PERSONAL CONDITION AND SAFETY EQUIPMENT

WARNING 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,

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.

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.

OPERATOR'S MANUAL

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.

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.
