WARNING
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.

4
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 require-
ments 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 tting, 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.
Keep long hair away from engine and air 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 exer-
cises during frequent work breaks, and also by not smoking.
• Limit the hours of operation. Try to ll 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 ngers fol-
lowed by whitening and loss of feeling, consult your physician before
further exposing yourself to cold and vibration.

Op E r a t O r 'sMa n u a l 5
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 move-
ment.
• 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 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.
• 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 rmly 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 mufer cover area will become very hot.
Avoid contact during and immediately after operation. Allow engine
and mufer to completely cool before performing any maintenance.

WARNING
Use only ECHO approved attachments. Serious injury may result from the use of a non approved attachment combi-
nation. Read and comply with all safety instructions listed in this operator manual. ECHO, INC. will not be respon-
sible for the failure of attachments or accessories which have not been tested and approved by ECHO.
• Check unit for loose/missing nuts, bolts, and screws. Tighten and/or replace as needed.
• Check that the auger is rmly attached and in safe operating condition.
• Ice blades are very sharp. Wear gloves when handling or replacing.
• Do not use any attachment, accessory, or replacement part unless it is recommended in the Operator's Manual.
• Have repairs done only by an authorized ECHO Service Dealer.
WARNING
Moving parts can amputate ngers or cause severe injuries. Keep hands, clothing and loose objects away from all
openings.
• ALWAys stop engine, disconnect spark plug, and make sure all moving parts have come to a complete stop
before removing obstructions, clearing debris, or servicing unit.
• DO NOT start or operate unit unless all guards and protective covers are properly assembled to unit.
• NEVER reach into any opening while the engine is running. Moving parts may not be visible through openings.
WARNING
Check fuel system for leaks due to fuel tank damage, especially if the unit is dropped. If damage or leaks are found,
do not use unit, otherwise serious personal injury or property damage may occur. Have unit repaired by an autho-
rized servicing dealer before using.
