PERSONAL CONDITION AND SAFETY EQUIPMENT

W ARNING DANGER

Earth Auger users risk injury to themselves and others if the auger is used improperly, or safety precautions are not followed. Proper clothing and safety gear must be worn when operating an auger.

Ignition ON/OFF

"Run"

Position

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 Earth Auger handles. Gloves also reduce the transmission of machine vibration to your hands.

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 non-skid soles;

• DO NOT WEAR OPEN TOED SHOES,

• DO NOT OPERATE UNIT BAREFOOTED.

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 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 trimmer 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.

EARTH AUGER

OPERATOR'S MANUAL

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.

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.

• Provide all operators of this equipment with the operator's manual, and instructions for safe operation.

• Review area to be augered. Beware of underground hazards such as electrical lines, gas lines, water mains, or cable and telephone lines.

• Never use ice auger without checking with local authorities for safe ice thickness in lakes, ponds, and rivers.

• Spectators and coworkers must be warned, and children and animals prevented from coming nearer than 3 m (10 ft.) while auger is in use.

• Before starting the unit, equip yourself, and any person helping you, with the required Protective Equipment and Clothing. Do not wear loose or baggy clothing while operating the auger.

• Do not allow children to operate auger at any time.

• Always keep hands, arms, legs, and feet clear of the rotating auger.

• Do not carry the auger between holes with the engine running.

• Always shut engine off before making any repairs.

• Always hold auger handles firmly with both hands during operation.

• Maintain stable footing and balance at all times. Do not stand on slippery, uneven, or unstable surfaces.

• Do not operate auger in any position other than upright.

• During operation, the muffler cover area will become very hot. Avoid contact during and immediately after operation. Allow engine and muffler to completely cool before performing any maintenance.
