WARNING! Additional safety precautions The following additional safety precautions should be observed by all users of chain saws: 1. Do not operate a chain saw when you are fatigued. 2. Use safety footwear; snug-fitting clothing; protective gloves; and eye, hearing, and head protection devices. 3. Use caution when handling fuel. Move the chain saw at least 10 feet (3 m) from the fueling point before starting the engine. 4. Do not allow other persons to be near the chain saw when starting or cutting with the chain saw. Keep bystanders and animals out of the work area. 5. Do not start cutting until you have a clear work area, secure footing, and a planned retreat path from the falling tree. 6. Keep all parts of your body away from the saw chain when the engine is running. 7. Before you start the engine, make sure that the saw chain is not contacting anything. 8. Carry the chain saw with the engine stopped, the guide bar and saw chain to the rear, and the muffler away from your body. 9. Do not operate a chain saw that is damaged, is improperly adjusted, or is not completely and securely assembled. Be sure that the saw chain stops moving when the throttle control trigger is released. 10. Shut off the engine before setting it down. 11. Use extreme caution when cutting small size brush and saplings because slender material may catch the saw chain and be whipped toward y o u or pull you off balance. 12. When cutting a limb that is under tension be alert for springback so that you will not be struck when the tension on the wood fibers is released. 13. Keep the handles dry, clean, and free of oil or fuel mixture. 14. Operate the chain saw only in well-ventilated areas. 15. Do not operate a chain saw in a tree unless you have been specifically trained to do so. 16. All chain saw service, other than the items listed in the owner's manual maintenance instructions, should be performed by MAKITA . (For example, if improper tools are used to remove the flywheel or if an improper tool is used to hold the flywheel in order to remove the clutch structural damage to the flywheel could occur and could subsequently cause the flywheel to burst.) 17. When transporting your chain saw, use the chain protection cover. 18. Low kickback bars and low kickback chains are designed to reduce the risk of kickback injury. Ask your MAKITA dealer about these devices. Read and follow all safety precautions in the owner's manual. Failure to follow instructions could result in serious injury. It is recommended to lend the chain saw only to people who are experienced in working with chain saws. Always hand over the Owner`s and Safety Manual. WARNING! This chain saw is capable of severe kickback that could result in serious injury to the operator. Do not operate this chain saw unless you have extraordinary cutting needs and experience in and special training for dealing with kickback. Chain saws with significantly reduced kickback potential are available. WARNING! Kickback may occur when the nose or tip of the guide bar touches an object, or when the wood closes in and pinches the saw chain in the cut. This contact may abruptly stop the saw chain and in some cases may cause a lightning fast reverse reaction, kicking the guide bar up and back towards the user, or push the guide bar back towards the operator. Kickback may cause you to lose control of the saw. As a chain saw user, you can take several steps to reduce the risk of a kickback and potential injury. A. With a basic understanding of kickback, you can reduce or eliminate the element of surprise. It is a sudden surprise that contributes to accidents. B. Keep a good firm grip on the saw with both hands, your right hand on the rear grip and your left hand on the tubular handle, when the engine is running. Use a firm grip with thumbs and fingers encircling the chain saw handles. A firm grip can neutralize kickback and help you maintain control of the saw. Don't let go! C. Make sure that the area in which you are cutting is free from obstructions. Do not let the nose of the guide bar contact the log, branch, or any other obstructions which could be hit while you are operating the saw. D. Do not overreach or cut above shoulder height. E. Follow manufacturer's sharpening and maintenance instructions for the saw chain. F. Only use replacement bars and chains specified by the manufacturer or the equivalent. 4 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 dangerous. 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. max. CKA 21O Maximum Computed Kickback Angle (CKA)* without using the chain brake when using the recommended bar and chain combinations (In this example the CKA is 21°). 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! Always use two hands when operating the chain saw! XXX.YYY.ZZZ 1 XXX.YYY.ZZZ Reduced Kickback Bar and Chain combination that has been evaluated with the power head to achieve kickback protection (according to ANSI and CSA standards). * 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. The operator WARNING! Minors should never be allowed to use a chain saw. Bystanders, especially children and animals should not be allowed in the area where a chain saw is in use (fig. 1). Never let the saw run unattended. Store it in a locked place away from children. Fill the fuel tank to 7/8 th full (see storing the saw). Do not lend your chain saw without this owner's manual. Be sure that anyone using your saw understands the information given. Proper use of a chain saw involves 1. the operator 2. the saw 3. the use of the saw. Physical Condition 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. 2 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. 5 Discription of symbols used on chain saws: CSA Z 62.1-95 and Z 62.3-96 Class 1C Compliance with CSA -Standards Compliance with ANSI -Standard ANSI B175.1-1991 C ® US LISTED 45M6 Chain Saw listed in accordance with American National Standard Safety Specifications for Gasoline Powered Chain Saws (ANSI B 175.1-1991).
