injury may occur.
Users of this product risk injury to themselves and others if the
unit is used improperly and/or safety precautions are not
followed. Proper clothing and safety gear must be worn when
operating unit.
Physical Condition
Your judgment and physical dexterity may not be good:
Operate unit only if you are physically and mentally well.
Eye Protection
◆ Eye protection that meets ANSI Z87.1 or CE requirements
must be worn whenever you operate the unit.
◆ For additional safety, a full-face shield may be worn over
safety glasses or goggles to provide protection from sharp
branches or flying debris.
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.
Keep long hair away from engine and air intake. Retain hair with cap or net.
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.
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.
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.
Read the Manual
• Provide all users of this equipment with literature for instructions on safe
operation.
Clear the Work Area
• Clear the area of children, bystanders, and pets. At a minimum, keep all
children, bystanders, and pets outside a 15 m (50 ft.) radius; outside the
15 m (50 ft.) zone, there is still a risk of injury from thrown objects.
Bystanders should be encouraged to wear eye protection. If you are
approached, stop the engine.
• Avoid blowing debris towards people, pets, open windows, or vehicles
when using unit.
• Review area to be cleared. Look for potential hazards such as stones or
metal objects.
Keep a Firm Grip
• To prevent from dropping the unit, hold the handle in one hand, with
thumb and fingers encircling the handle.
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 flammable debris.
Avoid contact during and immediately after
operation.
Use only approved attachments. Serious injury may result from
the use of a non-approved attachment combination. ECHO, INC.
will not be responsible for the failure of cutting devices,
attachments or accessories which have not been tested and
approved by ECHO. Read and comply with all safety
instructions listed in this manual.

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.
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. 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-LEGD (ISO/CD 13738) and J.A.S.O. M345-FD certified oil will void the twostroke 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
ECHO branded 2-stroke oils may be mixed at 50:1 ratio for
application in all ECHO 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. Mark fuel containers as
containing 2-stroke mixture fuel.
◆ 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.
1.Fill an approved fuel container
with half of the required
amount of gasoline.
2.Add the proper amount of
2-stroke oil to gasoline.
3.Close container and shake to
mix oil with gasoline.
4.Add remaining gasoline, close
fuel container, and remix.
Spilled fuel is a leading cause of hydrocarbon emissions. Some
states may require the use of automatic fuel shut-off containers to
reduce fuel spillage.
• Empty the fuel tank prior to storing the unit. Return unused fuel to an
approved fuel storage container.
Storage - Fuel storage laws vary by locality. Contact your
local government for the laws affecting your area. As a
precaution, store fuel in an approved, airtight container.
Store in a well-ventilated, unoccupied building, away from
sparks and flames.
Stored fuel ages. Do not mix more fuel than you expect to use in 30
days, 90 days when a fuel stabilizer is added.
Stored two-stroke fuel may separate. ALWAYS shake fuel container
thoroughly before each use.
Used oil and gasoline, and soiled towels are hazardous waste
materials. Disposal laws vary by locality.

position, close choke - COLD START position - to stall engine.
Have your dealer repair stop switch before using unit again.
Operating Blower
Engine exhaust IS HOT, and contains Carbon Monoxide (CO), a
poison gas. Breathing CO can cause unconsciousness, serious
injury, or death. Exhaust can cause serious burns. ALWAYS
position unit so that exhaust is directed away from your face
and body.
Always wear safety glasses, hearing protection and a face filter
mask or serious personal injury may result. Do not point the
blower pipe in the direction of people or pets.
Use reduced speed only when performing light-duty tasks or to
comply with local noise regulations. Continuous low speed operation
may allow fuel/oil residue to build-up on the piston and cause rapid
build-up of carbon on the spark arrestor screen, resulting in
overheating and engine damage. To reduce harmful build-up, run
engine at wide open throttle for at least 5 minutes every hour, and
inspect/clean the spark arrestor screen after approximately 40 hours
of operation.
Read the Safety Section carefully.
To avoid engine damage due to over-revving, do not block blower
pipe.
1.Use only during appropriate hours. Contact your local government for
the ordinances affecting your area.
2.To reduce sound levels, limit the number of pieces of equipment used at
any one time.
3.Allow the engine to warm up at a fast idle for a few minutes.
Moving parts can amputate fingers 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 complete stop before removing
obstructions, clearing debris, or servicing unit. Allow unit to
cool before performing service. Wear gloves to protect hands
from sharp edges and hot surfaces.
Operating a poorly maintained unit can result in serious injuries
to operator or bystanders. Always follow all maintenance
instructions as written, otherwise serious personal injury may
result.
Your unit is designed to provide many hours of trouble free service. Regular
scheduled maintenance will help your unit achieve that goal. If you are
unsure or are not equipped with the necessary tools, we recommend that
you take your unit to a Servicing Dealer for maintenance. To help you decide
whether you want to DO-IT-YOURSELF or have the Dealer do it, each
maintenance task has been graded. If the task is not listed, see your Dealer
for repairs.

Note: Federal EPA regulations require all model year 2012 and later
gasoline powered engines produced for sale in the United
States to be equipped with a special low permeation fuel
supply hose between the carburetor and fuel tank. When
servicing model year 2012 and later equipment, only fuel
supply hoses certified by EPA can be used to replace the
original equipment supply hose. Fines up to $37,500 may be
enforced for using an un-certified replacement part.
Use only NGK CMR7H spark plug otherwise severe engine damage
may occur.
1.Remove spark plug and check
for fouling, worn and rounded
center electrode.
2.Clean the plug or replace with a
new one. DO NOT sand blast to
clean. Remaining sand will
damage engine.
3.Adjust spark plug gap by
bending outer electrode.
4.Tighten spark plug to 102-153 kgf • cm (86-133 in • lbf).
Cooling System
Level 2.
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.
Cleaning Grill
1.Brush accumulated debris from intake grill between backpack frame
and blower housing.
Cleaning Cylinder Fins
1.Disconnect spark plug lead
from spark plug.
2.Remove engine cover.
3.Clean cylinder fins (A) to allow
cooling air to pass freely.
4.Install engine cover.
5.Connect spark plug lead.
Exhaust System
Spark Arrestor Screen
Level 2.
Parts Required:Spark Arrestor Screen
Carbon deposits in muffler will cause a drop in engine output and
overheating. Spark arrestor screen must be checked periodically.
1.Disconnect spark plug lead
from spark plug.
2.Remove engine cover.
3.Remove spark arrestor screen
(C) from muffler. Replace
screen if plugged with carbon
