W ARNING DANGER
Power Blower users risk injury to themselves and others if the power blower is used improperly or safety precautions
are not followed. Proper clothing and safety gear must be worn when operating a blower.
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 blower.
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 face mask to protect against dust.
Hearing Protection --
ECHO recommends wearing hearing protection whenever
unit is used.
Proper Clothing --
Wear snug fitting, durable clothing;
• Pants should have long legs, shirts with long sleeves.
• DO NOT WEAR SHORTS,
• DO NOT WEAR TIES, SCARVES, 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.

EXTENDED OPERA TION/EXTREME CONDITIONS
Vibration and Cold --
It is believed that a condition called Raynaud’s Phenomenon, which
affects the fingers of certain individual 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 blower 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.
Repetitive Stress Injuries --
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.
EQUIPMENT
Before operation a complete check of the unit must be performed:
• Check unit for loose/missing nuts, bolts and screws. Tighten and/or
replace as needed.
• Inspect fuel lines, tank and area around carburetor for fuel leaks. DO
NOT operate unit if leaks are found.
• Keep exhaust area clear of flammable debris. Avoid contact during
and immediately after operation.

SAFE OPERATION
Determine Operation Area --
• Review area to be cleared. Look for potential hazards
such as stones or metal objects.
• Spectators and fellow workers must be warned, and
children and animals prevented from coming nearer than
15 m (50 ft.) while the blower is in use.
• Take wind conditions into account: avoid open doors
and windows.
• Provide all operators of this equipment with the
Operator's Manual and instructions for safe operation.
• Do not point blower at people or animals.
• Start unit on ground with throttle at idle. Check that
blower pipe is not blocked by the ground or by any
objects.
W ARNING DANGER
Do not operate this product indoors or in inadequately ventilated areas. Engine exhaust contains
poisonous emissions and can cause serious injury or
death.
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 perform Maintenance or Assembly procedures
with engine running.
Noise Control
• Follow local noise regulations on sound levels and
hours of operations. Use only during appropriate hours.
• Never use a higher speed setting then necessary to
perform a task. The higher the engine speed the louder
the blower noise.
• Be a good neighbor.
Avoid Hot Surfaces
• During operation, the muffler or catalytic muffler and
surrounding cover may become extremely hot. Avoid
contact during and immediately after operation. Always
keep exhaust area clear of flammable debris. Allow the
engine and muffler to completely cool before performing
any maintenance activity.
Keep A Firm Grip
• Hold handle with fingers together encircling the handle.
