W ARNING DANGER
• This unit can be dangerous and cause serious injury if improperly
used. To reduce injury risk to operator, helpers and bystanders, read
and understand the Operator's and Safety manuals.
• Blindness can occur from objects that are thrown or ricocheted even
with shield in place. Operators, helpers and bystanders must wear
ANSI Z87.1 approved eye protection.
• Always wear hearing protection when operating unit.
• Prevent accidental contact with unit and any cutting attachment.
Maintain a 50 ft. (15M) radius, DANGER ZONE surrounding the
operator. ONLY the operator, dressed in proper protective clothing
should be in the DANGER ZONE.
• Beware of KICKOUT (blade thrust) when using blades. Special
precautions are necessary for blade operation, see your Operator's
and Safety Manuals. ONLY install ECHO approved blades on Brush
Cutters (SRM) models equipped with proper blade shield, U-handles,
harness, blade collar, nut and cotter pin.
• Blade/Cutting attachment does not stop immediately after releasing
throttle. Keep hands and feet clear of blade/cutting attachment unless

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/brush cutter.
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.
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.
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.
Hearing Protection
ECHO recommends wearing hearing protection whenever
unit is used.
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 issecurely
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.

exhaust area clear of flammable debris.
14. FUEL TANK - Contains fuel and fuel filter.
15. RECOIL STARTER HANDLE/ROPE - Pull recoil starter handle/rope using light pulling force, approximately 2/3
(2 ft.) of rope length. Two (2) to Six (6) pulls are required to properly tension starter spring prior to automatic engine
engagement. DO NOT let handle snap back or damage to unit will occur.
16. FUEL TANK CAP - Covers and seals fuel tank opening.
17. PRIMER BULB - Pumping primer bulb before starting engine draws fresh fuel from the fuel tank priming the carburetor
for starting. Pump primer bulb until fuel is visible and flows freely in the clear fuel tank return line. Pump bulb an
additional 4 or 5 times.
