SAFETY PRECAUTIONS FOR CHAIN SAW USERS

KICKBACK SAFETY PRECAUTIONS

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. Tip contact in some cases may cause a lightning-fast reverse reaction,

kicking the guide bar up and back toward the operator. Pinching the saw chain along the top of the guide bar

may push the guide bar rapidly back toward 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 that 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 the manufacturer's sharpening and maintenance instructions for the saw chain.

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

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 fatigue.

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 10 feet (3 m) from the fueling point before

starting the engine.

5. 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.

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 release.

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 tension in the wood fibers is released.

WARNING

— US-8 —

14. Keep the handles dry, clean, and free of oil or fuel mixture.

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 Owner's/Operator's Manual maintenance

instructions, should be performed by competent chain saw service personnel. (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 subsequently could cause the flywheel to

burst.).

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