Personal Condition and Safety Equipment
Users of this product risk injury to themselves and others if the unit is used improperly and/or safety
precautions are not followed. Proper clothing and safety gear must be worn when operating unit.
Physical Condition
Your judgment and physical dexterity may not be good:
• If you are tired or sick.
• If you are taking medication.
• If you have taken alcohol or drugs.
Operate unit only if you are physically and mentally well.
Eye Protection
•Eye protection that meets ANSI Z87.1 or CE requirements must be worn whenever you operate the
unit.
•For additional safety, a full-face shield may be worn over safety glasses or goggles to provide
protection from sharp branches or flying debris.
Hand Protection
Wear sturdy, no-slip, rubber work gloves to improve your grip on the handles. Gloves also provide protection
against cuts and scratches, cold environments, and reduce the transmission of machine vibration to your
hands.
Hearing/Ear Protection
ECHO recommends wearing hearing protection whenever unit is used.
Breathing Protection
Operators who are sensitive to dust or other common airborne allergens may need to wear a dust mask to
prevent inhaling these materials while operating unit. Dust masks can provide protection against dust, plant
debris, and other plant matter such as pollen. Make sure the mask does not impair your vision, and replace
the mask as needed to prevent air restrictions.
Proper Clothing
Wear snug-fitting, durable clothing:
• Pants should have long legs, shirts should have long sleeves.
• DO NOT WEAR SHORTS.
• DO NOT WEAR TIES, SCARVES, JEWELRY, or clothing with loose or hanging items that could become
entangled in moving parts or surrounding growth.
• Keep clothing buttoned or zipped, and keep shirt tails tucked in.
Wear sturdy work shoes with nonskid rubber soles:

PPT-266/H SAFETY
X7702096005 7
© 08/2014 ECHO Inc.
• DO NOT WEAR OPEN TOED SHOES.
• DO NOT OPERATE UNIT BAREFOOTED.
Keep long hair away from engine and air intake. Retain hair with cap or net.
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.
The components of this machine generate an electromagnetic field during operation, which may
interfere with some pacemakers.To reduce the risk of serious or fatal injury, persons with
pacemakers should consult with their physician and the pacemaker manufacturer before operating
this machine.In the absence of such information, ECHO does not recommend the use of ECHO
products by anyone who has a pacemaker.
Extended Operation / Extreme Conditions
Prolonged exposure to cold and/or vibration may result in injury. Read and follow all safety and
operation instructions to minimize risk of injury. Failure to follow instructions may result in painful
wrist/hand/arm injuries.
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 sensations, 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, neck, feet, ankles,
hands, and wrists.
• Maintain good blood circulation by performing vigorous arm
exercises during frequent work breaks, and also by not
smoking.
• Limit the hours of operation. Try to fill each day with jobs
where operating the unit 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.

8X7702096005

SAFETY PPT-266/H
Repetitive Stress Injuries (RSI)
It is believed that overusing the muscles and tendons of the
fingers, hands, arms, and shoulders may cause soreness,
swelling, numbness, weakness, and extreme pain in those
areas. 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. 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 with which you do the repetitive movement.
• Do exercise to strengthen the hand and arm muscles.
• Immediately stop using all power equipment and consult a doctor if you feel tingling, numbness, or pain in
the fingers, hands, wrists, or arms. The sooner RSI/CTS is diagnosed, the more likely permanent nerve
and muscle damage can be prevented.
All over head electrical conductors and communications wires can have electricity flow with high
voltages. This unit is not insulated against electrical current. Never touch wires directly or indirectly,
otherwise serious injury or death may result.
Do not operate this product indoors or in inadequately ventilated areas. Engine exhaust contains
poisonous emissions and can cause serious injury or death.
Read the Manuals
• Provide all users of this equipment with the Operator’s Manual
and Safety Manual for instructions on Safe Operation.
Clear the Work Area
• Spectators and fellow workers must be warned, and children
and animals prevented from coming nearer than 15 m (50 ft.)
while the unit is in use.
Use Proper Clothing & Equipment
• Always wear head protection with full face shield to help
protect against falling branches and debris.

PPT-266/H SAFETY
X7702096005 9
© 08/2014 ECHO Inc.
Keep a Firm Grip
• Always hold throttle handle and support handle with thumbs
and fingers tightly encircling the handles.
Keep a Solid Stance
• Maintain footing and balance at all times. Do not stand on
slippery, uneven or unstable surfaces. Do not work in odd positions or on ladders. Do not over reach.
• Operate the Power PrunerTM only from the ground or out of an approved bucket lift.
• Always evaluate the branches to be pruned for hazards such as loose dead branches which may fall and
strike the operator or helpers. Remove hazards before pruning.
• Plan retreat path from falling objects.
• Cut branches bounce when striking ground.
• Check that shoulder harness is adjusted for safe, comfortable operation.
• Turn the Power PrunerTM off when moving from tree to tree.
• Avoid any contact with saw chain.
Avoid Hot Surfaces
• Keep exhaust area clear of flammable debris. Avoid contact
during and immediately after operation.
Kickback
Kickback can lead to dangerous loss of control of the Power PrunerTM and result in serious injury to
the operator or any one standing close by. Hold the Power PrunerTM firmly with both hands with
thumbs and fingers encircling the front and rear handles. Be aware of the down and outward path
the pruner will take after the cut is made.
Kickback may occur when the moving saw chain at 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. In some cases this may cause a
lightning-fast reverse action, kicking the guide bar and saw chain
up and back or down and back towards the operator. Either of
these reactions may cause the operator to lose control of the
Power PrunerTM which could result in serious personal injury.
With a basic understanding of kickback, you can reduce or
eliminate the element of surprise which contributes to accidents.
Avoid contact of the guide bar tip with any object while the saw
chain is moving.
Cut only wood. Avoid striking concrete, metal, wire, or other
obstructions which could cause kickback or damage to the saw
chain.

Fuel is VERY flammable. Use extreme care when mixing, storing or handling, or serious personal
injury may result.
•Use an approved fuel container.
•DO NOT smoke near fuel.
•DO NOT allow flames or sparks near fuel.
•Fuel tanks/cans may be under pressure. Always loosen fuel caps slowly allowing pressure to
equalize.
•NEVER refuel a unit when the engine is HOT or RUNNING!
•DO NOT fill fuel tanks indoors. ALWAYS fill fuel tanks outdoors over bare ground.
•DO NOT overfill fuel tank. Wipe up spills immediately.
•Securely tighten fuel tank cap and close fuel container after refueling.
•Inspect for fuel leakage. If fuel leakage is found, do not start or operate unit until leakage is
repaired.
•Move at least 3m (10 ft.) from refueling location before starting the engine.
Mixing Instructions
1. Fill an approved fuel container with half of the required
amount of gasoline.
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.
Spilled fuel is a leading cause of hydrocarbon emissions. Some
states may require the use of automatic fuel shut-off containers
to reduce fuel spillage.
After use
• DO NOT store a unit with fuel in its tank. Leaks can occur.
Return unused fuel to an approved fuel storage container.
