Rules for safe operation
1. General precautions
Operator's manual
Read the operator's manual for your chain saw carefully.
Be thoroughly familiar with the chain saw's controls and how to use the chain saw properly.
Failure to follow instructions could lead to personal injury.
If you have any questions or problems, please contact your ECHO dealer.
Physical condition
Do not operate a chain saw when you are fatigued or under the influence of alcohol or
drugs.
You should be in good physical and mental health in order to handle your chain saw safely.
Errors in judgement or execution can be serious or fatal.
If you have any physical condition which strenuous work could worsen, check with your
physician before using a chain saw.
Do not operate when ill or fatigued, or under the influence of any substance or medication
which could affect your vision, dexterity or judgement.
Personal equipment
Always wear approved goggles to protect your eyes.
Wood chips, dust, snapping branches and other debris can be thrown by the cutting chain
into the operator's facial area.
Goggles may also offer limited protection in the event of the cutting chain hitting the
operator in the eye area.
If conditions warrant that a ventilated face shield be worn, goggles must be worn
underneath it.
ECHO advises wearing hearing protection at all times.
If not followed, hearing loss can occur.
You should reduce the risk of hearing damage by wearing either "headset" type protectors
or ear plugs which are approved by an authorized organization.
All persons who make part of their living using chain saws should be tested periodically for
hearing deterioration.
Always wear a cap or hat when working with a chain saw.
A safety hard hat is highly recommended when felling or working under trees, or when
objects can fall on you.
Wear heavy duty, non-slip gloves for improved grip, and also for protection against cold and
vibration.
Safety tip shoes or boots with non-slip sole should be worn.
Never wear loose clothing, unbuttoned jackets, flared sleeves and cuffs, scarves,
tie-strings, neckties, cords, chains, jewellery, etc. which could snag the saw chain or
underbrush.
Clothing should be of sturdy, protective material.
It should be snug-fitting to resist snagging, but roomy enough for freedom of movement.
Trouser legs should not be flared or cuffed, and should be either tucked into the boot tops
or trimmed short.
Safety vests, leg chaps and logger's pants of ballistic material are available.
It is the operator's responsibility to wear such additional protection if conditions warrant it.
Never operate a chain saw when you are alone.
Arrange to have someone remain within calling distance in case you need help.
CAUTION
Stuffing ears with cotton is not recommended.

Fuel
1. Oil tank cap
2. Fuel tank cap
A: Tightening direction
Use an appropriate type of fuel container.
Bring an extinguisher or shovel in case of fire.
Despite the precautions which can be taken, operating a chain saw, or just working in the
forest, presents dangers.
Do not smoke or bring flame or sparks near to fuel supplies.
The fuel tank may be under pressure.
Always loosen the fuel cap and wait for pressure to be equalized before removing the cap.
Fill the fuel tank outdoors over bare ground and install the fuel cap securely.
Do not pour fuel indoors.
Wipe any spilled fuel off the unit.
Never refuel while the engine is still hot, or fuel a running engine.
Do not store the unit with fuel in its tank, because a fuel leak could start a fire.
Starting engine
Move the chain saw at least 3 m from the fuelling point before starting the engine.
Do not allow other persons to be near the chain saw when you are starting or cutting with
the chain saw.
Keep bystanders and animals out of the work area.
Do not let anyone hold wood for you to cut.
Do not start cutting until you have a clear work area, secure footing and a planned retreat
path from the falling tree.
Before you start the engine, make sure that the saw chain is not contacting anything.
Keep the handles dry, clean, and free of oil or fuel mixture.
Operate the chain saw only in well-ventilated areas.
Exhaust gas, oil mist (from chain saw lubrication) or saw dust is harmful to health.
Transportation
1. Guide bar cover
When transporting your chain saw, use the appropriate guide bar cover.
Carry the chain saw with the engine stopped, the guide bar and saw chain to the rear, and
the silencer away from your body.
DANGER
Petrol and fuel are extremely flammable.
If spilled or ignited by ignition source, it can cause fire and serious injury or
property damage.
Extreme caution is required when handling petrol or fuel.
After refuelling, tighten fuel cap firmly and check for leakage.
In case of fuel leakage, repair before starting operation since there is a danger of
fire.

2. Kickback safety precautions
In some cases, tip contact may cause a lightning-fast reverse reaction, kicking the guide
bar up and back toward the operator (this is called a rotational kickback).
Pinching the saw chain along the top of the guide bar may push the guide bar rapidly back
toward the operator (this is called a linear kickback).
Either or these reactions may cause you to lose control of the saw and come in contact with
the moving chain, which could result in serious personal injury.
As a chain saw user, you should take several steps to keep your cutting jobs free from
accident or injury.
With a basic understanding of kickback, you can reduce or eliminate the element of
surprise.
Sudden surprise contributes to accidents.
Understand that rotational kickback is preventable by keeping an unshielded bar nose from
touching an object or the ground.
Do not operate a chain saw with one hand!
Serious injury to the operator, helpers or bystanders may result from one-handed operation.
For proper control, always use two hands when operating a chain saw, one of which
operates the trigger.
Otherwise, this can result in the chain saw "skating" or skidding, which can result in
personal injury due to loss of control.
Keep a good firm grip on the saw which both hands, with 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.
Two hands must be used to control the saw at all times.
Do not overreach or cut above chest height.
Make sure that the area in which you are cutting is free from obstructions.
Do not let the bar nose contact a log, branch, or any other obstruction which could be hit
while you are operating the saw.
Cutting at high engine speeds may reduce the likelihood of kickback.
But cutting at part-throttle or low engine speeds may be preferable to control the chain saw
in tight situations and may also reduce the likelihood of kickback.
Follow manufacturer's sharpening and maintenance instructions for the saw chain.
Use only replacement guide bars and chains specified by the manufacturer, or the
acceptable equivalents of these guide bars and chains.
DANGER
Kickback safety precaution for chain saw users: 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.

3. Other safety precautions
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 cold and vibration.
Accordingly, your ECHO chain saw has shock mounts designed to reduce the intensity of
vibration received through the handles.
Exposure to cold and vibration may cause tingling and burning followed by loss of color and
numbness in the fingers.
We strongly recommend you take the following precautions 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 chain saw operation.
Try to fill a part of each work day with jobs other than chain sawing.
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 injuries
It is believed that over-using the muscles and tendons of the fingers, hands, arms and
shoulders may cause soreness, swelling, numbness, weakness and extreme pain to the
areas just mentioned.
To reduce the risk of repetitive stress injury, do the following:
Avoid using your wrist in a bent, extended or twisted position.
Instead, try to maintain a straight wrist position.
Also, when grasping, use your whole hand, not just the thumb and index finger.
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 the hand and arm muscles.
See a doctor if you feel tingling, numbness or pain in the fingers, hands, wrists or arms.

Machine conditions
Do not operate a chain saw that is damaged, improperly adjusted, or not completely and
securely assembled.
Do not operate the chain saw with a loose or defective silencer.
Be sure that the saw chain stops moving when the throttle control trigger is released.
Cutting
Do not operate a chain saw in a tree unless you have been specifically trained to do so.
Keep all parts of your body away from the saw chain when the engine is running.
Use extreme caution when cutting small-size brush and saplings because slender material
may catch the saw chain and be whipped toward you or pull you off balance.
Stay on the uphill side when bucking or limbing logs which might roll when cut.
When cutting a limb that is under tension, be alert for spring-back so that you will not be
struck by the limb or chain saw when the tension in the wood fibers is released.
Cutting while on a ladder is extremely dangerous because the ladder can slip and your
control of the chain saw is limited.
Working aloft should be left to professionals.
Keep both feet on the ground.
Do not work from off-the-ground positions.
Stop the engine before setting the chain saw down.
Wood practices
Operating a chain saw safely requires a chain saw in proper working order, sound
judgement, and knowledge of the methods which should be applied in each cutting
situation.
Do not let any person use your saw unless he has read this operator's manual and fully
understands its instructions.
Use your saw only to cut wood or wood products.
Do not cut solid metal, sheet metal, plastics or any non-wood materials.
Services
All chain saw service operations, other than items listed in the operator's manual
maintenance instructions, should be performed by competent service personnel.
(For example, if an improper tool is used to hold the flywheel in order to remove the clutch,
structural damage to the flywheel could occur and subsequently could cause the flywheel
to burst.)
WARNING
Do not modify a chain saw in any way.
Only attachments and parts supplied by ECHO or expressly approved by ECHO for
use with the specific ECHO chain saw models are authorized.
Although certain unauthorized attachments are useable with the ECHO powerhead,
their use may, in fact, be extremely dangerous.
CAUTION
Do not touch hot surfaces of cylinder cover and silencer after you used the chain saw.
