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 handle. Gloves also reduce the transmission
of machine vibration to your hands.
Hearing Protection
ECHO recommends wearing hearing protection when-
ever 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 protective hair covering to contain long hair.
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 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.
WARNING
Users of this product risk injury to themselves and others if the unit is used improperly and/or safety precautions
are not followed. Proper clothing and safety gear must be worn when operating unit.
PERSONAL CONDITION AND SAFETY EQUIPMENT
Extended Operation/Extreme Conditions
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 recom-
mended, 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.

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.
Avoid Hot Surfaces
• Keep exhaust area clear of flammable debris. Avoid contact during
and immediately after operation.
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 exercise 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.

DESCRIPTION
Locate this safety decal on your unit. The complete unit illustration, found in the "DESCRIPTION" section, will help you

Shaft Decal
1. DRIVE SHAFT ASSEMBLY - Contains a specially designed liner and the flexible drive shaft.
2. NYLON CUTTING ATTACHMENT - Contains replaceable nylon trimming line that advances when the trimmer head
is tapped against the ground while the head is turning at normal operating speed.
3. CUT-OFF KNIFE - Automatically trims line to the correct length: 5 in. after head is tapped on the ground. If trimmer is
operated without a cut-off knife the line will become too long, the engine will overheat and engine damage may occur.
4. PLASTIC DEBRIS SHIELD ASSEMBLY - Shield assembly includes the Cut-Off Knife and Safety Decal. Helps
protect the operator by deflecting debris produced during the trimming operation. This shield must be replaced with
the steel shield for blade use.
