EXTENDED OPERATION/EXTREME CONDITIONS
Vibration and Cold
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
recommendedbecause the minimumexposure which mighttriggerthe
ailmentisunknown.
• 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 blower 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
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).AnextremeRSIconditionisCarpalTunnelSyndrome
(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.
• Takeperiodicbreakstominimizerepeti-
tion and rest your hands.
• Reduce the speed and force in which you
do the repetitive movement.
• Do exercises to strengthen the hand and
armmuscles.
• 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
likelypermanentnerveand muscle
damage can be prevented.
EQUIPMENT
• Check unit for loose/missing nuts, bolts and screws. Tighten
and/or replace as needed.
• Inspect fuel lines, tank and area around carburetor for fuel leaks. DO
NOT operate unit if leaks are found.
• Do not use blower if any part is missing or damaged.
• Have repairs done only by an authorized ECHO Service dealer.
• Do not use any attachment, accessory or replacement part unless it is
recommended in this Operator's Manual.
• Avoid contact during and immediately after operation. Always keep
exhaustarea clearof flammabledebris. Allowtheengine andmuffler
to completely cool before performing any maintenance activity.

SAFE OPERATION
WARNING DANGER
Do not operate this product indoors or in inadequately ventilated
areas. Engine exhaust contains poisonous emissions and can cause
serious injury or death.
• Review area to be cleared. Look for potential hazards such as stones
or metal objects.
• Spectators and fellow workers must be warned, and children and
animalspreventedfromcomingnearer than15 m(50 ft.)while the
blower is in use.
• Take wind conditions into account: avoid open doors and windows.
• Provide all operators of this equipment with the Operator's Manual
and instructions for safe operation.
• Do not point blower at people or animals.
KeepAFirmGrip
• Hold handles with fingers together encircling handles.
KeepASolidStance
• 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 perform Maintenance or Assembly procedures with engine
running.
NoiseControl
• Follow local noise regulations on sound
levels and hours of operations. Use only
during appropriate hours.
• Never use a higher speed setting then
necessary to perform a task. The higher
the engine speed the louder the blower
noise.
• Be a good neighbor.
AvoidHotSurfaces
• Duringoperation, the muffler or catalytic
muffler and surrounding cover may
become extremely hot. Avoid contact
duringand immediatelyafter operation.
Always keep exhaust area clear of
flammabledebris. Allow theengineand
mufflertocompletelycoolbefore

IMPORTANT
To maintain proper engine operating temperatures, cooling air must
pass freely through the cylinder fin area. This flow of air carries
combustion heat away from the engine.
Overheating and engine seizure can occur when:
• Air intakes are blocked, preventing cooling air from reaching the
cylinder.
• Dust and grass build up on the outside of the cylinder. This build up
insulates the engine and prevents the heat from leaving.
Removal of cooling passage blockages or cleaning of cooling fins is
considered “Normal Maintenance”. Any failure attributed to lack of
maintenance is not warranted.
