WARNING
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.

4
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 sen-
sations, 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 exer-
cises during frequent work breaks, and also by not smoking.
• Limit the hours of operation. Try to ll each day with jobs where
operating the trimmer or other hand-held power equipment is not
required.
• If you experience discomfort, redness and swelling of the ngers fol-
lowed by whitening and loss of feeling, consult your physician before
further exposing yourself to cold and vibration.
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
Eye protection that meets ANSI Z87.1 or CE requirements
must be worn whenever you operate the unit.
Hand Protection
Wear no-slip, heavy duty work gloves to improve your
grip on the handles. Gloves also reduce the transmission
of machine vibration to your hands.
Hearing Protection
Wear hearing protection. ECHO recommends wearing
hearing protection whenever unit is used.
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 be-
come entangled in moving parts.
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 informa-
tion, ECHO does not recommend the use of ECHO products by anyone who has a pacemaker.

OpEratOr'sManual 5
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 move-
ment.
• 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.
• Provide all operators of this equipment with the operator's manual,
and instructions for safe operation.
• Review area to be augered. Beware of underground hazards such as
electrical lines, gas lines, water mains, or cable and telephone lines.
• Never use ice auger without checking with local authorities for safe
ice thickness in lakes, ponds, and rivers.
• Spectators and coworkers must be warned, and children and animals
prevented from coming nearer than 3 m (10 ft.) while auger is in use.
• Before starting the unit, equip yourself, and any person helping you,
with the required Protective Equipment and Clothing. Do not wear
loose or baggy clothing while operating the auger.
• Do not allow children to operate auger at any time.
• Always keep hands, arms, legs, and feet clear of the rotating auger.
• Do not carry the auger between holes with the engine running.
• Always shut engine off before making any repairs.
• Always hold auger handles rmly with both hands during operation.
• Maintain stable footing and balance at all times. Do not stand on
slippery, uneven, or unstable surfaces.
• Do not operate auger in any position other than upright.
• During operation, the mufer cover area will become very hot.
Avoid contact during and immediately after operation. Allow engine
and mufer to completely cool before performing any maintenance.

performance, or severe engine damage and void the product warranty. Read and follow instructions in the Storage
section of this manual.
fuel
WARNING
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 alternative fuels may cause performance prob-
lems, loss of power, overheating, fuel vapor lock, and unintended machine operation, including, but not limited to,
improper clutch engagement. Alternative fuels may also cause premature deterioration of fuel lines, gaskets, carbu-
retors and other engine components.
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 complete

IMPORTANT
Echo premium Power Blend X TM Universal 2-Stroke Oil may be mixed at 50:1 ratio for application in all Echo en-
gines sold in the past regardless of ratio specied in those manuals.
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.
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. Echo brand premium Power Blend X TM Universal 2-Stroke Oil meets these standards. Engine problems due to in-
adequate lubrication caused by failure to use an ISO-L-EGD (ISO/CD 13738) and J.A.S.O. FD certied oil, such as Echo
premium Power Blend X TM, will void the two-stroke engine warranty.
WARNING
Operation of this equipment may create sparks that can start res. is unit is equipped with a spark arrestor to pre-
vent discharge of hot particles from the engine. Metal blade use also can create sparks if the blade strikes rocks, metal,
or other hard objects. Contact local re authorities for laws or regulations regarding re prevention requirements.

Mixing Instructions
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.
IMPORTANT
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.
After use
• DO NOT store a unit with fuel in its tank. Leaks can occur. Return
unused fuel to an approved fuel storage container.
Storage - Fuel storage laws vary by locality. Contact your local gov-
ernment 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 ames.
IMPORTANT
Stored fuel ages. Do not mix more fuel than you expect to use in
thirty (30) days, ninety (90) days when a fuel stabilizer is added.
IMPORTANT
Stored two-stroke fuel may separate. ALWAYS shake fuel con-
tainer thoroughly before each use.
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!

Level 1.
Parts required: REPOWERTM Tune-Up Kit
NOTE
Always brush dirt and debris away from air cleaner area prior to
cleaning air lter.
1. Brush dirt off air cleaner area. Keep dirt away from engine and air
intake grid.
2. Remove air lter cover. Brush dirt from inside cover and away
from edges of air lter.
3. Check air lter seal for tight t with air lter case.
4. Remove air lter from case. Use care to prevent dirt and debris
from falling into air lter case.
5. Inspect lter element and seal. Replace lter if any of these prob-
lems are present:
•Air lter seal does not t tightly against case
•Air lter seal is distorted, worn, or damaged
•Air lter element has holes or other damage
•Air lter element is saturated with dirt
•Air lter element is soaked with fuel mix
6. If air lter is in good condition and can be cleaned and reused,
lightly brush debris from air lter element, or blow lter element
clean using low pressure (40 psi or less) compressed air directed at
inside of lter.
IMPORTANT
When using compressed air, always direct air stream at inside sur-
face of lter so dust and debris will be blown out of lter. Keep air
nozzle 6 - 8 inches away from lter to prevent damage to lter.
7. Install air lter in case, and replace cover.
NOTICE
Actual replacement interval for air lter depends on operating con-
ditions. Operation in dustier applications requires more frequent
cleaning and replacement. Continued operation with a damaged
or excessively dirty lter will allow dirt and debris to enter engine,
and result in poor performance, rapid engine wear, and premature
engine failure.

fuel fIlTer
Level 1.
Parts required: REPOWERTM Tune-Up Kit
DANGER
Fuel is VERY ammable. Use extreme care when mixing, storing
or handling.
1. Use a clean rag to remove loose dirt from around fuel cap and
empty fuel tank.
2. Use the “fuel line hook” to pull the fuel line and lter from the
tank.
3. Remove the lter from the line and install the new lter.
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 certied by EPA
can be used to replace the original equipment supply hose. Fines up
to $37,500 may be enforced for using an un-certied replacement
part.

CoolIng sysTem
Level 2.
Parts Required: None.
IMPORTANT
To maintain proper engine operating temperatures, cooling air
must pass freely through the cylinder n area. This ow 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 debris 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 and cleaning of cooling ns is
considered “Normal Maintenance.” Any failure attributed to lack of
maintenance is not warranted.
1. Periodically blow dirt and debris off cooling ns with a compressor
and safety nozzle, or;
2. Remove engine and mufer covers, and brush off dirt and debris
using the medium bristle brush.
