RULES FOR SAFE OPERATION

A. Kickback Safety Precautions for Chain Saw Users

B. Other Safety Precautions

1. Do not operate a chain saw with one hand!

Serious injury to the operator, helpers, by-

standers, or any combination of these per-

sons 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; pro-

tective gloves; and eye, hearing and head pro-

tection devices. Keep long hair away from

engine and air intake. Retain hair with cap or

net.

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.

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. Ei-

ther 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 recom-

mended for beginners, homeowners, or chain saw

novices. Most cutting operations can be accom-

plished 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 sur-

prise. Sudden surprise contributes to acci-

dents.

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 cut-

ting 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 main-

tenance instructions for the saw chain.

7. Only use replacement bars and chains, or the

equivalent, specified by the manufacturer.

WARNING

•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

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

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 to-

ward 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 compe-

tent chain saw service personnel. (For ex-

ample, 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 Stan-

dard 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

Check fuel system for leaks due to fuel tank damage, especially if the unit is dropped. If damage or leaks are

found, do not use unit, otherwise serious personal injury or property damage may occur. Have unit repaired by an

authorized servicing dealer before using.

Gasoline - Use 89 Octane [R+M/2] (mid grade or higher) gasoline known to be good quality. Gasoline may contain up

to 10% Ethanol (grain alcohol) or 15% MTBE (methyl tertiary-butyl ether). Gasoline containing methanol (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/FD Standards must be

used. Echo brand premium Power Blend X TM Universal 2-Stroke Oil meets these standards. Engine problems due to

inadequate lubrication caused by failure to use an ISO-L-EGD (ISO/CD 13738) and J.A.S.O. FC/FD certified oil, such

as Echo premium Power Blend X TM, will void the two-stroke engine warranty.

IMPORTANT

Echo premium Power Blend X 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

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 RUNNING!

• 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.

• Inspect for fuel leakage. If fuel leakage is found, do not start or operate unit until leakage is repaired.

• Move at least 3m (10 ft.) from refueling location before starting the engine.

Mixing Instructions

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 well-

ventilated, 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.

OPERATION

IMPORTANT

This saw features a combination ignition/choke switch that automatically sets the throttle speed to fast idle for

quick starting. Do not squeeze trigger during cold starts until after unit has started, or fast idle and choke

settings will be released, and engine may not start.

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.

15

WARNING

Read the ECHO “CHAIN SAW SAFETY MANUAL” included

with your chain saw for additional cutting and safety instruc-

tions. Failure to obey all instructions may result in serious or

fatal injuries.

In all circumstances the operation of the chain saw is a one-

man 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 re-

sponses 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

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!

CUTTING INSTRUCTIONS

Kickback

GENERAL

16

WARNING

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.

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, cau-

tion is the word. Be careful of the tip touching other limbs.

Always use both hands.

LIMBING

17

Don’t cut with the saw overhead or the bar in a vertical posi-

tion. If the saw should kick back you may not have good

enough control to prevent possible injury.

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.

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.

WARNING

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.

MAINTENANCE AND CARE

WARNING

Moving parts can amputate fingers or cause severe injuries. Keep hands, clothing and loose objects away from

all openings. Always stop engine, disconnect spark plug, and make sure all moving parts have come to a com-

plete stop before removing obstructions, clearing debris, or servicing unit. Allow unit to cool before performing

service. Wear gloves to protect hands from sharp edges and hot surfaces.

Your ECHO unit is designed to provide many hours of trouble free service. Regular scheduled maintenance will help

your unit achieve that goal. If you are unsure or are not equipped with the necessary tools, you may want to take your

unit to an ECHO Service Dealer for maintenance. To help you decide whether you want to DO-IT-YOURSELF or have

the ECHO Dealer do it, each maintenance task has been graded. If the task is not listed see your Echo dealer for

repairs.
