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 ma-
chine vibration to your hands.
Hearing Protection
ECHO recommends wearing hearing protection whenever unit is used.
Proper Clothing
Wear snug fitting, 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 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
• Always use both hands on the handles. Do not operate one-handed.
Always hold the unit with the fingers and thumbs 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.

ness, 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 fires. is unit is equipped with a spark arrestor to
prevent 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 fire authorities for laws or regulations regarding fire prevention require-
ments.
BLADE SELECTION
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

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 Grass and Weed Blade is designed for grass, garden debris and
thick weeds up to 19 mm (3/4”) diameter. DO NOT use this blade for
brush or heavy woody growth.
80 Tooth Brush Blade is designed for cutting brush and woody growth
up to 13 mm (1/2 in.) diameter.
22 Tooth Clearing Blade is designed for dense thickets and saplings
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
WARNING
In case of emergency, pull the quick release latch to disconnect
the trimmer from the harness.

FUEL
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-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
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 XTM 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 certified oil, such
as ECHO premium Power Blend XTM, will void the two-stroke engine warranty.
IMPORTANT
ECHO premium Power Blend XTM 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.

COOLING SYSTEM
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 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.
• Dustanddebrisbuild-upontheoutsideofthecylinder.Thisbuild-up
insulates the engine and prevents the heat from leaving.
Removal of cooling passage blockages and cleaning of cooling fins is
considered “Normal Maintenance.” Any failure attributed to lack of
maintenance is not warranted.
1. Periodically blow dirt and debris off cooling fins with a compres-
sor and safety nozzle, or;
2. Remove engine and muffler 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 1100
feet above sea level (ASL) (96.0 kPa). To maintain proper engine operation and emission compliance above 1100 feet
ASL the carburetor may need to be adjusted by an authorized ECHO service dealer.
IMPORTANT
If the engine is adjusted for operation above 1100 feet ASL, the
carburetor must be re-adjusted when operating the engine below
1100 feet ASL, otherwise severe engine damage may result.
Level 2.
Tools required: Screwdriver, Tachometer (ECHO P/N 99051130017).
Parts required: None.
1. Before adjusting carburetor clean or replace air filter and muffler,
“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 tempera-
Idle speed adjustment screw (T)
ture. 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.
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.
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.

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:
Flatfile(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.
