RULES FOR SAFE OPERATION
A. Kickback Safety Precaution 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.
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 rapidly
back towards the operator. Either of these reac-
tions may cause you to lose control of the saw
which could result in serious personal injury.
Do not rely exclusively upon the safety devices
builtintoyoursaw.Asachainsawuser,you should
take several steps to keep your cutting jobs free
from accident or injury.
1. With a basic understanding of kickback, you
can reduce or eliminate the element of sur-
prise. Sudden surprise contributes to acci-
dents.
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. Dont’ let go.
3. Make sure that the area in which you are cut-
ting is free from obstructions. Do not let the
nose of th 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 orcutaboveshoulderheight.
6. Follow manufacturer’s sharpening and main-
tenance instructions for the saw chain.
7. Only use replacement bars and chains speci-
fied by the manufacturer or the equivalent.
B. Other Safety Precautions
1. Do not operate a chain saw with one hand!
Serious injury to the operator, helpers, by-
standers,or any combinationof thesepersons
mayresultfromone-handedoperation.Achain
saw is intended for two-handed use.
2. Do not operate a chain saw when you are fa-
tigued.
3. Use safety footwear; snug-fitting clothing; pro-
tectivegloves; and eye,hearing andhead pro-
tection devices.
4. Use caution when handling fuel. Move the
chain saw at least 10 feet (3 m) from the fuel-
ing point before starting the engine.
5. Do not allowotherpersonsto be nearthechain
sawwhenstartingorcuttingwiththe 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.

3
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 to-
ward you or pull you off balance.
13.When cutting a limb that is under tension, be
alert for springback so that you will not be
struck when the tension in the wood fibers is
released.
14.Keep th 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 specifcally trained to do so.
17.All chain saw service, other than the items
listed in the operator’s manual maintenance
instructions, should be performed by compe-
tent chain saw service personnel. (For ex-
ample, if improper tools are used to remove
the flywheel or if an improper tool is used to
holdthe flywheel inorder to removethe 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 gude bar scabbard.
19.Sparkarrester mufflersapproved to SAEStan-
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-
rester screen.

GENERAL
Kickback
[NOTE]
ReadtheECHO“CHAINSAWSAFETYMANUAL”included
withyour chain saw foradditional cutting and safety instruc-
tions.
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 com-
mon 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.
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.)
CAUTION
Do not let the tip of the bar touch anything while the
engine is running. At cutting speed the chain is mov-
ing, 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!
CAUTION
Wear suitable hearing protective device such as ear-
muffs or earplugs to protect against objectionable or
uncomfortable loud noises.
CUTTING INSTRUCTIONS

A falling tree can seriously damage anything it may hit - a
car, a house, a fence, a powerline, or another tree. There
are ways to make a tree fall where you want it, so first de-
cide 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.Whenthe tree begins to fall you shouldretreataway
from the direction of fall at a 45 degree angle to avoid the
trunk kicking back over the stump.

LIMBING
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 po-
sition of this notch is important since the tree will try to fall
“into” the notch. The felling out is made on the side oppo-
site 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 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 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.

11
Don’t cut with the saw overhead or the bar in a verticle
position. If the saw should kick back you may no have good
enough control to prevent possible injury.

KICKBACK
• Improperthrustcutting.
• Whenthebar nose hits anothertree,etc.
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.
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.
WARNING: KICKBACK ISDANGEROUS
Kickback is generated when the rotation of the chain is ar-
rested 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 to-
wards the operator.
The chain saw industry and government agencies have at-
tempted to presecribe various safety devices, but the best
protection is to avoid kickback.
Comply with the Safety Precautions as listed on page 2 of
this manual.
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.
