General Safety Precautions
The use of any chain saw may be hazardous. At full throttle chain speed can reach 45 mph (20 m/s). It is important that you read; fully understand and observe the following safety precautions and warnings. Read the owner’s manual and the safety instructions periodically.
WARNING !
Reactive forces, including kickback, can be dan- gerous. Careless or improper use of any chain saw may cause serious or fatal injury.

Have your MAKITA dealer show you how to operate your chain saw. Observe all applicable local safety regulations, standards and ordinances.
*The Computed Kickback Angle is a calculated value from energies measured on a test bench. It is not the angle of the guide bar moved upward in case of a
KICKBACK.

You must be in good physical condition and mental health and not under the influence of any substance (drugs, alcohol), which might impair vision, dexterity or judgment.

Contact of the guide bar tip with any object should be avoided! Tip contact may cause the guide bar to move suddenly upward and backward, which may cause serious injury!

WARNING !
Prolonged use of chain saws exposing the operator to vibrations may produce Whitefinger disease (Raynaud’s phenomenon). This phenomenon reduces the hand’s ability to feel and regulate temperature, produces numbness and burning sensations and may cause nerve and circulation damage and tissue necrosis.
All MAKITA saws are therefore provided with an antivibration system which is essential for those using chain saws on a regular or sustained basis. Antivibration systems do not guarantee that you will not sustain Whitefinger disesase, however, they reduce this danger considerably. Nevertheless, continual and regular users should observe their hands and fingers and in case of any abnormal symptoms, seek medical advice immediately.
