RULES FOR SAFE OPERATION
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.
1.With a basic understanding of kickback,
you can reduce or eliminate the
element of surprise.
Sudden surprise contributes to
accidents.
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.
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.
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.
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.
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.
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.

CS-355T
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 onehanded operation.
A chain saw is intended for two-handed
use.
11.Shut off the engine before setting the
chain saw down.
2.Do not operate a chain saw when you
are fatigued.
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.
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.
3.Use safety footwear, snug-fitting
clothing and protective gloves.
Wear eye, hearing, and head protection
devices.
14.Keep the handles dry, clean, and free
of oil or fuel mixture.
4.Use caution when handling fuel.
Move the chain saw at least 3 m (10
feet) from the fueling point before
starting the engine.
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.
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.
17.All chain saw service, other than
items listed in the Operator's 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.)
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.
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.
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.

OPERATOR SAFETY
VIBRATION AND COLD
EYE AND HEARING PROTECTION
• It is believed that a condition called Raynaud’s
Phenomenon, which affects the fingers of certain
individuals, 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 fingers.
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 fill 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 fingers, followed by whitening
and loss of feeling, consult your physician before
further exposing yourself to cold and vibration.
• Wear eye protection goggles that meet ANSI
Z 87.1 requirements.
Goggles meeting the requirements 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 fitting durable clothing should be worn.
Pants should have long legs, do not wear shorts.
Do not wear loose fitting clothing, scarves,
neckties, 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.
REPETITIVE STRESS INJURY
HOT HUMID WEATHER
• It is believed that over-using the muscles and
tendons of the finger, 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.
• Heavy protective clothing can increase operator
fatigue 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 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.
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
repetitive movement.
• Do exercises to strengthen hand and arm
muscles.
• See a doctor if you feel tingling, numbness or
pain in your fingers, hands, wrists or arms.
The sooner RSI/CTS is diagnosed, the more
likely permanent nerve and muscle damage can
be prevented.
CS-355T

SPARK ARRESTOR MUFFLER
• The spark arrestor muffler controls the exhaust
noise and prevents hot, glowing particles of
carbon from leaving the muffler.
Make sure the spark arrestor screen is in good
repair and properly seated in the muffler.
• 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 certified per USDA Forest Service
Regulation SAE J335.
Check with your local or state authorities for
specific regulations in your area.
Failure to follow these requirements is a violation
of the law.
CORRECT USE OF CHAIN BRAKE
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.
Rotational kickback
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.
This model needs to use low-kickback chain and
bar.
Do not use a combination other than those
specified on page 23.
For your own safety, do not remove the chain
brake system.

CS-355T
CUTTING INSTRUCTION
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 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.
Kickback
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.
Some material may adversely affect the housings
of your chain saw.
(Example palm Tree Acid, fertilizer etc.)
To avoid housing deterioration, carefully remove all
packed sawdust around clutch and guide bar area
and wash with water. Coat metal parts with light oil.
CS-355T

FELLING THE TREE
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 3 m (10 feet) from the trunk to avoid
the trunk kicking back over the stump.
3 m (10 feet)
Retreat
Direction of fall
45°
45°
Retreat
Not this way
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 opposite 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.

CS-355T
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
vertically 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
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.
Uphill position
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.
Finish cut
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.
First cut
Board or flat stones
DANGER
• 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 in this Manual and Safety Manual.
CS-355T
20
CHAIN BRAKE OPERATION
Kickback motion
• Set the lever in the unlocked position before
starting to cut.
• If the brake is tripped by kickback 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 locked.
Improper thrust cutting
Kickback motion
When the bar nose hits another tree, etc.
TESTING THE BRAKE
Chain brake function
When the lever is pushed forward, chain brake
instantly stops the chain.
• 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.
WARNING
If the chain does not stop immediately, return
the saw to your authorized ECHO dealer for
repair.
Chain brake unlock
When the lever is fully pulled toward the
operator, brake is unlocked.
NOTICE
• For practice, while cutting a small tree, push
the lever forward to lock the brake.
• Confirm that the brake works properly before
each use.
• If the chain brake is clogged with wood chips,
function of the brake may deteriorate.
Always keep the device clean.
• Do not increase engine revolution while the
chain brake is locked.
• Use the chain brake only in starting or in
emergencies.
• When using throttle latch at starting, keep the
chain brake locked.
And after starting the engine, unlock the brake
immediately.
IMPORTANT
Do not allow the saw to tip forward in order to
avoid damage to the chain.
21
CS-355T
AUTOMATIC CHAIN BRAKE
End of the guide bar may be placed at the
height of about 55 cm (22 in.).
Kickback produced from the tip of the guide bar will
trip the automatic chain brake. To make sure that
the automatic chain brake operates properly, follow
these steps:
1. Stop the engine.
2. Hold the saw with the guide bar approximately
55 cm (22 in.) above a wooden surface. Right
hand should hold the rear handle, and left hand
should hold the front handle.
3. Release the front handle and drop the end of the
guide bar against the wooden surface.
4. The impact should lock the chain brake.
55 cm
(22 in.)
IMPORTANT
When checking the operation of the automatic
chain brake, use a soft surface substance like
wood to provide the impact so the chain is not
damaged.
Rear handle should be gripped lightly with the
right hand.
