PB-755S H/T SAFETY
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:
• 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 generat e an electromagnetic field
during operation, which may interfere with some pacemakers. To
reduce the risk of serious or fata l injury, persons with pacemakers
should consult with their physician and the pa cemaker
manufacturer before operating this machine. In the absence of
such information, ECHO does not recommend
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.
the use of this
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.

PB-755S H/T SAFETY
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 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.
All over head electrical conductors and communicat ions wires can
have electricity flow with high voltages. This unit is not insulated
against electrical current. Never touch wires directly or indirectly,
otherwise serious injury or death may result.
Do not operate this product indoors or in inadequately ventilated
areas. Engine exhaust contains poisonous emissions and can
cause serious injury or death.
