PERSONAL EQUIPMENT
•Always wear approved goggles to protect your eyes.
Wood chips, dust, snapping branches and other debris
can be thrown by the cutting chain into the operator’s
facial area.
Goggles may also offer limited protection in the event
of the cutting chain hitting the operator in the eye area.
If conditions warrant that a ventilated face shield be
worn, goggles must be worn underneath it.
•ECHO recommends wearing hearing protection at all
times.
If not followed, hearing loss can occur.
You should reduce the risk of hearing damage by
wearing either “headset” type protectors or ear plugs
which are approved by an authorized organization.

CAUTION
Stuffing ears with cotton is not recommended.
•All persons who make part of their living using chain
saws should be tested periodically for hearing
deterioration.
•Always wear a cap or hat when working with a chain
saw. A safety hard hat is highly recommended when
felling or working under trees, or when objects can fall
on you.
•Wear heavy duty, non-slip gloves for improved grip,
and also for protection against cold and vibration.
•Safety tip shoes or boots with non-slip sole should be
worn.
Loose clothing or open jacket
•Never wear loose clothing, unbuttoned jackets, flared
sleeves and cuffs, scarves, tie-strings, neckties, cords,
chains, jewelry, etc. which could snag the saw chain or
underbrush.
•Clothing should be of sturdy, protective material. It
should be snug-fitting to resist snagging, but roomy
enough for freedom of movement.
•Trouser legs should not be flared or cuffed, and should
be either tucked into the boot tops or trimmed short.
FUEL
WARNING DANGER
••
•PETROL AND FUEL ARE EXTREMELY
••
FLAMMABLE. IF SPILLED OR IGNITED BY
IGNITION SOURCE, IT CAN CAUSE FIRE AND
SERIOUS INJURY OR PROPER TY DAMAGE.
EXTREME CAUTION IS REQUIRED WHEN
HANDLING PETROL OR FUEL.
••
•AFTER REFUELLING, TIGHTEN FUEL CAP

•The fuel tank may be under pressure. Always loosen
the fuel cap and wait for pressure to be equalized
before removing the cap.
•Fill the fuel tank outdoors over bare ground and install
the fuel cap securely. Do not pour fuel indoors.
•Wipe any spilled fuel off the unit.
•Never refuel while the engine is still hot, or fuel a
running engine.
•Do not store the unit with fuel in its tank, because a
fuel leak could start a fire.
•Bring an extinguisher or shovel in case of fire.
Despite the precautions which can be taken, operating
a chain saw, or just working in the forest, presents
dangers.

STARTING ENGINE
•Move the chain saw at least 3 m from the fuelling point
before starting the engine.
•Do not allow other persons to be near the chain saw
when you are starting or cutting with the chain saw.
Keep bystanders and animals out of the work area.
Do not let anyone hold wood for you to cut.
•Do not start cutting until you have a clear work area,
secure footing and a planned retreat path from the
falling tree.
•Before you start the engine, make sure that the saw
chain is not contacting anything.
•Keep the handles dry, clean, and free of oil or fuel
mixture.
•Operate the chain saw only in well-ventilated areas.
Exhaust gas, oil mist (from chain saw lubrication) or
saw dust saw is harmful to health.
Rotational kickback
TRANSPORTATION
•When transporting your chain saw, use the appropriate
guide bar cover.
•Carry the chain saw with the engine stopped, the guide
bar and saw chain to the rear, and the silencer away
from your body.

2. KICKBA CK SAFETY PRECAUTIONS
WARNING 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.
•In some cases, tip contact may cause a lightning-fast
reverse reaction, kicking the guide bar up and back
toward the operator (this is called a rotational
kickback).
Pinching the saw chain along the top of the guide bar
may push the guide bar rapidly back toward the
operator (this is called a linear kickback).
Linear kickback
•Either or these reactions may cause you to lose control
of the saw and come in contact with the moving chain,
which could result in serious personal injury. As a
chain saw user, you should take several steps to keep
your cutting jobs free from accident or injury.
•With a basic understanding of kickback, you can
reduce or eliminate the element of surprise.
Sudden surprise contributes to accidents. Understand
that rotational kickback is preventable by keeping an
unshielded bar nose from touching an object or the
ground.
CS-1201

Don’t reach far out
•Do not operate a chain saw with one hand!
Serious injury to the operator, helpers or bystanders
may result from one-handed operation. For proper
control, always use two hands when operating a chain
saw, one of which operates the trigger. Otherwise, this
can result in the chain saw “skating” or skidding, which
can result in personal injury due to loss of control.
•Keep a good firm grip on the saw which both hands,
with 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 enriching the chain
saw handles. A firm grip will help you reduce kickback
and maintain control of the saw. Two hands must be
used to control the saw at all times.
•Do not overreach or cut above chest height.
•Make sure that the area in which you are cutting is free
from obstructions. Do not let the bar nose contact a
log, branch, or any other obstruction which could be hit
while you are operating the saw.
•Cutting at high engine speeds may reduce the
likelihood of kickback. But cutting at part-throttle or low
engine speeds may be preferable to control the chain
saw in tight situations and may also reduce the
likelihood of kickback.
•Follow manufacturer’s sharpening and maintenance
instructions for the saw chain.
•Use only replacement guide bars and chains specified
by the manufacturer, or the acceptable equivalents of
these guide bars and chains.
3. OTHER SAFETY PRECAUTIONS
VIBRATION AND COLD
It is believed that a condition called Raynaud’s
Phenomenon, which affects the fingers of certain
individuals, may be brought about by exposure to cold
and vibration.
Accordingly, your ECHO chain saw has shock mounts
designed to reduce the intensity of vibration received
through the handles.
Exposure to cold and vibration may cause tingling and
burning followed by loss of color and numbness in the
fingers. We strongly recommend you take the following
precautions 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 chain saw operation. Try
to fill a part of each work day with jobs other than chain
sawing.
•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.
REPETITIVE STRESS INJURIES
It is believed that over-using the muscles and tendons of
the fingers, hands, arms and shoulders may cause
soreness, swelling, numbness, weakness and extreme
pain to the areas just mentioned.
To reduce the risk of repetitive stress injury, do the
following:
•Avoid using your wrist in a bent, extended or twisted
position. Instead, try to maintain a straight wrist
position. Also, when grasping, use your whole hand,
not just the thumb and index finger.
•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 the hand and arm muscles.
•See a doctor if you feel tingling, numbness or pain in
the fingers, hands, wrists or arms.

CS-1201
MACHINE CONDITIONS
•Do not operate a chain saw that is damaged,
improperly adjusted, or not completely and securely
assembled.
Do not operate the chain saw with a loose or defective
silencer.
Be sure that the saw chain stops moving when the
throttle control trigger is released.
WARNING DANGER
DO NOT MODIFY A CHAIN SAW IN ANY WAY.
ONLY ATTACHMENTS AND PARTS SUPPLIED BY
KIORITZ CORP. OR EXPRESSLY APPROVED BY
KIORITZ CORP. FOR USE WITH THE SPECIFIC
KIORITZ CORP. CHAIN SAW MODELS ARE
AUTHORIZED.
ALTHOUGH CERTAIN UNAUTHORIZED
ATTACHMENTS ARE USEABLE WITH THE KIORITZ
CORP. POWERHEAD, THEIR USE MAY, IN FACT , BE
EXTREMELY DANGEROUS.
Know how limb
is stressed.
See page 12
SERVICES
•All chain saw service operations, other than items
listed in the operator’s manual maintenance
instructions, should be performed by competent
service personnel.
(For example, if an improper tool is used to hold the
flywheel in order to remove the clutch, structural
damage to the flywheel could occur and subsequently
could cause the flywheel to burst.)
Cutting from ladders is dangerous.
CUTTING
•Do not operate a chain saw in a tree unless you have
been specifically trained to do so.
•Keep all parts of your body away from the saw chain
when the engine is running.
•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.
•When cutting a limb that is under tension, be alert for
spring-back so that you will not be struck by the limb or
chain saw when the tension in the wood fibers is
released.
Cut only wood or wood products
WOOD PRACTICES
•Operating a chain saw safely requires a chain saw in
proper working order, sound judgement, and
knowledge of the methods which should be applied in
each cutting situation.
•Do not let any person use your saw unless he has
read this operator’s manual and fully understands its
instructions.
•Never let children operate the saw.
•Use your saw only to cut wood or wood products. Do
not cut solid metal, sheet metal, plastics or any nonwood materials.
•Cutting while on a ladder is extremely dangerous
because the ladder can slip and your control of the
chain saw is limited.
Working aloft should be left to professionals.
•Stop the engine before setting the chain saw down.
Stay on the uphill side of logs
Down
Keep both feet on the ground
•Stay on the uphill side when bucking or limbing logs
which might roll when cut.
•Keep both feet on the ground. Do not work from offthe-ground positions.

CAUTION
Whenever opening up the fuel tank, always loosen
the cap very slowly and wait for the tank pressure
to be equalized before removing the cap.
CS-1201
CHAIN LUBRICANT
Proper lubrication of the chain while in operation
reduces the friction between the chain and the guide bar
to a minimum and assures a longer life time. Use only
special chain oil of high quality for this purpose.
Do not use any waste or reclaimed oil to avoid various
problems with the oil pump.
In case of emergency, it is allowed to use motor oil for a
short time.

PRE CUTTING TEST
•Familiarize yourself with your chain saw before you
start actual cutting.
•For this purpose it may be wise to practice by cutting
some small logs or limbs several times.
•Do not allow either people or animals into the work
area. Multiple operators - Keep a safe distance
between two or more operators when working together
simultaneously.
CHAIN LUBRICATION TEST
Hold the chain just above a dry surface and open the
throttle to half speed for 30 seconds.
A thin line of “thrown” oil should be seen on the dry
surface.
CHECKING CHAIN TENSION
•Chain tension should be checked frequently during
work and corrected if necessary.
•Tension the chain as tight as possible, but so it can still
be pulled easily along the bar by hand.
WARNING DANGER
MAKE SURE THAT THE ENGINE IS SHUT OFF
WHEN CHECKING CHAIN TENSION.
Make felling cuts from
left side when possible
Kickback arc is away from you
CUTTING INSTRUCTION
GENERAL
In all circumstances the operation of the chain saw is a
one-man job.
It is difficult at times to take care of 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 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.
Be thoroughly familiar with the controls and the
responses of the saw.
Too short a distance to your body
If a felling cut must be made
from the right side, stay out of
the kickback path.
Do not crowed the saw with
your body!
Start the engine, see that is running properly. Squeeze
the trigger to open the throttle wide open, then start the
cut. It is not necessary to press down hard to make the
saw cut. If the chain is properly sharpened, the cutting
should be relatively effortless.
Pushing the saw too hard will slow the engine and
cutting will actually be more difficult.
Some material may adversely affect the housing of your
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.
WARNING DANGER
DO NOT LET THE NOSE OR TIP OF THE GUIDE BAR
TOUCH ANYTHING WHILE ENGINE IS RUNNING TO
AVOID KICKBACK.

FELLING A 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 from the trunk to avoid the trunk kicking back
over the stump. (See figure right, top)
Begin the cut on the side to which the tree is to fall.
Cut a notch approximately 1/3 of the way into the tree.
(See figure A)
The position of this notch is important since the tree will
try to fall “into” the notch. (See figure A)
The felling cut is made on the side opposite the notch.
Make the felling cut by placing spiked bumper 2.5 cm to
5 cm above the bottom of the notch and stop cutting at
approximately 1/10 of diameter to the inner edge of the
notch (See figure B) in order to leave the uncut portion
of the wood as a hinge.
Do not try to cut through to the notch with the felling cut.
The remaining wood between the notch cut and felling
cut will act as a hinge when the tree falls, guiding it in
the desired direction.
When the tree starts to fall, stop 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 with the spiked
bumper engaged, 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. (See figure C)

LIMBING
Limbing a fallen tree is much the same as bucking.
Never remove a limb from a tree while it is supporting
your weight.
Be careful of the tip touching other limbs.
Always use both hands.
Don’t cut with the saw overhead or the bar in a vertical
position. If the saw should kickback, you may not have
good enough control to prevent possible injury.
CAUTION
Don’t saw above chest height.
Do not cut above chest height
Know how limb is stressed
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.
CAUTION
Stay on the uphill side of logs.
Leave supporting limbs till last
Slide support logs under trunk
No standing on log
Stay on the uphill side of logs
CS-1201

TENSION AND COMPRESSION IN TIMBER
A length of timber lying on the ground will be subject to
tension and compression, depending at which points the
major support is.
When timber is supported at its ends the compression
side is at the top and the tension side is at the bottom.
To cut between these support points, make the first cut
downwards approximately 1/3rd the timber diameter.
The second cut is made upwards and should meet the
first cut.
When the timber is supported at one end only, make the
first cut upwards approximately 1/3rd the timber
diameter. The second cut is made downwards and
should meet the first cut.
CAUTION
If you have misjudged the effects of tension and
compression, and cut from the wrong side, the
timber will pinch the guide bar and chain, trapping it.
Racing the engine with the chain jammed will burn
out your clutch.
If the chain should become jammed and the saw
can not be removed from the cut do not force it out.
Stop the saw, force a wedge into the cut to open it
up.
Never force the saw when it is jammed.
Do not force the saw into the cut.
A dull chain is unsafe and will cause excessive
wear to the cutting attachments.
A good way to tell when the chain is dull is when
fine saw dust comes out instead of chips.

SAW CHAIN MAINTENANCE
Never operate a chain saw with a dull or damaged
chain. If the chain requires excessive pressure to cut or
produces dust instead of wood chips then inspect the
cutters for damage. When sharpening the chain the
objective will be to maintain the same angles and
profiles throughout its life as when it was new.
Inspect the chain for damage or wear every time you
refuel your chain saw.
When the length of the cutting teeth has worn down to
only 4 mm the chain must be replaced.

•Sharpening
In order to file the chain correctly you need:round file
and file holder (A), flat file (B) and a depth gauge tool
(C).
By using the correct file size (5.6 mm Round file) and a
file holder, it is easier to receive a good result.
Consult your ECHO dealer for correct sharpening tools
and sizes.

1. Lock the chain - push hand guard forward.
To rotate the chain - pull hand guard against front
handle.
2. Your chain will have alternative left and right hand
cutters. Always sharpen from the inside out.
3. Keep the angle lines of the file holder parallel to the
line of the chain and file the cutter back until the
damaged area (side plate and top plate) has been
removed.
4. Hold the file tipped 10° upward.
5. Sharpen the most damaged cutter first and then take
all the other cutters back to the same length.

1. The depth control determines the thickness of wood
chip produced and must be maintained correctly
throughout the chain life.
2. As the cutter length is reduced, the depth control
height is altered and must be reduced.
3. Position the depth gauge, and file off any of the depth
control which protrudes.
4. Round off the front of the depth control to allow
smooth cutting.

•Drive link serves to remove sawdust from the groove of
the guide bar. Therefore, keep the lower edge of the
drive link sharp, indicated as 5.
- When setting of the chain is finished, soak it in oil and
wash away filings completely before using.
- When the chain has been filed on the bar, supply
sufficient oil to it, and rotate the chain slowly to wash
away the filings before using again.
- If the chain saw is operated with filings clogged in the
groove, the saw chain and the guide bar will be
damaged prematurely.
- If the saw chain becomes soiled with resin for
instance, clean it with kerosene and soak it in oil.
