Rules For Safe Operation
Kickback Safety Precautions for Chain Saw Users
For more information
scan this QR code.
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.
Rotational kickback
The tip guard device is not installed on the guide bar when you
purchase your ECHO chain saw. The tip 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 tip guard in place.
Rotational kickback
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.
Chain moving downward at impact
Kickback Danger Zone
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.
Linear kickback
Pinch
4. Cut at high engine speeds.
5. Do not overreach or cut above shoulder height.
Kickback
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.

SAFETY
Correct Use Of Chain Brake
CHAIN BRAKE OPERATION
Locked
• 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.
TESTING THE BRAKE
Unlocked
• 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.
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.
Note:
• 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 RPM's while the chain brake is locked.
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: ANSI Standard B175.1 Safety Requirement for chain saws
ANSI Standard B175.1 stipulates that the brake shall stop the chain 0.12 seconds at an engine speed
of 13,500 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 here in order to ensure
that the brake performance is maintained in compliance with the Standard B175.1.

SAFETY
CS-355T
AUTOMATIC CHAIN BRAKE
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.
55 cm
(22 in.)
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.
When checking the operation of the automatic chain brake, use
a soft surface substance like wood to absorb the impact so the
chain is not damaged.
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 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.
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 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.

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

SAFETY
The ignition components of this machine generate an electromagnetic field during operation which
may interfere with some pacemakers. To reduce the risk of serious or fatal injury, persons with
pacemakers should consult with their physician and the pacemaker manufacturer before operating
this machine. In the absence of such information, ECHO does not recommend the use of ECHO
products by anyone who has a pacemaker.
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 vibration and cold. Exposure to vibration
and cold may cause tingling and burning sensations, 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, neck, feet, ankles,
hands, and wrists.
• Maintain good blood circulation by performing vigorous arm exercises during frequent work breaks, and
also by not smoking.
• Limit the hours of operation. Try to fill each day with jobs where operating the unit 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.
Repetitive Stress Injuries
It is believed that overusing the muscles and tendons of the
fingers, hands, arms, and shoulders may cause soreness,
swelling, numbness, weakness, and extreme pain in those
areas. 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. 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 with which you do the repetitive movement.
• Do exercise to strengthen the hand and arm muscles.
• Immediately stop using all power equipment and consult a doctor if you feel tingling, numbness, or pain in
the fingers, hands, wrists, or arms. The sooner RSI/CTS is diagnosed, the more likely permanent nerve
and muscle damage can be prevented.

OPERATION
Fuel
Alternative fuels, such as E-15 (15% ethanol), E-85 (85% ethanol) or any fuels not meeting ECHO
requirements are NOT approved for use in ECHO 2-stroke gasoline engines. Use of alternative fuels
may cause performance problems, loss of power, overheating, fuel vapor lock, and unintended
machine operation, including, but not limited to, improper clutch engagement. Alternative fuels may
also cause premature deterioration of fuel lines, gaskets, carburetors and other engine components.
Fuel Requirements
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. ECHO brand Power Fuel™ is 93 octane, ethanol-free fuel
premixed with ECHO Red Armor® engine oil at 50:1 ratio. Use of ECHO Power Fuel™ is recommended to
extend engine life in all air-cooled 2-stroke and 2/4-stroke hybrid engines.
Two Stroke Oil - A two-stroke engine oil meeting ISO-L-EGD (ISO/CD 13738) and J.A.S.O. FD Standards
must be used. Echo brand premium Power Blend X™ 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. FD certified oil, such as Echo premium Power Blend X™, will void the two-stroke engine warranty.
Echo premium Power Blend X™ 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.

General
• This chain saw is designed for cutting wood or wood
products. Do not cut solid metal, sheet metal, plastic or
any non-wood materials.
• 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.

CS-355T
OPERATION
• 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!
Kickback
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.
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.

Felling the Tree
For more information on
scan this QR code.
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!
3 m (10 feet)
Direction of fall
Retreat
45°
45°
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.
Not this way
Retreat
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.
Direction of fall
Hinge
5 cm (2 in.)
First cut
Felling cut
Notch
Second cut
5 cm (2 in.)
One-third tree diameter
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
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.

OPERATION
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.
Uphill position
• 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.
Finish cut
First cut
Support
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.
When the bar nose hits another tree, etc.

Engine Break-In
New engines must be operated a minimum duration of two
tanks of fuel break-in before carburetor adjustments can be
made. During the break-in period your engine performance
will increase and exhaust emissions will stabilize. Idle speed can be adjusted as required.
High Altitude Operation
This engine has been factory adjusted to maintain satisfactory starting, emission, and durability
performance up to 1,100 feet above sea level (ASL) (96.0 kPa). To maintain proper engine operation and
emission compliance above 1,100 feet ASL the carburetor may need to be adjusted by an authorized ECHO
service dealer.
If the engine is adjusted for operation above 1,100 feet ASL, the carburetor must be re-adjusted when
operating the engine below 1,100 feet ASL, otherwise severe engine damage may result.
1. Before adjusting carburetor clean or replace air filter and muffler “Spark Arrestor Screen”.
2. Make sure the bar and chain are properly adjusted.
3. Start engine and run several minutes to bring to operating temperature. Flash choke twice during
warm-up to clear any air from the fuel system.
4. Stop engine. Turn “H” speed needle counterclockwise (CCW) to stop. Turn “L” speed needle midway
between full clockwise (CW) stop and CCW stop.
5. Idle Speed Adjustment:
• Start engine, turn “Idle” speed adjustment screw “T” CW until the saw chain begins to move, then turn
screw out CCW until the saw chain stops moving. Turn screw out, CCW, an additional 1/4 turn.
When carburetor adjustment is completed, the saw chain should not move at idle, otherwise
serious personal injury may result.
6. Accelerate to full throttle for 2 - 3 seconds to clear any excess fuel in the engine, then return to idle.
Accelerate engine to full throttle to check for smooth transition from idle to high speed. If engine hesitates
turn “L” needle CCW 1/8 turn and repeat acceleration. Continue adjustment until smooth acceleration
results.
7. Check idle speed and reset if necessary as described in item 5. If a tachometer is available idle speed
should be set to value listed on technical data page.
