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 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.

T302X SAFETY
X7502350302 11

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.
• Reduce the speed and force with
which you do the repetitive
movement.
• Do exercises to strengthen the hand and arm muscles.

SAFETY T302X
12 X7502350302
© 10/19 ECHO Incorporated
• 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 communications 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.
Read Manuals
• Provide all users of this equipment with literature for instructions on safe
operation.
Clear The Work Area
• Always clear the work area of foreign objects such as rocks, broken glass,
nails, wire, or string,, and check for any hidden hazards. Spectators and
fellow workers must be warned, and children and animals prevented from
coming nearer than 50 ft. (15 m) while the unit is in use.
• Outside the 15 m (50 ft) zone, there is still a risk of injury from thrown
objects.
• Bystanders should be encouraged to wear eye protection.
• If you are approached, stop the engine and cutting attachment.
• When a bladed unit is used, there is the added risk of injury to bystanders
being struck with the moving blade in the event of a blade thrust or other
unexpected reaction of the blade.
Keep A Firm Grip
• Always hold throttle handle and support handle with thumbs and fingers
tightly encircling the handles.

ready for use.
◆DO NOT start or operate unit unless all guards and
protective covers are properly assembled to unit.
◆NEVER reach into any opening while the engine is running.
Moving parts may not be visible through openings.
◆Position wiring safely to prevent snagging, separation of
connectors, or breakage during operation. Gather excess
wire, and secure with wiring clamp if provided on
equipment, or tuck behind the air filter area. Do not place
wiring directly against hot engine components.
◆Check wiring and connectors for nicks, cuts, exposed wire,
or other damage, and repair or replace as needed. Exposed
wire or connectors can cause shocks, sparks, and risk of
fire or explosion, resulting in serious injury.
◆Check wire terminals for secure connections.
Periodically Check fuel system (fuel lines, vent, grommet, fuel
tank, and fuel cap) for leaks especially if the unit is dropped. If
