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 employer should be
used; otherwise, sung fitting 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 fire, restart your chain saw
at least 3 m from the fueling area.
4. When using a chain saw a fire
extinguisher should be available.
5. When felling, keep at least 2 tree lengths
between yourself 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 starting the chain saw and
control the chain saw with a firm grip
on both handles when it is in operation.
Keep handles dry, clean and free of oil.
A chain saw should never be carried
with the engine running. When carrying
a chain saw with the engine running,
push the front hand guard forward to
engage the chain brake.
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 assembled. 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 standing tree unless
specifically 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 firm grip, thumbs and fingers
encircling the handles.
(e) Don’t overreach.
(f) Avoid cutting above shoulder height.
(g) Follow the manufacture’s instructions
for sharpening 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 sufficiently large so as to introduce the
entire nose (tip) of the guide bar. This
technique should reduce the danger of
kickback.
14. A chain saw is intended for two-handed
use. Serious injury to the operator,
helpers and/or bystanders 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 being 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
is alert for spring-back.

OPERATOR SAFETY
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 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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 fill 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 fingers, followed by whitening

CUTTING INSTRUCTION
GENERAL
CAUTION
•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.
•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!
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.
Some material may adversely affect the housings
of your chain saw.
(Example palm Tree Acid, fertilizer etc.)
To avoid housing deterioration, carefully remove all
packed sawdust around clutch and guide bar area
and wash with water. Coat metal parts with light oil.
Kickback

FELLING THE 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.
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 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 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
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.
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.
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.
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.
DANGER
•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 backwards
towards the operator.
