• 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.
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.
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.
Keep a Firm Grip
• Hold the support handle and throttle handle with thumbs and fingers encircling the grips.
• 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.
Avoid Hot Surfaces
• During operation, the drive shaft housing and attachment bearing
housing may become very hot, too hot to touch. Avoid contact
during and immediately after operation.
Never perform blade maintenance procedures while engine is running.

To maintain proper engine operating temperatures, cooling air must pass freely through the cylinder fin area.
This flow of air carries combustion heat away from the engine.
Overheating and engine seizure can occur when:
• Air intakes are blocked, preventing cooling air from reaching
the cylinder.
• Dust and grass build up on the outside of the cylinder. This
build up insulates the engine and prevents the heat from
leaving.
Removal of cooling passage blockages or cleaning of cooling
fins is considered “Normal Maintenance.” Any failure attributed
to lack of maintenance is not warranted.

L-EGD (ISO/CD 13738) and JASO M345FD Standards. The use of two-stroke oils designed for other applications, such as for outboard motors
or lawnmowers can result in severe engine damage, and will void your two-stroke engine limited warranty.

oil, will void the two-stroke engine limited warranty. ECHO Power Blend™ Two-Stroke Oil meets the ISO-L-EGD and JASO M345FD
Standard. Emission related parts are covered for 5 years homeowner use or 2 years commercial use regardless of two-stroke oil used, per
the statement listed in the EPA or California Emission Defect Warranty Explanation.
• Damage caused by use of gasohol, containing methanol (wood alcohol), or gasoline containing less than 89 octane. Only use gasoline which
contains 89 octane or higher. Gasohol which contains a PD[LPXP 10% ethanol (grain alcohol) or 15% MTBE (methyl/tertiary/butyl/ether)
is also approved. The prescribed mixing ratio of gasoline to oil is listed on the ECHO oil label and covered in your operator’s manual.
• Incorrect storage procedures, stale fuel, including failure to provide or perform required maintenance services as prescribed in the operator's
manual. Preventative maintenance as outlined in the operators manual is the customer’s responsibility.

• Certain parts and other items are not warranted, including but not limited to: lubricants, starter cords, and engine tune-ups.
• Use of spark plugs other than those meeting performance and durability requirements of the OEM spark plug listed in the Operator's
Manuals.
• Overheating or carbon scoring failures due to restricted, clogged exhaust port or combustion chamber, including damage to spark arrester
