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
Wear eye protection that meets ANSI Z87.1 or CE requirements whenever you operate the unit.
Hand Protection
Wear no-slip, heavy-duty work gloves to improve your grip on the handle. Gloves also reduce the transmission of ma­chine vibration to your hands.
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, SCARFS, JEWELRY.
Wear protective hair covering to contain long hair.
Wear sturdy work shoes with nonskid soles;
• DO NOT WEAR OPEN TOED SHOES,
• DO NOT OPERATE UNIT BAREFOOTED.
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.
Extended Operation/Extreme Conditions
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 sensa-
tions, 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 unit 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.
Gr a s s Tr i m m e r /Br u s h Cu T T e r
Op e r a T O r 's ma n u a l
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 exercise 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 lad­ders. Do not over reach.
Avoid Hot Surfaces
• Keep exhaust area clear of ammable debris. Avoid contact during
and immediately after operation.

1-2000.1. Read the Operator’s Manual carefully. Be thoroughly familiar with the controls and proper use of the trimmer. Know how to stop the unit and disengage the controls.
WARNING
Grass/weed trimmers can throw gravel, stone, wood chips, glass, and plastic or metal objects. The debris shield behind the trimmer head stops much of the debris, but cannot prevent the operator from being struck by some debris. Read the rules for safe operation in the operator’s manual that you received with your echo trimmer. Also, follow all instructions in this instruction sheet.
1. REPLACING LINE
A. Remove spool by turning knob clockwise, “right”, and separating
parts.

1. Always use the end of the line for cutting. Forcing the cutter head
too close to the work will result in reduced efciency and broken
line.
2. Maintain the line at the recommended length of 12.5 to 15 cm (5
to 6 in). A longer line will reduce engine speed, a shorter line may result in engine damage.
3. The trimmer head rotates counterclockwise. Always cut with the
head tilted to the right to deect debris away from the operator.
4. Always observe the SAFETY RULES on Page 5 when using the
unit.

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 stop before removing obstructions, clearing debris, or servicing unit.
WARNING
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.
WARNING
Operation of this equipment may create sparks that can start res around dry vegetation. This unit is equipped with a spark arrestor and a spark arrestor may be required. The operator should contact local re agencies for laws or regulations relating to re prevention requirements.

b l a d e s e l e c t I o n

WARNING
The type of Blade used MUST be matched to the type and size of material cut. An improper or dull blade can cause serious personal injury. Blades MUST be sharp. Dull blades increase the chance of kick-out and injury to yourself and bystanders.
Gr a s s Tr i m m e r /Br u s h Cu T T e r
Plastic/Nylon Grass/Weed Blades may be used where ever the nylon line head is used. DO NOT use this blade for heavy weeds or brush!
8 Tooth Weed/Grass Blade is designed for grass, garden debris and thick weeds. DO NOT use this blade for brush or heavy woody growth, 19 mm (3/4 in.) diameter or larger.
Op e r a T O r 's ma n u a l
17
80 Tooth Brush Blade is designed for cutting brush and woody growth up to 13mm (3 in.) diameter.
22 Tooth Clearing Blade is designed for dense thickets and saplings up to 64 mm (3 in.) diameter.
Use Shoulder/Waist Harness Use of the Shoulder/Waist Harness is recommended for ALL Trimmer/Brush Cutter use, not just Blade oper­ation. The Shoulder/Waist Harness when used in a trimming operation with nylon line head suspends the trimmer from the operator's shoulder and reduces operator fatigue.
During blade operation, the same fatigue reduction is achieved. Safety to the operator is also enhanced by reducing the possibility of blade contact with the operator's hands and feet by restricting trimmer move­ment
WARNING
In case of emergency, pull the quick release latch to disconnect the trimmer from the harness.

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.
WARNING
Alternative fuels, such as E-20 (20% 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 problems, 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, 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.
Two Stroke Oil - A two-stroke engine oil meeting ISO-L-EGD (ISO/CD 13738) and J.A.S.O. FC/FD Standards must be used. Echo brand premium Power Blend X TM Universal 2-Stroke Oil meets 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. FC/FD certied oil, such as Echo premium Power Blend X TM, will void the two-stroke engine warranty.
IMPORTANT

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.

MAINTENANCE PROCEDURE NOTES:
ma I n t e n a n c e
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 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.
Your ECHO trimmer is designed to provide many hours of trouble free service. Regular scheduled maintenance will help your trimmer achieve that goal. If you are unsure or are not equipped with the necessary tools, you may want to take your unit to an ECHO Service Dealer for maintenance. To help you decide whether you want to DO-IT-YOURSELF or have the ECHO Dealer do it, each maintenance task has been graded. If the task is not listed, see your ECHO Dealer for repairs.
s k I l l l e v e l s
Level 1 = Easy to do. Common tools may be required. Level 2 = Moderate difculty. Some specialized tools may be required.
ECHO offers REPOWERTM Maintenance Kits and Parts to make your maintenance job easier.

Level 1.
Tools required: 25 - 50mm (1 - 2 in.) cleaning brush
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 (A). 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 (B) from case. Use care to prevent dirt and debris from falling into air lter case.
Op e r a T O r 's ma n u a l
B

5. Inspect lter element and seal. Replace lter if any of these prob­lems 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 con­ditions. 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.

Level 2.
Tools required: Air compressor and safety nozzle, or: 4 mm Hex wrench, 25 - 50 mm (1 - 2 in.) cleaning brush.
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.
Op e r a T O r 's ma n u a l
25
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 compres-
sor and safety nozzle, or;
2. Remove engine and mufer covers, and brush off dirt and debris
using the medium bristle brush.

CARBURETOR ADJUSTMENT
Engine Break-In
New engines must be operated a minimum of two tanks of fuel 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 mean sea level (MSL) (96.0 kPa and below). To maintain proper engine operation and emission compliance above 1,100 feet MSL the carburetor may need to be adjusted by an authorized ECHO service dealer.
IMPORTANT
If the engine is adjusted for operation above 1,100 feet MSL, the carburetor must be re-adjusted when operating the engine below 1,100 feet MSL, otherwise severe engine damage can result.
Op e r a T O r 's ma n u a l
27
Level 2.
Tools required: Screwdriver, Tachometer (ECHO P/N 99051130017).
Parts required: None.
1. Before adjusting carburetor clean or replace air lter and mufer,
“Spark Arrestor Screen”.
2. Make sure the cutting attachment such as hedge clipper blades or circular saw are properly adjusted. Trimmer line should be extended to cut-off knife.
3. Start engine and run several minutes to bring to operating tempera­ture. Flash choke twice during warm-up to clear any air from the fuel system.
4. Idle Speed Adjustment
• Start engine, turn “idle” speed adjustment screw clockwise
(CW) until the cutting attachment begins to turn, then turn screw out counterclockwise (CCW) until attachment stops turning. Turn screw out, CCW, an additional 1/4 turn.
WARNING
Cutting attachment must not turn or move when unit is idling.
Idle speed adjustment screw (T)
CAUTION
When starting, idling adjustment speed should be adjusted not to rotate the cutting attachment. Correct idle speed is adjusted 2300 to 2700 r/min. Or 1/4 turn CCW from the point the cutting attachment stops moving. When there is some trouble with the carburetor, refer to your dealer.

Three styles of metal blades are approved for use on the ECHO Brush Cutter. The 8-tooth blade can be sharpened during normal mainte­nance. The clearing blade and 80 tooth blade require professional service.
Before sharpening, CLOSELY inspect blade for cracks (look at the bottom of each tooth and the center mounting hole closely), missing teeth and bending. If ANY of these problems are discovered, replace the blade.
When sharpening a blade, always remove the same amount of materials from each tooth to maintain balance. A blade that is not balanced will cause unsafe handling due to vibration and can result in blade failure.
Tool required: Flat le (preferred). Electric grinder if special care is
used. Round (rat tail) le for gullet (radius).
Op e r a T O r 's ma n u a l
29
1. File each tooth at a 30 degree angle a specic number of times,
eg. 4 strokes per tooth. Work your way around the blade until all teeth are sharp.
2. DO NOT le the 'gullet' (radius) of the tooth with the at le.
The radius must remain. A sharp corner will lead to a crack and blade failure.
IMPORTANT
If an electric grinder is used, use care not to overheat teeth, do not allow tips/tooth to glow red or turn blue. DO NOT place blade in cooling water. This will change the temper of the blade and could result in blade failure.
3. After sharpening teeth, check each tooth radius for evidence of a
square (sharp) corner. Use the round (rat tail) le to renew the
radius.
