personal condition and safety equipment
WARNING
Hedge Clipper users risk injury to themselves and others if the hedge clipper is used improperly and or safety
precautions are not followed. Proper clothing and safety gear must be worn when operating a hedge clipper.
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
Eye protection that meets ANSI Z87.1 or CE requirements
must be worn whenever you operate the unit.
Hand Protection
Wear no-slip, heavy duty work gloves to improve your
grip on the handles. Gloves also reduce the transmission of
machine vibration to your hands.
Hearing Protection
Wear 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, SCARFS, JEWELRY.
Wear sturdy work shoes with nonskid soles;
• DO NOT WEAR OPEN TOED SHOES,
• DO NOT OPERATE UNIT BAREFOOTED.
Wear no-slip, heavy duty work gloves.
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 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 unit 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.
Hedge Clipper
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.
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.
Keep a Firm Grip
• Hold the front and rear handles with both hands, with thumbs and
fingers 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.

Tools required: T27 Torx L-Wrench, 25 - 50 mm (1 - 2 in.)
Cleaning Brush,
Parts Required: None.
IMPORTANT
To maintain proper engine operating temperatures, cooling air
must pass freely through the cylinder fin area. This flow of air carries combustion heat away from the engine.
Overheating and engine seizure can occur when:
• Air intakes are blocked, preventing cooling air from reaching the cylinder.
• Dust and grass build up on the outside of the cylinder. This build
up insulates the engine and prevents the heat from leaving.
Removal of cooling passage blockages or cleaning of cooling fins is
considered “Normal Maintenance.” Any failure attributed to lack of
maintenance is not warranted.
1. Remove spark plug lead.
2. Remove air cleaner cover (A).
3. Remove 2 engine cover screws and engine cover (B).
