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,
Hearing Protection
ECHO recommends wearing hearing protection whenever
unit is used.
• if you are taking medication,
• if you have taken alcohol or drugs.
Operate unit only if you are physically and mentally well.

Wear snug fitting, durable clothing;
• Pants should have long legs, shirts with long sleeves.

transmission of machine vibration to your hands.

Vibration and Cold
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.
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.

SAFE OPERATION
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.
Determine Operation Area
• Review area to be cleared. Look for potential hazards such as stones
or metal objects.
• Take wind conditions into account: avoid open doors and windows.
• 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.
Read the Manuals
• Provide all users of this equipment with the Operator's Manual and
Safety Manual for instructions on Safe Operation.
Keep A Firm Grip
• Hold handle with fingers together encircling the handle.
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.
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 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.
