WARNING

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 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.

oP e r a t o r 's Ma n u a l

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.

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 windows.

• 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 slippery, 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 during and immediately after operation.
