•Always use face or dust mask if operation is dusty.
•For additional safety, a full-face shield may be worn over safety glasses or goggles to provide
protection from sharp branches or flying debris.
Hand Protection
Wear sturdy, no-slip, rubber work gloves to improve your grip on the handles. Gloves also provide protection
against cuts and scratches, cold environments, and reduce the transmission of machine vibration to your
hands.
Hearing/Ear Protection
ECHO recommends wearing hearing protection whenever unit is used.
Dust Protection
Operators who are sensitive to dust or other common airborne allergens may need to wear a dust mask to
prevent inhaling these materials while operating unit. Dust masks can provide protection against dust, plant
debris, and other plant matter such as pollen. Make sure the mask does not impair your vision, and replace
the mask as needed to prevent air restrictions.
Proper Clothing
Wear snug-fitting, durable clothing:
• Pants should have long legs, shirts should have long sleeves.
• DO NOT WEAR SHORTS.
• DO NOT WEAR TIES, SCARVES, JEWELRY, or clothing with loose or hanging items that could become

The components of this machine generate an electromagnetic field during operation, which may
interfere with some pacemakers.To reduce the risk of serious or fatal injury, persons with
pacemakers should consult with their physician and the pacemaker manufacturer before operating
this machine.In the absence of such information, ECHO does not recommend the use of ECHO
products by anyone who has a pacemaker.
Extended Operation / Extreme Conditions
Prolonged exposure to cold and/or vibration may result in injury. Read and follow all safety and
operation instructions to minimize risk of injury. Failure to follow instructions may result in painful
wrist/hand/arm injuries.
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.
Repetitive Stress Injuries (RSI)
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.

8X7508161200
© 3/2014 ECHO Inc.
SAFETY DSRM-200
• 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.
Read the Manual
Provide all users of this equipment with the Instruction Manual
for instructions on safe operation.
Keep a Firm Grip
Always hold throttle handle and support handle with thumbs and
fingers tightly 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
Avoid contact during and immediately after operation.

Operation
Careless operation, misuse, improper configuration or assembly, or use of unapproved cutting
heads and work attachments can result in serious or fatal injuries to operator and bystanders. Flying
debris can cause serious eye injury, loss of sight, or property damage. You must read, understand,
and follow all safety and operating instructions in this manual.
• ALWAYS maintain a minimum safety zone of 50 feet (15 meters) from where you are working. Don’t allow
others to enter the safety zone unless you have shut the unit off and the trimmer head has completely
stopped moving.
• ALWAYS clear the intended cutting/work area of debris such as wire, stones, wood, cans, broken glass,
and other objects which could be thrown, become entangled, or damage the cutting head.
• ALWAYS maintain a direct line of sight to the trimmer head and the area where trimming/work is being
performed. Be aware of what lies in the path of the trimmer head at all times.
• NEVER work in the dark or when visibility of the work area is poor.
• ALWAYS be alert for changes in operation that could signal a problem - sudden vibration and unusual
noise require immediate attention. Stop the unit and correct any problems before resuming cutting.
• NEVER carry unit around the work site while the trimmer head is rotating. ALWAYS let the trimmer head
stop before lifting the unit and moving to a new position.
• Keep debris flow directed away from operator to minimize risk of being struck and injured by flying debris.
Debris flows in direction of line head rotation at point of cutting contact. Change line head position as
needed to change debris flow.
• NEVER operate trimmer with cutter head above knee height - operation with the cutter head well above
ground level produces a higher debris flow, and can cause debris to strike you in the face.
• Contact with spinning nylon line will cause serious injury. Keep hands, feet, and all other body parts away
from cutter head.
• Always switch off the unit and remove the battery when transporting the unit.
