RULES FOR SAFE OPERATION

A. Kickback Safety Precaution for Chain Saw Users

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.

Tip contact in some cases 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 .

The Kick Guard ® device is not installed on the guide bar when you purchase your ECHO chain saw. The Kick Guard ® can be used in a majority of cutting operations, and is especially recommended for beginners, homeowners, or chain saw novices.

Most cutting operations can be accomplished with the Kick Guard® in place.

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.

B. Other Safety Precautions

1. Do not operate a chain saw with one hand! Serious injury to the operator, helpers, byst anders, 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 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.

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

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

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 Instruction 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 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 S tandard J335b 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.

WARNING DANGER

• During operation, the muffler or catalytic muffler and surrounding cover become hot.

• Never suspend the saw on a lanyard with the engine running.

• Always use the saw from the right-hand side of your body – NEVER from the left side.

• Always wear proper safety clothing to protect your lower body from sharp saw chain and hot

muffler.

• Always keep exhaust area clear of flammable debris during transportation or when storing, otherwise serious property damage or personal injury may result.

W ARNING DANGER

Using improper replacement components or removing safety devices may result in serious or fatal injury .

3. Remove guide bar and saw chain if necessary.

NOTE: See “MAINTENANCE AND CARE” instructions for guide bar, sprocket, and saw chain maintenance.

4. Mount guide bar (G) on studs, and slide toward sprocket to make saw chain installation easier .

5. Install saw chain (H) as shown, with cutters on top of guide bar facing forward.

IMPORTANT

Be certain tensioner fits into lower adjuster hole (K) before tightening guide bar nuts.

NOTE

Move chain brake lever fully rearward to install sprocket guard to saw.

6. Install sprocket guard (J), and tighten guide bar nuts (I) finger tight.

ADJUSTMENT, CHAIN TENSION

FUEL AND LUBRICANT

NOTICE: Use of unmixed, improperly mixed, or fuel older

than 90 days, (stale fuel), may cause hard starting, poor performance, or severe engine damage and void the product warranty. Read and follow instructions in the Storage section of this manual.

FUEL STATEMENT

GASOLINE - Use 89 Octane [R+M/2] (mid grade or higher)

gasoline or gasohol known to be good quality. Gasohol may contain up to 10% Ethyl (grain) alcohol or 15% MTBE (methyl tertiary-butyl ether). Gasohol containing methyl (wood) alcohol is NOT approved.

Two Stroke Oil - A two-stroke engine oil meeting ISO-L-EGD (ISO/CD 13738) and J.A.S.O. FC Standards must be used. Echo brand premium Power Blend TM Universal 2Stroke Oil meets these standards. Engine problems due to inadequate lubrication caused by failure to use an ISO-L-EGD and J.A.S.O. FC certified oil, such as Echo premium Power BlendTM, will void the two-stroke engine warranty. (Emission related parts only are covered for two years, regardless of two-stroke oil used, per the statement listed in the Emission Defect Warranty Explanation.)
