PERSONAL
CONDITION AND SAFETY EQUIPMENT
W ARNING DANGER
Trimmer/Brush Cutter users risk injury to themselves and others if the trimmer/brush cutter is used improperly
or safety precautions are not followed. Proper clothing and safety gear must be worn when operating a
trimmer/brush cutter.
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 trimmer.
Hand Protection
Wear no-slip, heavy duty work gloves to improve your
grip on the Trimmer/Brush Cutter handles. 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 fitting, durable clothing;
• Pants should have long legs, shirts with long
sleeves.
• DO NOT WEAR SHORTS,
• DO NOT WEAR TIES, SCARVES, JEWELRY.
Wear sturdy work shoes with non-skid soles;
• DO NOT WEAR OPEN TOED SHOES,
• DO NOT OPERATE UNIT BAREFOOTED.
EXTENDED OPERATION/EXTREME CONDITIONS
Vibration and Cold
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 sensations, 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
exercises during frequent work breaks, and also by not smoking.
• Limit the hours of operation. Try to fill 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 fingers
followed by whitening and loss of feeling, consult your physician
before further exposing yourself to cold and vibration.
Page 6

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
movement.
• 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 fingers, hands, wrists, or
arms. The sooner RSI/CTS is diagnosed, the more likely permanent
nerve and muscle damage can be prevented.
EQUIPMENT
W ARNING DANGER
Use only ECHO approved attachments. Serious injury may result from the use of a non-approved attachment
combination. ECHO, INC. will not be responsible for the failure of cutting devices, attachments or accessories which
have not been tested and approved by ECHO. Read and comply with all safety instructions listed in this manual and
safety manual.
• Check unit for loose/missing nuts, bolts, and screws. Tighten and/or
replace as needed.
• Inspect fuel lines, tank, and area around carburetor for fuel leaks. DO
NOT operate unit if leaks are found.
• Inspect shield for damage and ensure that the cut-off knife issecurely
in place. Replace if either is damaged or missing.
• Check that the cutting attachment is firmly attached and in safe
operating condition.
• Check that front handle and shoulder strap/ or shoulder/waist
harness are adjusted for safe, comfortable operation. See Assembly
Section for proper adjustment.
• Keep exhaust area clear of flammable debris. Avoid contact during
and immediately after operation.

BLADE SELECTION
WARNING DANGER
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.
Page 17
GRASS TRIMMER/BRUSH CUTTER
Plastic/Nylon 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 (P/N 69600120331) 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.
OPERATOR'S MANUAL
17
80 Tooth Brush Blade (P/N 69500120331) is designed for cutting brush
and woody growth up to 64 mm (2-1/2 in.) diameter.
22 Tooth Clearing Blade (99944200130) is designed for dense thickets
and saplings up to 64 mm (2-1/2 in.) diameter.
Use Shoulder/Waist Harness (P/N 99944200200) 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.
NOTE
In case of Emergency, pull up on the Quick Release Collar to
disconnect the trimmer from the harness.

problems due to inadequate lubrication caused by failure to use an ISOL-EGD and J.A.S.O. FC certified oil, such as Echo premium Power Blend
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 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.
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 and remix.
5 . Install fuel container cap and wipe any spilled fuel from container
and surrounding area.
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. Contact your ECHO dealer for
ordering information.
After refueling
• Wipe any spilled fuel from the unit.
• Move at least 3 m (10 ft.) from refueling
location before starting the engine.
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 government for the laws affecting
your area. As a precaution, store fuel in an
approved, air tight container. Store in a well
ventilated, unoccupied building, away from
sparks and flames. Do not store fuel longer
than 30 days.
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.
Handling Fuel
W ARNING 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!
• NEVER refuel a unit with the engine running.
• DO NOT fill fuel tanks indoors. ALWAYS fill fuel tanks outdoors
over bare ground.
• Securely tighten fuel cap after refueling.
• Inspect for fuel leakage. If fuel leakage is found, do not start or
operate unit until leakage is repaired.
IMPORTANT
Stored two-stroke fuel may separate.
ALWAYS shake fuel container thoroughly before each use.

COOLING SYSTEMS CLEANING
Level 2.
Tools required: 4 mm Hex Wrench, Cleaning Brush 25 or 50 mm
(1 or 2 in.)
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.
0.65 mm
(0.026 in.)
Removal of cooling passage blockages or cleaning of cooling fins is
considered “Normal Maintenance”. Any failure attributed to lack of
maintenance is not warranted.

SHARPENING MET AL BLADES
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.
B
A
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 file (preferred). Electric grinder if special care is
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.
