Eye Protection
◆Eye protection that meets ANSI Z87.1 or CE requirements
must be worn whenever you operate the unit.
◆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 han-
dles. Gloves also provide protection against cuts and scratches, cold envi-
ronments, and reduce the transmission of machine vibration to your hands.
Hearing/Ear Protection
ECHO recommends wearing hearing protection whenever unit is used.
Breathing 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 entangled in moving parts or surround-
ing growth.

ENGLISH
Keep long hair away from engine and air intake. Retain hair with cap or net.
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.
The components of this machine generate an electromagnetic
field during operation, which may interfere with some pacemak-
ers. To reduce the risk of serious or fatal injury, persons with
pacemakers should consult with their physician and the pace-
maker manufacturer before operating this machine. In the ab-
sence of such information, ECHO does not recommend the use
of this machine by anyone who has a pacemaker.
Extended Operation / Extreme Conditions
Prolonged exposure to cold and/or vibration may result in inju-
ry. Read and follow all safety and operation instructions to min-
imize 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 mini-
mum 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 exer-
cises during frequent work
breaks, and also by not smoking.
• Limit the hours of operation. Try to
fill each day with jobs where oper-
ating the unit or other hand-held
power equipment is not required.

SAFETY SRM-225
10 X7702092207

• 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, numb-
ness, 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 Syn-
drome (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 mus-
cle damage can be prevented.
All over head electrical conductors and communications wires
can have electricity flow with high voltages. This unit is not in-
sulated against electrical current. Never touch wires directly or
indirectly, otherwise serious injury or death may result.

ed areas. Engine exhaust contains poisonous emissions and
can cause serious injury or death.
Guide Bar and Saw Chain
◆Serious injury may result from the use of non approved
guide bar and saw chain combinations. Read and comply
with all safety instructions listed in this manual.
◆ECHO, INC. will not be responsible for the failure of cutting
devices or accessories which have not been tested and

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.
Use Proper Clothing & Equipment
• Always wear head protection with full face shield to help protect against
falling branches and debris.
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
• During operation, the drive shaft
housing and attachment bearing
housing may become very hot, too
hot to touch. Avoid contact during
and immediately after operation.
Kickback
Kickback can lead to dangerous loss of control of the Power
Pruner and result in serious injury to the operator or any one
standingclose by. HoldthePower Prunerfirmlywithboth hands
with thumbs and fingers encircling the front and rear handles.
Be aware of the down and outward path the pruner will take after
the cut is made.

SRM-225 SAFETY
X7702092207 13
© 2/2017 ECHO Inc.
ENGLISH
Kickback may occur when the moving saw
chain at the nose or tip of the guide bar
touches an object, or when the wood
closes in and pinches the saw chain in the
cut. In some cases this may cause a light-
ning-fast reverse action, kicking the guide
bar and saw chain up and back or down
and back towards the operator. Either of
these reactions may cause the operator to
lose control of the Power PrunerTM which
could result in serious personal injury.
With a basic understanding of kickback,
you can reduce or eliminate the element of
surprise which contributes to accidents.
Avoid contact of the guide bar tip with any object while the saw chain is mov-
ing.
Cut only wood. Avoid striking concrete, metal, wire, or other obstructions
which could cause kickback or damage to the saw chain.
If the saw chain does strike a foreign object, immediately stop the engine,
inspect and repair the Power PrunerTM if necessary.
Equipment

injury may result from the use of this attachment combined
with a non approved ECHO product.
• Check unit for loose/missing nuts, bolts, and screws. Tighten and/or
replace as needed.
• Inspect shield for damage and that shield is securely in place. Replace if
shield is damaged or missing.
• Check that the cutting attachment is firmly attached and in safe operating
condition.
