The components of this machine generate an electromagnetic
field during operation, which can interfere with some
pacemakers. 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 and Extreme Conditions
Prolonged exposure to cold and/or vibration can result in injury.
Read and follow all safety and operation instructions to
minimize risk of injury. Failure to follow instructions can 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 can result.
Do not operate this product indoors or in inadequately
ventilated areas. Engine exhaust contains poisonous emissions
and can cause serious injury or death.

AHS262 OPERATION
X7502342403 19
© 08/21 ECHO Incorporated
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 fresh (purchased within the last 30 days from the pump) 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. 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 2-stroke engine oil, such as Shindaiwa branded 2-stroke
oils, meeting ISO-L-EGD (ISO/CD 13738) and J.A.S.O. FD Standards must
be used. Shindaiwa 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 certified oil will void the 2-
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 AHS262
20 X7502342403
© 08/21 ECHO Incorporated
◆WEAR SAFETY GLASSES when mixing or handling.
◆AVOID repeated or prolonged skin contact.
◆AVOID inhaling oil mists or vapors.
Shindaiwa branded 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.
