming lawn grass.
    — Metal blades are suitable for cutting weeds, high grasses, bushes, shrubs, underwood, thickets, and the like.
    Always use the cutting tool guard properly suited for the cutting tool used.
  2. When using a nylon cutting head, use only the flexible, nonmetallic line recommended in this manual. Never use wire or wire rope. They can break off and become a dangerous projectile.
  3. Never use metal multi-piece pivoting chains, flail blades, or blades not recommended in this manual. Otherwise, serious injury may result.
  4. When handling the metal blade, always wear gloves and put the blade cover on the blade.
    The blade can cut bare hands.
  5. When using metal blades, avoid “kickback” and always prepare for an accidental kickback.
    See the section Kickback.

Kickback (blade thrust)
Kickback (blade thrust) may occur when the spinning blade contacts an object that it does not immediately cut. It can be violent enough to cause the unit and/or operator to be propelled in any direction, and possibly lose control of the unit, resulting in serious injury. Kickback can occur without warning- ing if the blade snags, stalls, or binds and is more likely to occur in areas where it is difficult to see the material being cut.
Kickback occurs particularly when applying the blade segment between 12 and 2 o’clock to solids, bushes, and trees with a 3 cm or larger diameter.
► Fig.1

To avoid kickback:

  1. Apply the segment between 8 and 11 o’clock.
  2. Swing the tool evenly in a half-circle from right to left, like using a scythe. This allows the proper segment of the blade to contact plants to be cut.
  3. Never apply the segment between 12 and 2 o’clock.
  4. 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.
    ► Fig.2
  5. Never use cutting blades close to solids, such as fences, walls, tree trunks, and stones.
  6. Never use cutting blades vertically, for such operations as edging and trimming hedges.
  7. Avoid using the tool in areas where it is difficult to see the object being cut.

Vibration
Exposure to excessive vibration injures blood vessels or the nervous system of the operator and causes the following symptoms in the fingers, hands, or wrists: “Falling asleep” (numbness), tingling, pain, stabbing sensation, or 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 machine and accessories.

Maintenance

  1. Have your machine serviced by our authorized service center using only identical replacement parts. Use only identical spare parts and accessories supplied by MAKITA.
    Incorrect repair and poor maintenance can shorten the life of the machine and increase the risk of accidents.
  2. Never alter or remove any components of the machine. It may cause fire and/or serious injury.
  3. After use, clean the machine and check all screws and nuts for tightness.
  4. Check the condition of the cutting tool, cutting tool guard, and shoulder harness. The cutting blade must be sharp. Never straighten or weld damaged cutting tools.

Other instructions

  1. Always store the machine in locked rooms and with an emptied fuel tank.
  2. Pay attention to the environment. Avoid unnecessarily throttling operations for less pollution and noise emissions.
    Adjust the carburetor correctly.
  3. Do not operate the engine with faulty exhaust muffler.

First Aid

  1. In case of accident make sure that a first-aid box is available in the vicinity of the cutting operations. Immediately replace any item taken from the first aid box.
  2. When asking for help, give the following information:
    — Place of accident
    — What happened
    — Number of injured persons
    — Kind of injuries
    — Your name

Additional safety instructions

  1. To avoid accidents, leave more than 15m (50 ft) distance between operators when two or more operators work in one area. Also, arrange a person to observe the distance between operators. If someone or an animal enters the working area, immediately stop the operation.
  2. Only use the cutting tools that are marked with a speed equal to or higher than the speed marked on the tool.
  3. Be sure to remove the cover on the cutting blade before operation.
