Cutting Tools

1. Use a suitable cutting tool for your work. Always use the cutting tool guard properly suited for the cutting tool used.
2. Never use metal multi-piece pivoting chains, flail blades or blades not recommended in this manual. Otherwise serious injury may result.
3. When handling the metal blade, always wear gloves and put the blade cover on the blade. The blade can cut bare hands.
4. When using metal blades, avoid "kickback" and always prepare for an accidental kickback. See the section Kickback.
5. Before and after each operation, make sure that the cutting tool is attached securely. During operation, check the cutting tool for looseness in certain intervals.

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 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 11 and 1 o'clock to solids, bushes and trees with 3 cm or larger diameter.

To avoid kickback:

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

Vibration

Exposing to excessive vibration injures blood vessels or 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.
