PERSONAL CONDITION AND SAFETY EQUIPMENT
W ARNING DANGER
Power Blower users risk injury to themselves and others if the power blower is used improperly and
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.
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 15M (50 ft.) while the
blower is in use.
- Do not operate this product indoors or in inadequatly ventilated
areas..
- 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.

Use Proper Clothing & Equipment
- Before starting the unit, equip yourself and any other person
working within the 15M (50 ft.) Safety Zone with the required
Protective Equipment and clothing.
- Keep long hair away from engine and blower intake. Retain hair
with cap or net.
- Start unit on ground with throttle at idle. Check that blower pipe
is not blocked by the ground or by any objects.
Keep A Firm Grip
- Hold handle with fingers together encircling the handle.
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 exhaust area may become very hot, too hot to
touch. Avoid contact during and immediately after operation.

EXTENDED OPERATION/EXTREME CONDITIONS
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 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 & force in 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.
