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:
• 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 this machine 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.

66001 SAFETY
X7712093101 9

ENGLISH
• 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
(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 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
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.
