1. Fatigue causes carelessness. Be more cautious before
rest periods and before the end of your shift.
2. Personal protective clothing required by your safety
organizations, government regulations, or your em-
ployer should be used; otherwise, sung tting clothing,
protective eyewear, safety footwear and hand, leg and
hearing protection should be worn.
Note: Personal protective clothing should meet
the requirements of applicable Standards.
3. Before fueling, servicing or transporting your chain saw
switch off the engine. To help prevent re, restart your
chain saw at least 3 m from the fueling area.
4. When using a chain saw a re extinguisher should be
available.
5. When felling, keep at least 2 tree lengths between your-
self and your fellow workers.
6. Plan your work; assure yourself of an obstacle-free
work area and, in the case of felling, of an escape path
from the falling tree.
7. Follow instructions in your operator’s manual for start-
ing the chain saw and control the chain saw with a rm
grip on both handles when it is in operation. Keep han-
dles dry, clean and free of oil. A chain saw should never
be carried with the engine running.
8. When transporting your chain saw, use the appropriate
transportation covers that should be available for the
guide bar and saw chain.
9. Never operate a chain saw that is damaged, improperly
adjusted, or is not completely and securely assem-
bled. Be sure that the saw chain stops moving when
the throttle control trigger is released. Never adjust the
guide bar or saw chain when the engine operating.
10. Beware of carbon monoxide poisoning. Operate the
chain saw in well-ventilated areas only.
11. Do not attempt a pruning or liming operation in a stand-
ing tree unless specically trained to do so.
12. Guard against kickback. Kickback is the upward
motion of the guide bar, which occurs when the saw
chain, at the nose of the guide bar, contact an object.
Kickback can lead to dangerous loss of the chain
saw.
TO AVOID KICKBACK:
(a) Contact of the guide bar tip with any object should
be avoided.
(b) Tip contact may cause the guide bar to move
suddenly upward and backward which may cause
serious injury.
(c) Always use two hands when operating the chain
saw.
(d) Use a rm grip, thumbs and ngers encircling the
handles.
(e) Don’t overreach.
(f) Avoid cutting above shoulder height.
(g) Follow the manufacture’s instructions for sharpen-
ing and maintenance of the saw chain.
13. When boring with the chain saw, the initial cut should
be introduced with the lower part of the nose (tip) until
the hole is sufciently large so as to introduce the entire
nose (tip) of the guide bar. This technique should re-
duce the danger of kickback.
RULES FOR SAFE OPERATION
14. A chain saw is intended for two-handed use.
Serious injury to the operator, helpers and/or by-
standers may result from one-handed operation.
CAUTION
A. Allow your chain saw to cool before refueling,
and do not smoke while refueling.
B. Do not allow other persons or animals close to
running chain saw or close to where a tree is be-
ing felled.
C. Use extreme caution when cutting small size
brush and saplings because slender material
may catch the saw chain and be whipped toward
you.
D. When cutting a limb that is under tension be alert
for spring-back.

instantly stops the chain.
Chain brake unlock
When the lever is fully pulled, toward the
operator, brake is unlocked.
CHAIN BRAKE OPERATION
• 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 pos-
sible damage to the engine or clutch.
• Do not attempt to operate the engine with the brake
locked.
TESTING THE BRAKE
• Start the engine on a solid level surface and run at a
fast idle until warm.
• Hold the saw rmly by the handles and accelerate the
engine to a fast idle.
• Slowly operate the chain brake lever while holding the
saw rmly on the ground. When the brake lever trips,
the chain should stop. Immediately release the throttle
trigger.
IMPORTANT
Do not allow the saw to tip forward in order to avoid
damage to the chain.
WARNING
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.
• Conrm that the brake works properly before each
use.
• If the chain brake is clogged with wood chips, func-
tion of the brake may deteriorate. Always keep the
device clean.
• Do not increase engine RPM's while the chain
brake is locked.
coRRect Use oF cHAIn BRAKe
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 fol-
lows.
USA : ANSI Standard B175.1

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
Using improper replacement components or removing safety devices may result in serious or fatal injury.
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
The ignition components of this machine generate an electromagnetic eld 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 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 CSA
Z 94.3 requirements. Goggles meeting the require-
ments have the mark “Z 94” 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, 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.
• 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.

CHAIN LUBRICANT
Proper lubrication of the chain while in operation reduces fric-
tion 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 rell chain oil.
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 con-
tainer. Store in a well-ventilated, unoccupied building,
away from sparks and ames.
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.

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 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 us-
ing 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 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 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.
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!

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 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 op-
posite 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 rst cut, very carefully so as not to cause kickback.
The nal 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.

Don’t cut with the saw overhead or the bar in a vertical po-
sition. 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 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.
