RULES FOR SAFE OPERATION

A. Kickback Safety Precautions for Chain Saw Users

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 rm 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 rm grip with thumbs and ngers

encircling the chain saw handles.

A rm 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 specied

by the manufacturer or the equivalent.

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 con-

trol 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 begin-

ners, 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. 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-tting 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.

B. Other Safety Precautions

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

mufer 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.

3

CS-400

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 bers 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 specically 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 ywheel or if an improper tool is used to

hold the ywheel in order to remove the clutch,

structural damage to the ywheel could occur and

could subsequently cause the ywheel to burst.)

18. When transporting your chain saw, use the

appropriate guide bar scabbard.

19. Spark arrestor mufers approved to SAE Standard

J335 are standard on ECHO chain saws to reduce

the possibility of forest res.

Do not operate the chain saw with a loose or

defective mufer. Do not remove the spark

arrestor screen.

WARNING

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

WARNING

• During operation, the mufer or catalytic mufer 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 mufer.

• Always keep exhaust area clear of ammable debris during transportation or when storing,

otherwise serious property damage or personal injury may result.

WARNING

Moving parts can amputate ngers 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 complete stop

before removing obstructions, clearing debris, or servicing unit.

• DO NOT start or operate unit unless all guards and protective covers are properly assembled to unit.

• NEVER reach into any opening while the engine is running. Moving parts may not be visible through openings.

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.

VIBRATION AND COLD

• It is believed that a condition called Raynaud’s Phe-

nomenon, which affects the ngers of certain individu-

als, may be brought about by exposure to vibration and

cold. Exposure to vibration and cold may cause tingling

and burning followed by loss of color and numbness

in the ngers.The following precautions are strongly

recommended because the minimum exposure which

might trigger the ailment is unknown.

• Keep your body warm, especially the head and neck,

feet and ankles and hands and wrists.

• Maintain good blood circulation by performing vigorous

arm exercises during frequent work breaks and also by

not smoking.

• Limit the number of hours of operation. Try to ll each

day with jobs where operating the chain saw, or other

hand-held power equipment is not required.

• If you experience discomfort redness and swelling of

the ngers, followed by whitening and loss of feeling,

consult your physician before further exposing yourself

to cold and vibration.

REPETITIVE STRESS INJURY

• It is believed that over-using the muscles and tendons

of the nger, hands, arms and shoulders may cause

soreness, swelling, numbness, weakness and extreme

pain to the areas just mentioned.

Certain repetitive hand activities may put you at a

high risk for developing a repetitive stress injury (RSI).

• An extreme RSI condition is Carpal Tunnel Syndrome

(CTS) which could occur when your wrist swells and

squeezes a vital nerve that runs through the area.

Some believe that prolonged exposure to vibration

may contribute to CTS.CTS can cause severe pain for

months or even years.

To reduce the risk of RSI/CTS, do the following:

• Avoid using your wrist in a bent, extended or twisted

position.

• Take periodic breaks to minimize repetition and rest

your hands.

• Reduce the speed and force in which you do the repeti-

tive movement.

• Do exercises to strengthen hand and arm muscles.

• See a doctor if you feel tingling, numbness or pain in

your ngers, hands, wrists or arms. The sooner RSI/

CTS is diagnosed, the more likely permanent nerve and

muscle damage can be prevented.

EYE AND HEARING PROTECTION

• Wear eye protection goggles that meet ANSI

Z 87.1 requirements. Goggles meeting the require-

ments have the mark “Z 87” stamped on them.

• Wear hearing protection.

If this guideline is not followed, hearing loss can occur.

ECHO recommends wearing hearing protection

at all times.

WEAR PROPER CLOTHING

• Snug tting durable clothing should be worn.Pants

should have long legs, DO NOT WEAR SHORTS.

Do not wear loose tting clothing, scarves, neck-

ties, jewelry or any item that may become tangled in

surrounding growth or the chain saw itself.

• Wear shoes with non-skid soles. DO NOT wear open

toed shoes or operate unit barefooted.

• Wear no-slip, heavy duty work gloves to improve your

grip on the chain saw handles. The gloves also help

reduce the transmission of machine vibration to your

hands.

• Keep long hair away from engine and air intake. Retain

hair with cap or net.

HOT HUMID WEATHER

• Heavy protective clothing can increase operator fa-

tigue which may lead to heat stroke. Schedule heavy

work for early morning, or late afternoon hours when

temperatures are cooler.

AVOID HOT SURFACES

• During operation, the mufer or catalytic mufer 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 mufer.

• Always keep exhaust area clear of ammable debris

during transportation or when storing, otherwise seri-

ous property damage or personal injury may result.

OPERATOR SAFETY

CS-400

SPARK ARRESTOR MUFFLER

• The spark arrestor mufer controls the exhaust

noise and prevents hot, glowing particles of car-

bon from leaving the mufer.

Make sure the spark arrestor screen is in good

repair and properly seated in the mufer.

• Certain internal combustion engines operated on

forest, brush, and/or grass-covered areas in the

states of Washington, Oregon, Idaho, California,

Minnesota, New Jersey and Maine, are required

to be equipped with a spark arrestor.

This requirement also applies to all U.S. Forest

Service lands.

In some of these areas, the spark arrestor system

must be certied per USDA Forest Service Regula-

tion SAE J335.

Check with your local or state authorities for spe-

cic regulations in your area.

Failure to follow these requirements is a violation

of the law.

DANGER

Kickback safety precaution for chain saw

users: 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.

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 of-

ces, 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 : ANSI Standard B175.1 - 2000

Safety Requirement for chain saws

Canada : CSA Standard Z 62.1 CHAIN SAWS

WARNING

ANSI Standard B175. 1 - 2000 stipulates that

the brake shall stop the chain 0.12 seconds

at an engine speed of 13500 r/min.

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

CUTTING INSTRUCTION

Kickback

GENERAL

CAUTION

•ReadtheECHO“CHAINSAWSAFETYMANUAL”

included with your chain saw for additional

cutting and safety instructions.

•Wearsuitablehearingprotectionsuchas

earmuffs or earplugs to protect against

objectionable or uncomfortable loud noises.

•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!

In all circumstances the operation of the chain saw is a

one-man job.

It is difcult 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 nger.

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 cut-

ting 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 cut-

ting will actually be more difcult.

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.

FELLING THE TREE

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 rst 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-de-

gree angle and at least 3 m (10 feet) 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. 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 op-

posite the notch and at a level about 5 cm (2 in.) 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 5 cm (2 in.) 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 rst cut, very carefully so as not to cause kick-

back. The nal cut is made by drawing the saw forward

in the cut to reach the hinge.

LIMBING

Limbing a fallen tree is much the same as bucking.

Never stand on the tree that you are limbing.

When limbing, caution is the word.

Be careful of the tip touching other limbs.

Always use both hands.

Don’t cut with the saw overhead or aligned vertical-

ly with your body. If the saw should kickback, you

may not have enough control to prevent possible

injury.

BUCKING

Bucking is the sawing of a log or fallen tree into

smaller pieces.

There are a few basic rules which apply to all buck-

ing operations.

Keep both hands on the handles at all times. Sup-

port 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 at

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 ying debris.

To cut the trunk, use the bucking and two-cut

sequence shown.

The rst 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 agen-

cies have attempted to prescribe various safety

devices, but the best protection is to avoid kick-

back.

Comply with the Safety Precautions as listed in

this manual.
