B. 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 and protective gloves.

Wear eye, hearing, and head protection devices.

4.Use caution when handling fuel. Move the chain saw at least 3 m (10 feet) 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. When carrying a chain saw with the engine running, push the front hand guard forward to engage the chain brake.

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 spring-back so that you will not be struck when the tension in the wood fibers is released.

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 items listed in the Instruction manual maintenance instructions, should be performed by competent 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 could subsequently cause the flywheel to burst.)

18.When transporting your chain saw, use

the appropriate guide bar scabbard.

19.Spark arrestor mufflers approved to SAE Standard J335 are standard on ECHO chain saws to reduce the possibility of forest fires.

Do not operate the chain saw with a loose or defective muffler.

Do not remove the spark arrestor screen.
