A. Kickback Safety Precautions 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, or the equivalent, specified by the manufacturer.

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; protective gloves; and eye, hearing and head protection devices. Wear protective hair covering to contain long hair.

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.

2

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 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 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 Standard 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.

WARNING DANGER

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

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 2-Stroke 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 Blend TM , 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.)

IMPORTANT

Echo premium Power Blend TM Universal 2-Stroke Oil may be mixed at 50:1 ratio for application in all Echo engines sold in the past regardless of ratio specified in those manuals.

Handling Fuel

WARNING DANGER

Fuel is VERY flammable. Use extreme care when mixing, storing or handling or serious personal injury may result.

• Use an approved fuel container.

• DO NOT smoke near fuel.

• DO NOT allow flames or sparks near fuel.

• Fuel tanks/cans may be under pressure. Always loosen fuel caps slowly allowing pressure to equalize.

• NEVER refuel a unit when the engine is HOT or RUN-

NING!

• DO NOT fill fuel tanks indoors. ALWAYS fill fuel tanks outdoors over bare ground.

• DO NOT overfill fuel tank. Wipe up spills immediately.

• Securely tighten fuel tank cap and close fuel container after refueling.

1. Fill an approved fuel container with half of the required amount of gasoline.

2. Add the proper amount of 2-stroke oil to gasoline.

3. Close container and shake to mix oil with gasoline.

4. Add remaining gasoline, close fuel container, and remix.

IMPORTANT

Spilled fuel is a leading cause of hydrocarbon emissions. Some states may require the use of automatic fuel shut-off containers to reduce fuel spillage.

After use

• DO NOT store a unit with fuel in its tank. Leaks can occur. Return unused fuel to an approved fuel storage container.

Storage - Fuel storage laws vary by locality.

Contact your local government for the laws affecting your area. As a precaution, store fuel in an approved, airtight container. Store in a wellventilated, unoccupied building, away from sparks and flames.

IMPORTANT

Stored fuel ages. Do not mix more fuel than you expect to use in thirty (30) days, ninety

(90) days when a fuel stabilizer is added.

IMPORTANT

Stored two-stroke fuel may separate.

ALWAYS shake fuel container thoroughly before each use.

10

CHAIN LUBRICANT

Proper lubrication of the chain while in operation reduces friction between the chain and the guide bar to a minimum and assures a longer service life.

• use bar and chain oil of high quality for this purpose.

• Do not use used or reclaimed oil to avoid various oiler problems.

• Use ECHO bar and chain oil.

• When ECHO bar and chain oil is not available:

Use motor oil, etc.

• Use bar and chain oil of the following grades:

SAE NO. 30 ..... in summer

SAE NO. 10 ..... in winter or when cutting resinous trees.

• When refueling, also refill chain oil.

WARNING DANGER

Read the ECHO “CHAIN SAW SAFETY MANUAL” included with your chain saw for additional cutting and safety instructions. Failure to obey all instructions may result in serious or fatal injuries.

In all circumstances the operation of the chain saw is a oneman job. It is difficult at times to take care for your own safety, so don’t assume the responsibility for a helper as well. After you have learned the basic techniques of using the saw, your best aid will be your own good common sense...

The accepted way to hold the saw is to stand to the left of the saw with your left hand on the front handlebar and your right hand on the rear handle so you can operate the throttle trigger with your right index finger.

Before attempting to fell a tree, cut some small logs or limbs.

Become thoroughly familiar with the controls and the responses of the saw.

Start the engine, see that it is running properly. Squeeze the trigger to open the throttle wide open and start the cut. If the chain is properly sharpened, the cutting should be relatively effortless. It is not necessary to press down hard to make the saw cut. Pushing the saw too hard will slow the engine and cutting will actually be more difficult.

NOTE

Some material may adversely affect the housings of your

ECHO chain saw.

(Example: Palm Tree Acid, fertilizer, etc.) To avoid housing deterioration, carefully remove all packed saw dust around clutch and guide bar area and wash with water. Coat metal parts with light oil.

WARNING DANGER

Do not let the tip of the bar touch anything while the engine is running. At cutting speed the chain is moving at a high rate of speed. Should the tip contact a limb or log while the chain is moving, the tip will be pushed upward with considerable force.

This is known as kickback. Avoid it!

WARNING DANGER

A falling tree can seriously damage anything it may hit

- a car, a house, a fence, a power line, or another tree.

There are ways to make a tree fall where you want it, so first decide where that is!

Before cutting, clear the area around the tree. You will need good footing while working and you should be able to work the saw without hitting any obstacles. Next, select a path of retreat. When the tree begins to fall you should retreat away from the direction of fall at a 45 degree angle and at least

3m from the trunk to avoid the trunk kicking back over the stump.

Begin the cut on the side to which the tree is to fall. Cut a notch about 1/3 of the way into the tree as shown. The position of this notch is important since the tree will try to fall “into” the notch. The felling cut is made on the side opposite the notch and at a level about 2” above the bottom of the notch. Do not try to cut through to the notch with the felling cut. The remaining wood between the notch cut and felling cut (about 2”) will act as a hinge when the tree falls, guiding it in the desired direction. When the tree starts to fall, kill the engine, place the saw on the ground and make your retreat quickly.

LIMBING

To fell big trees with a diameter exceeding twice the bar length, start the notching cuts from one side and draw the saw through to the other side of the notch. Start the back cut on one side of the tree, pivoting the saw through to form the desired hinge on that side.

Then remove the saw for the second cut. Insert the saw in the first cut, very carefully so as not to cause kickback. The final cut is made by drawing the saw forward in the cut to reach the hinge.

Limbing a fallen tree is much the same as bucking. Never limb on the tree that you are standing. When limbing, caution is the word. Be careful of the tip touching other limbs.

Always use both hands.

14

Don’t cut with the saw overhead or the bar in a vertical position. If the saw should kick back you may not have good enough control to prevent possible injury.

Uphill position

Bucking is the sawing of a log or fallen tree into smaller pieces. There are a few basic rules which apply to all bucking operations.

Keep both hands on the handles at all times.

Support logs if possible.

When cutting on a slope or hillside, always stand uphill.

FINISH CUT

Board or flat stones

Keep in mind that the wood is heavy and that it will bend and pinch the saw if improperly supported.

The trunk will weaken at the point where you make the cut unless the tree is lying on perfectly flat ground or supported as shown.

If you make the cut with the tree on the ground, don’t let the saw’s chain dig into the earth; it is harmful for the saw, and you stand a good chance of being struck by flying debris. To cut the trunk, use the bucking and two-cut sequence shown.

The first cut should be no deeper than one-third the trunk diameter.

Improper thrust cutting.

• When the bar nose hits another tree, etc.

WARNING DANGER

15

KICKBACK IS DANGEROUS

Kickback is generated when the rotation of the chain is arrested for some reason. The most dangerous effect of this action occurs when the nose of the bar contacts another object, the chain is momentarily stopped and all the energy of the engine throws the bar upwards and backwards towards the operator.

The chain saw industry and government agencies have attempted to prescribe various safety devices, but the best protection is to avoid kickback.

Comply with the Safety Precautions as listed on page 2 and 3 of this manual.

RAKE

The installation of a chain brake may be mandatory by law or as stipulated by insurance regulations in your area of operation. You should inquire through local government offices, your employer or your local dealer to ensure that your chain saw conforms to the required safety standard. Echo chain brakes have been designed and tested to comply with international safety standards as follows.

USA:

Canada:

ANSI Standard B175.1-2000 Safety Requirement for chain saws

CSA Standard Z 62.1 CHAIN SAWS

WARNING DANGER

ANSI Standard B175.1-2000 stipulates that the brake shall stop the chain in 0.15 seconds maximum (.12 sec avg) at full throttle. It is the responsibility of the Owner/Operator to ensure that the brake is serviced, adjusted and tested strictly in accordance with the instructions as detailed herein in order to ensure that the brake performance is maintained in compliance with the Standard B175.1-2000.

Kickback Motion:

Function:

• When the bar nose hits another tree, etc.

• When the lever is pushed forward, chain brake instantly works to stop the chain.

Release:

• Improper thrust cutting.

25

• When the lever is fully pulled toward the operator, brake is released.

INSTALLATION

• Echo recommends that the chain brake should be serviced by an authorized Echo servicing dealer.

OPERATION

• Set the lever in the released position before starting to cut.

• If the brake is tripped by kick back reaction, the chain will stop. Immediately release the throttle to avoid possible damage to the engine or clutch.

• Do not attempt to operate the engine with the brake engaged.

TESTING THE BRAKE

• Start the engine on a solid level surface and run at a fast idle until warm.

• Hold the saw firmly by the handles and accelerate the engine to a fast idle.

• Slowly operate the chain brake lever while holding the saw firmly on the ground. When the brake lever trips, the chain should stop. Immediately release the throttle trigger.

IMPORTANT

Do not allow the saw to tip forward in order to avoid damage to the chain.

If the chain does not stop, immediately return the saw to your authorized Echo dealer for repair.
