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
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 trimmer 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, consult your physician
before further exposing yourself to cold and vibration.
personal condItIon and safety equIpment
WARNING
Pro Attachment SeriesTM users risk injury to themselves and others if the Pro Attachment SeriesTM unit is used im-
properly and or safety precautions are not followed. Proper clothing and safety gear must be worn when operating a
Pro Attachment SeriesTM unit.
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
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 informa-
tion, ECHO does not recommend the use of ECHO products by anyone who has a pacemaker.

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. In-
stead 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.
Read the Manuals
• Provide all users of this equipment with the Operator’s Manual and
Safety 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.
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 lad-
ders. Do not over reach.
Avoid Hot Surfaces
• Keep exhaust area clear of ammable debris. Avoid contact during
and immediately after operation.

NOTICE: Use of unmixed, improperly mixed, or fuel older than 90 days, (stale fuel), may cause hard starting, poor
performance, or severe engine damage and void the product warranty. Read and follow instructions in the Storage
section of this manual.
fuel
DANGER
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.
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 TM Universal 2-Stroke Oil meets these standards. Engine problems due to inad-
equate lubrication caused by failure to use an ISO-L-EGD and J.A.S.O. FD certied oil, such as Echo premium Power
Blend TM, will void the two-stroke engine warranty.
IMPORTANT
Echo premium Power Blend TM Universal 2-Stroke Oil may be mixed at 50:1 ratio for application in all Echo engines
sold in the past regardless of ratio specied in those manuals.

lations relating to re prevention requirements.

12
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 overll 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 3m (10 ft.) from refueling location before starting the engine.
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 container thor-
oughly before each use.

coolInG system
Level 2.
Parts Required: None if you are careful.
IMPORTANT
To maintain proper engine operating temperatures, cooling air
must pass freely through the cylinder n area. This ow of air car-
ries 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 ns is
considered “Normal Maintenance”. Any failure attributed to lack of
maintenance is not warranted.

carburetor adjustment
Engine Break-In
New engines must be operated a minimum duration of two tanks of fuel
break-in before carburetor adjustments can be made. During the break-
in period your engine performance will increase and exhaust emissions
will stabilize. Idle speed can be adjusted as required.
High Altitude Operation
This engine has been factory adjusted to maintain satisfactory starting,
emission, and durability performance up to 1,100 feet above sea level
(ASL) (96.0 kPa). To maintain proper engine operation and emission
compliance above 1,100 feet ASL the carburetor may need to be ad-
justed by an authorized ECHO service dealer.
IMPORTANT
If the engine is adjusted for operation above 1,100 feet ASL, the
carburetor must be re-adjusted when operating the engine below
1,100 feet ASL, otherwise severe engine damage may result.
Level 2.
Parts required: None.
NOTE
Every unit is run at the factory and the carburetor is set in compli-
ance with emission regulations. Carburetor adjustments, other than
idle speed, must be performed by an authorized ECHO dealer.
1. Check idle speed and reset if necessary. If a tachometer is avail-
able, idle speed screw (A) should be set to the specications found
on "Specications page" of this manual. Turn idle screw (A)
clockwise to increase idle speed; counter clockwise to decrease
idle speed.
WARNING
When carburetor adjustment is completed, the attachment should
not rotate at idle, otherwise serious personal injury may result.
