RULES FOR SAFE OPERATION
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.
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 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 finger, 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
repetitive movement.
• Do exercises to strengthen hand and arm
muscles.
• See a doctor if you feel tingling, numbness or
pain in your fingers, 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 ANSI
Z 87.1 requirements.
Goggles meeting the requirements have the
mark “Z 87” 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 fitting durable clothing should be worn.
Pants should have long legs, DO NOT WEAR
SHORTS.
Do not wear loose fitting 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.
HOT HUMID WEATHER
• Heavy protective clothing can increase
operator fatigue 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 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.
