Proper Clothing  
Physical Condition  
Wear snug fitting, durable clothing;  
• Pants should have long legs, shirts with long sleeves.  
• DO NOT WEAR SHORTS,  
Your judgment and physical dexterity may not be good:  
• if you are tired or sick,  
• if you are taking medication,  
• DO NOT WEAR TIES, SCARVES, JEWELRY,  
or clothing with loose or hanging items that could  
become entangled in moving parts or surrounding  
growth..  
• 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.  
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.  
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.  
Hot Humid Weather  
Hearing Protection  
ECHO recommends wearing hearing protection whenever  
unit is used.  
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 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 informa-  
tion, ECHO does not recommend the use of ECHO products by anyone who has a pacemaker.  
Extended Operation/Extreme Conditions  
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 sensa-  
tions, 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 exer-  
cises during frequent work breaks, and also by not smoking.  
• Limit the hours of operation. Try to fill each day with jobs where op-  
erating the unit or other hand-held power equipment is not required.  
• If you experience discomfort, redness, and swelling of the fingers fol-  
lowed by whitening and loss of feeling, consult your physician before  
further exposing yourself to cold and vibration.

Repetitive Stress Injuries  
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 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 fingers, 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  
fingers 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 flammable debris. Avoid contact during  
and immediately after operation.

NOTE  
The Barrier Bar is used to restrict rearward movement of the unit. The Barrier Bar is NOT A HANDLE and should  
not be gripped when using or carrying the unit.  
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.  
80 Tooth brush blade is designed for cutting brush and woody growth  
up to 13mm (1/2 in.) diameter.

up to 64 mm (2-1/2 in.) diameter.  
Use Shoulder/Waist harness Use of the Shoulder/Waist Harness is  
recommended for ALL Trimmer/Brush Cutter use, not just Blade oper-  
ation. 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 move-  
ment.  
NOTE  
In case of Emergency, pull up on the Quick Release Collar to dis-  
connect the trimmer from the harness.

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 alco-  
hol) 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  
inadequate lubrication caused by failure to use an ISO-L-EGD (ISO/CD 13738) and J.A.S.O. FD certified oil, such as  
Echo premium Power Blend X TM, will void the two-stroke engine warranty. (Emission related parts only are covered for  
two years, regardless of two-stroke oil used, per the statement listed in the Emission Defect Warranty Explanation.)  
IMPORTANT  
Echo premium Power Blend X 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 specified in those manuals.

Handling Fuel  
DANGER  
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 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 flames.  
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.

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 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.

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.  
A
1. Check idle speed and reset if necessary. If a tachometer is avail-  
able, idle speed screw (A) should be set to the specifications found  
on "Specifications" 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 cutting attachment  
should not turn at idle, otherwise serious personal injury may  
result.

sharpenIng metal blades  
Three styles of metal blades are approved for use on the ECHO Brush  
Cutter. The 8-tooth blade can be sharpened during normal mainte-  
nance. 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:  
Flatle(preferred). Electricgrinderifspecialcareis  
used. Round (rat tail) file for gullet (radius).  
1. File each tooth at a 30 degree angle a specific number of times,  
eg. 4 strokes per tooth. Work your way around the blade until  
all teeth are sharp.  
2. DO NOT file the 'gullet' (radius) of the tooth with the flat file.  
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) file to renew the  
radius.
