SAFETY PRECAUTIONS FOR CHAIN SAW USERS (ANSI B175.1-2000, Annex C. CAN/CSA-Z62.1-03)

2-1. KICKBACK SAFETY PRECAUTIONS

WARNING

Kickback may occur when the nose or tip of the guide bar touches an object, or when the wood closes in and pinch- es the saw chain in the cut. If bar tip makes contact with something it may cause a lightning-fast reverse reaction, kicking the guide bar up and back towards the operator. Pinching the saw chain along the top of the guide bar may push the guide bar rapidly back towards the operator. Either of these reactions may cause you to lose control of the saw, which could result in serious personal injury. Do not rely exclusively upon the safety devices built into your saw. As a chain saw user, you should take several steps to keep your cutting jobs free from accident or injury.

1.With a basic understanding of kickback, you can reduce or eliminate the element of surprise. Sudden surprise contributes to accidents.

2.Keep a good firm grip on the saw with both hands, the right hand on the rear handle, and the left hand on the front handle, when the engine is running. Use a firm grip with thumbs and fingers encircling the chain saw handles. A firm grip will help you reduce kickback and maintain control of the saw. Don’t let go.

3.Make sure that the area in which you are cutting is free from obstructions. Do not let the nose of the guide bar contact a log, branch, or any other obstruction which could be hit while you are operating the saw.

4.Cut at high engine speeds.

5.Do not overreach or cut above shoulder height.

6.Follow manufacturer’s sharpening and maintenance instructions for the saw chain.

7.Only use replacement bars and chains specified by the manufacturer or the equivalent.

NOTE: Low-kickback saw chain is chain that has met the kickback performance requirements of ANSI B175.1-2000 (American National Standard for Power Tools Gasoline- Powered Chain Saws Safety Requirements) when tested on the representative sample of chain saws below 3.8 c.i.d. specified in ANSI B175.1-2000.

2-2. OTHER SAFETY PRECAUTIONS

1.DO NOT operate a chain saw with one hand! Serious injury to the operator, helpers, bystanders, or any combination of these persons may result from one- handed operation. A chain saw is intended for two- handed use.

2.DO NOT operate a chain saw when you are fatigued.

3.Use safety footwear, snug-fitting clothing, protective gloves, and eye, hearing and head protection devices.

4.Use caution when handling fuel. Move the chain saw at least 9.1m (30 feet) from the fueling point before starting the engine.

5.DO NOT allow other persons to be near when starting or cutting with the chain saw. Keep bystanders and animals out of the work area.

6.DO NOT start cutting until you have a clear work area, secure footing, and a planned retreat path from the falling tree.

7.Keep all parts of your body away from the saw chain when the engine is running.

8.Before you start the engine, make sure that the saw chain is not contacting anything.

9.Carry the chain saw with the engine stopped, the guide bar and saw chain to the rear, and the muffler away from your body.

10.DO NOT operate a chain saw that is damaged, improperly adjusted, or not completely and securely assembled. Be sure that the saw chain stops moving when the throttle control trigger is released.

11.Shut off the engine before setting the chain saw down.

12.Use extreme caution when cutting small size brush and saplings because slender material may catch the saw chain and be whipped toward you or pull you off balance.

13.When cutting a limb that is under tension, be alert for springback so that you will not be struck when the ten- sion in the wood fibers is released.

14.Keep the handles dry, clean, and free of oil or fuel mix- ture.

15.Operate the chain saw only in well-ventilated areas.

16.DO NOT operate a chain saw in a tree unless you have been specifically trained to do so.

17.All chain saw service, other than the items listed in the user manual safety and maintenance instructions, should be performed by competent chain saw service personnel.

18.When transporting your chain saw, use the appropri- ate guide bar scabbard.

19.DO NOT operate your chain saw near or around flam- mable liquids or gases whether in or out of doors. An explosion and/or fire may result.

20.USE THE RIGHT TOOL: Cut wood only. Do not use the chain saw for purposes for which it was not intend- ed. For example, do not use the chain saw for cutting plastic, masonry, or non-building materials.

21.Do not attempt to add fuel or lubricating oil to saw while engine is running.
