PERSONAL
CONDITION AND SAFETY EQUIPMENT
W ARNING DANGER
Trimmer/Brush Cutter users risk injury to themselves and others if the trimmer/brush cutter is used improperly
or safety precautions are not followed. Proper clothing and safety gear must be worn when operating a
trimmer.
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 trimmer.
Hand Protection
Wear no-slip, heavy duty work gloves to improve your
grip on the Trimmer/Brush Cutter 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.
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 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.
6
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.
EQUIPMENT
W ARNING DANGER
Use only ECHO-approved attachments. Serious injury may result from the use of a non-approved attachment
combination. ECHO, INC. will not be responsible for the failure of cutting devices, attachments, or accessories
which have not been tested and approved by ECHO. Read and comply with all safety instructions listed in this
manual and safety manual.
• Check unit for loose/missing nuts, bolts and screws. Tighten and/or
replace as needed.
• Inspect fuel lines, tank, and area around carburetor for fuel leaks. DO
NOT operate unit if leaks are found.
• Inspect shield for damage, and ensure that the cut-off knife is
securely in place. Replace if either is damaged or missing.
• Check that the cutting attachment is firmly attached and in safe
operating condition.
• Check that front loop handle and shoulder strap/ or shoulder/
waist harness are adjusted for safe, comfortable operation. See
Assembly Section for proper adjustment.
• Keep exhaust area clear of flammable debris. Avoid contact during
and immediately after operation.
