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
Wear eye protection that meets ANSI Z87.1 or CSA Z94.3
requirements whenever you operate the unit.
Hand Protection
Wear no-slip, heavy-duty work gloves to improve your
grip on the blower handle. Gloves also reduce the trans-
mission of machine vibration to your hands.
Breathing Protection
Wear a facemask to protect against dust.
Hearing Protection
Shindaiwa recommends wearing hearing protection when-
ever unit is used.
Vibration and Cold
It is believed that a condition called Raynaud’s Phenomenon, which affects the ngers 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 ngers. 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 ll 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 ngers followed by whitening and loss of feeling, con-
sult your physician before further exposing yourself to cold and vibration.
Proper Clothing
Wear snug tting, durable clothing;
• Pants should have long legs, shirts with 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..
Wear sturdy work shoes with nonskid soles;
• DO NOT WEAR OPEN TOED SHOES,
• DO NOT OPERATE UNIT BAREFOOTED.
Wear no-slip, heavy duty work gloves.
Keep long hair away from engine and air intake. Retain
hair with cap or net.
Hot Humid Weather
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.
WARNING
The ignition components of this machine generate an electromagnetic eld 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, Shindaiwa does not recommend the use of Shindaiwa products by anyone who has a pacemaker.

Read the Manuals
• Provide all users of this equipment with the Operator’s Manual
for instructions on Safe Operation.
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.
• Take wind conditions into account: avoid open doors and
windows.
• Do not point blower at people or animals.
Keep a Firm Grip
• Hold the front and rear handles with both hands, with thumbs
and ngers encircling the handles.
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 over reach.
Avoid Hot Surfaces
• Keep exhaust area clear of ammable debris. Avoid contact
during and immediately after operation.
Repetitive Stress Injuries
It is believed that overusing the muscles and tendons of the ngers, 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
nger.
• 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 ngers, hands,
wrists, or arms. The sooner RSI/CTS is diagnosed, the more
likely permanent nerve and muscle damage can be prevented.
DANGER
Do not operate this product indoors or in inadequately ventilated
areas. Engine exhaust contains poisonous emissions and can
cause serious injury or death.

OPERATION
WARNING
Operation of this equipment may create sparks that can start res around dry vegetation. This unit is equipped
with a spark arrestor to prevent discharge of hot particles from the engine. Contact local re authorities for
laws or regulations regarding re prevention requirements.
WARNING
Moving parts can amputate ngers or cause severe injuries. Keep hands, clothing and loose objects away from
all openings. Always stop engine, disconnect spark plug, and make sure all moving parts have come to a com�
plete stop before removing obstructions, clearing debris, or servicing unit. Blower housing may contain shred�
der blades and other sharp edges that can cause serious injuries if touched, even if engine is off and blades are
not moving. Wear gloves to protect hands from sharp edges and hot surfaces.
WARNING
• Always maintain a direct, clear line of site to the unit and the work being performed.
• Always be alert for changes in operation of unit.
• Always shut engine off before transporting unit to new location.
Gasoline - Use 89 Octane [R+M/2] (mid grade or higher) gasoline known to be good quality. Gasoline may contain up to
10% Ethanol (grain alcohol) or 15% MTBE (methyl tertiary-butyl ether). Gasoline containing methanol (wood alco-
hol) is NOT approved. Use of ECHO branded fuel is recommended to extend engine life in all air-cooled 2-stroke and
2/4-stroke hybrid engines.
Two Stroke Oil - A two-stroke engine oil, such as ECHO branded 2-stroke oils, meeting ISO-L-EGD (ISO/CD 13738)
and J.A.S.O. FD Standards must be used. ECHO branded 2-stroke oils meet these standards. Engine problems due to
inadequate lubrication caused by failure to use an ISO-L-EGD (ISO/CD 13738) and J.A.S.O. M345-FD certied oil will
void the two-stroke engine warranty.
Fuel Requirements
WARNING
Engine exhaust IS HOT, and contains Carbon Monoxide (CO), a poison gas. Breathing CO can cause uncon�
sciousness, serious injury, or death. Exhaust can cause serious burns. ALWAYS position unit so that exhaust is
directed away from your face and body.
WARNING
Diesel fuels and alternative fuels, such as E-15 (15% ethanol), E -85 (85% ethanol) or any fuels not meeting
ECHO requirements are NOT approved for use in ECHO 2-stroke gasoline engines. Use of diesel or alternative
fuels may cause performance problems, loss of power, overheating, fuel vapor lock, and unintended machine
operation, including, but not limited to, improper clutch engagement. Diesel or alternative fuels may also cause
premature deterioration of fuel lines, gaskets, carburetors and other engine components

11
Handling Fuel
DANGER
Fuel is VERY ammable. Use extreme care when mixing, storing or handling or serious personal injury may result.
• Use an approved fuel container.
• DO NOT smoke near fuel.
• DO NOT allow ames or sparks near fuel.
• Fuel tanks/cans may be under pressure. Always loosen fuel caps slowly allowing pressure to equalize.
• NEVER refuel a unit when the engine is HOT or RUNNING!
• DO NOT ll fuel tanks indoors. ALWAYS ll fuel tanks outdoors over bare ground.
• DO NOT overll fuel tank. Wipe up spills immediately.
• Securely tighten fuel tank cap and close fuel container after refueling.
• Inspect for fuel leakage. If fuel leakage is found, do not start or operate unit until leakage is repaired.
• Move at least 3 m (10 ft.) from refueling location before starting the engine.
WARNING
2-Stroke engine oil contains petroleum distillates and other additives that may be harmful if swallowed. Heated oil can
release vapors that can cause ash re, or ignite with explosive force. Read and follow the oil manufacturer’s instruc�
tions, and observe all safety warnings and precautions for handling ammable liquids. For more detailed safety and rst
aid information, visit www.echo-usa.com for a copy of the Material Safety Data Sheet.
• KEEP OUT OF REACH OF CHILDREN.
• If swallowed, do not induce vomiting. CALL PHYSICIAN OR A POISON CONTROL CENTER IMMEDIATELY.
• WEAR SAFETY GLASSES when mixing or handling.
• AVOID repeated or prolonged skin contact
• AVOID inhaling oil mists or vapors.
DANGER
Gasoline vapor is heavier than air, and can travel along the ground to nearby sources of ignition such as electrical mo�
tors, pilot lights, and hot or running engines. Vapors ignited by an ignition source can ash back to the fuel container,
resulting in an explosion, re, serious or fatal injuries, and extensive property damage.
NOTICE
