Personal Condition and Safety Equipment

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.

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

◆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 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.

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:

X7722279402 9

SRM-225 SAFETY

• 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 surrounding

growth.

• Keep clothing buttoned or zipped, and keep shirt tails tucked in.

Wear sturdy work shoes with nonskid rubber 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.

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 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 this

machine 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.

SAFETY SRM-225

10 X7722279402

• 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.

• 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.
