PERSONAL
CONDITIONANDSAFETYEQUIPMENT
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 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.
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.
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.
Hearing Protection
ECHO recommends wearing hearing protection whenever
unit is used.
EXTENDEDOPERATION/EXTREMECONDITIONS
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.
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.

FUEL
Fuel Requirements
Gasoline - Use 89 Octane [R+M/2] (mid grade or higher) gasoline or
gasohol known to be good quality. Gasohol may contain up to 10%
Ethyl (grain) alcohol or 15% MTBE (methyl tertiary-butyl ether).
Gasohol containing methyl (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 Standards must be used. Echo brand premium
Power Blend TM Universal 2-Stroke Oil meets these standards. Engine
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.

MAINTENANCE
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 you Echo Dealer for
repairs.
SKILLLEVELS
Level 1 =Easy to do. Most required tools come with unit.
Level 2 =Moderate difficulty. Some specialized tools may be required.
Level 3 =Experience required. Specialized tools are required. ECHO recommends that
the unit be returned to your ECHO dealer for servicing.
ECHO offers REPOWERTM Maintenance Kits and Parts to make your maintenance job easier. Below each task heading
are listed the various part numbers required for that task. See your ECHO dealer for these parts.
Parts required: 90008 REPOWERTM AIR & FUEL FILTER KIT.

Level 2.
Tools required: Cross-head screwdriver, 3 and 4 mm hex wrench,
25 - 50mm (1 - 2 in.) cleaning brush
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.
GRASS TRIMMER/BRUSH CUTTER
1 . Disconnect spark plug lead from spark plug.
2 . Release stored energy in power spring by removing spark plug.
3 . Remove three (3) screws (A) from starter assembly and remove
starter.

SHARPENINGMET ALBLADES
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 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.
Fuel vapors are extremely flammable and may cause fire and/or explosion. Never test for ignition spark near an open
spark plug opening, otherwise serious personal injury may result.
