W ARNING DANGER
Power Blower users risk injury to themselves and others if the power blower is used improperly or safety precautions
are not followed. Proper clothing and safety gear must be worn when operating a blower.

EXTENDED
OPERATION/EXTREME CONDITIONS
Vibration and Cold
It is believed that a condition called Raynaud’s Phenomenon, which
affects the fingers of certain individual 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
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.
EQUIPMENT
Before operation a complete check of the unit must be performed:
• 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.

SAFE OPERATION
W ARNING DANGER
Do not operate this product indoors or in inadequately ventilated areas. Engine exhaust contains poisonous
emissions and can cause serious injury or death.
Determine Operation Area
• Review area to be cleared. Look for potential hazards such as stones
or metal objects.
• Take wind conditions into account: avoid open doors and windows.
• Do not point blower at people or animals.
• Start unit on ground with throttle at idle. Check that blower pipe is
not blocked by the ground or by any objects.
Read the Manuals
• Provide all users of this equipment with the Operator's Manual and
Safety Manual for instructions on Safe Operation.
Keep A Firm Grip
• Hold handle with fingers together encircling the handle.
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.
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 perform Maintenance or Assembly procedures with engine
running.
Noise Control
• 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.
Avoid Hot Surfaces
• During operation, the muffler or catalytic
muffler and surrounding cover may
become extremely hot. Avoid contact
during and immediately after operation.
Always keep exhaust area clear of
flammable debris.
