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
Wear eye protection that meets ANSI Z87.1 or CE requirements whenever you operate the unit.
Hand Protection
Wear no-slip, heavy-duty work gloves to improve your grip on the blower handle. Gloves also reduce the transmission
of machine vibration to your hands.
Breathing Protection
Wear a facemask to protect against dust.
Hearing Protection
ECHO recommends wearing hearing protection whenever unit is used.
Proper Clothing
Wear snug tting, durable clothing;
• Pants should have long legs, shirts with long sleeves.
• DO NOT WEAR SHORTS,
• DO NOT WEAR TIES, SCARVES, and JEWELRY.
Wear sturdy work shoes with nonskid soles:
• DO NOT WEAR OPEN TOED SHOES,
• DO NOT OPERATE UNIT BAREFOOTED.
Keep long hair away from engine and blower intake. Retain hair with cap or net.
Hot Humid Weather
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.
Vibration and Cold
It is believed that a condition called Raynaud’s Phenomenon, which affects the ngers of certain individuals, may be
brought about by exposure to vibration and cold. Exposure to vibration and cold may cause tingling and burning sen-
sations, followed by loss of color and numbness in the ngers. 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 ll 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 ngers
followed by whitening and loss of feeling, consult your physician
before further exposing yourself to cold and vibration.

DANGER
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.
• Take wind conditions into account: avoid open doors and win-
dows.
• Do not point blower at people or animals.
Keep a Firm Grip
• Hold the front and rear handles with both hands, with thumbs and
ngers encircling the handles.
Keep a Solid Stance
• Maintain footing and balance at all times. Do not stand on slip-
pery, uneven or unstable surfaces. Do not work in odd positions
or on ladders. Do not over reach.
Avoid Hot Surfaces
• Keep exhaust area clear of ammable debris. Avoid contact dur-
ing and immediately after operation.
Repetitive Stress Injuries
It is believed that overusing the muscles and tendons of the ngers, 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
nger.
• 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 doc-
tor if you feel tingling, numbness, or pain in the ngers, hands,
wrists, or arms. The sooner RSI/CTS is diagnosed, the more
likely permanent nerve and muscle damage can be prevented.
