7. Keep all parts of your body away from the saw
chain when the engine is running.
14.Keep the handles dry, clean, and free of oil or
fuel mixture.
8. Before you start the engine, make sure that
the saw chain is not contacting anything.
15.Operate the chain saw only in well-ventilated
areas.
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.
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 the items listed
in the Instruction Manual maintenance instruc-
tions, should be performed by competent chain
saw service personnel. (For example, if im-
proper tools are used to remove the flywheel
or if an improper tool is used to hold the fly-
wheel in order to remove the clutch, structural
damage to the flywheel could occur and could
subsequently cause the flywheel to burst.)
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 to-
ward you or pull you off balance.
18.When transporting your chain saw, use the
appropriate guide bar scabbard.
19.Spark arrestor mufflers approved to SAE Stan-
dard J335b 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 ar-
restor screen.
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.

Two Stroke Oil - A two-stroke engine oil meeting ISO-L-EGD
(ISO/CD 13738) and J.A.S.O. FC Standards must be used.
Echo brand premium Power Blend TM Universal 2-Stroke Oil
meets these standards. Engine problems due to inadequate
lubrication caused by failure to use an ISO-L-EGD and J.A.S.O.
FC certified oil, such as Echo premium Power BlendTM, will void
the two-stroke engine warranty. (Emission related parts only
are covered for two years, regardless of two-stroke oil used, per
the statement listed in the Emission Defect Warranty Explana-
tion.)
MixingInstructions
1. Fill an approved fuel container with half of the
requiredamountofgasoline.
2. Add the proper amount of 2-stroke oil to
gasoline.
3. Close container and shake to mix oil with
gasoline.
4. Add remaining gasoline, close fuel container,
and remix.
IMPORTANT
Echo premium Power BlendTM 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.
IMPORTANT
Spilled fuel is a leading cause of hydrocar-
bon emissions. Some states may require
the use of automatic fuel shut-off containers
to reduce fuel spillage.
Handling Fuel
After use
• DO NOT store a unit with fuel in its tank. Leaks
can occur. Return unused fuel to an approved
fuelstoragecontainer.
WARNING
DANGER
Fuel is VERY flammable. Use extreme care when mixing,
storing or handling or serious personal injury may result.
• Useanapprovedfuelcontainer.

CUTTING INSTRUCTIONS
WARNING
GENERAL
DANGER
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 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 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 difficult.
NOTE
Some material may adversely affect the housings of your
ECHO chain saw.
Kickback
(Example: Palm TreeAcid, 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
DANGER
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!

FELLING A TREE
DIRECTION
OFFALL
WARNING
DANGER
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
3m from the trunk to avoid the trunk kicking back over the
stump.
45°
Direction of fall
First cut
Hinge
2”
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.
Felling cut
2”
Notch
Second cut
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
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.
14
Download from Www.Somanuals.com. All Manuals Search And Download.
Don’t cut with the saw overhead or the bar in a vertical posi-
tion. 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.
Uphill position
When cutting on a slope or hillside, always stand uphill.
BUCKING
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.
FINISH CUT
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. 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
KICKBACK
WARNING
DANGER
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 back-
wards towards the operator.
•
Improper thrust cutting.
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 on page 2
and 3 of this manual.
•
When the bar nose hits another tree, etc.

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 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 B175.1-2000 Safety Requirement for chain saws
CSA Standard Z 62.1 CHAIN SAWS
Canada:
WARNING
DANGER
ANSI Standard B175.1-2000 stipulates that the brake shall stop the chain in 0.15 seconds maximum (.12 sec avg)
at full throttle. 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 to ensure that the brake performance is main-
tained in compliance with the Standard B175.1-2000.
Kickback Motion:
Function:
•
When the bar nose hits another tree, etc.
•
When the lever is pushed forward, chain brake
instantly works to stop the chain.
Release:
•
Improper thrust cutting.
•
When the lever is fully pulled toward the operator, brake is
released.

TESTING THE BRAKE
INSTALLATION
•
•
•
Start the engine on a solid level surface and run at a fast
idle until warm.
•
Echo recommends that the chain brake should be
serviced by an authorized Echo servicing dealer.
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.
OPERATION
•
Set the lever in the released position before starting to
cut.
IMPORTANT
Do not allow the saw to tip forward in order to avoid
damage to the chain.
•
If the brake is tripped by kick back 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
engaged.
If the chain does not stop, immediately return the saw to your
authorized Echo dealer for repair.
