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 han-
dles. Gloves also provide protection against cuts and scratches, cold envi-
ronments, 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 surround-
ing growth.
• Keep clothing buttoned or zipped, and keep shirt tails tucked in.
Wear sturdy work shoes with nonskid rubber soles:
• 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 pacemak-
ers. To reduce the risk of serious or fatal injury, persons with
pacemakers should consult with their physician and the pace-
maker manufacturer before operating this machine. In the ab-
sence of such information, ECHO does not recommend
the use
of this machine by anyone who has a pacemaker.
Extended Operation / Extreme Conditions
Prolonged exposure to cold and/or vibration may result in inju-
ry. Read and follow all safety and operation instructions to min-
imize 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 mini-
mum 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 exer-
cises during frequent work
breaks, and also by not smoking.
• Limit the hours of operation. Try to
fill each day with jobs where oper-
ating the unit or other hand-held
power equipment is not required.
• If you experience discomfort, red-
ness, and swelling of the fingers followed by whitening and loss of feeling,
consult your physician before further exposing yourself to cold and vibra-
tion.

Repetitive Stress Injuries
(RSI)
It is believed that overusing the
muscles and tendons of the fingers,
hands, arms, and shoulders may
cause soreness, swelling, numb-
ness, 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 Syn-
drome (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 exercises 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 mus-
cle damage can be prevented.
All over head electrical conductors and communications wires
can have electricity flow with high voltages. This unit is not in-
sulated 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
• 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.
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.
Equipment
Use this attachment with ECHO approved models only. Serious
injury may result from the use of this attachment combined with
a non approved ECHO product.
• Check unit for loose/missing nuts, bolts, and screws. Tighten and/or
replace as needed.
• Inspect shield for damage and make sure it is securely in place. Replace
if shield is damaged or missing.
• Check that the cutting attachment is firmly attached and in safe operating
condition.
80-Tooth blade requires professional sharpening.
