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.

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.
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.
• 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.

ENGLISH
Fuel
Diesel fuels and alternative fuels, such as E15 (15% ethanol),
E85 (85% ethanol) or any fuels not meeting Shindaiwa
requirements are NOT approved for use in Shindaiwa 2-stroke
or Hybrid 4-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.
Fuel Requirements
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 alcohol) is NOT approved. ECHO Red Armor Fuel™(Power Fuel™) is
93 octane, ethanol-free fuel premixed with ECHO Red Armor®engine oil at
50:1 ratio. Use of ECHO Red Armor Fuel™(Power 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 meeting ISO-L-EGD (ISO/CD
13738) and J.A.S.O. FD Standards must be used. Shindaiwa brand 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 certified oil, such as Shindaiwa brand 2-stroke oils, will void the
two-stroke engine warranty.
2-Stroke engine oil contains petroleum distillates and other
additives that may be harmful if swallowed. Heated oil can
release vapors that can cause flash fire, or ignite with explosive
force. Read and follow the oil manufacturer’s instructions, and
observe all safety warnings and precautions for handling
flammable liquids. For more detailed safety and first 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.

OPERATION T302
20 X7502350700
© 4/2018 ECHO Inc.
◆WEAR SAFETY GLASSES when mixing or handling.
◆AVOID repeated or prolonged skin contact
◆AVOID inhaling oil mists or vapors.
Shindaiwa brand 2-stroke oils may be mixed at 50:1 ratio for
application in all Shindaiwa engines sold in the past, regardless of
ratio specified in those manuals.
Handling Fuel
Fuel is VERY flammable. 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 flames 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 fill fuel tanks indoors. ALWAYS fill fuel tanks
outdoors over bare ground.
◆DO NOT overfill 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.
Gasoline vapor is heavier than air, and can travel along the
ground to nearby sources of ignition such as electrical motors,
pilot lights, and hot or running engines. Vapors ignited by an
ignition source can flash back to the fuel container, resulting in
an explosion, fire, serious or fatal injuries, and extensive
property damage.
