SAFETY INSTRUCTIONS
PERSONAL
Trimmer/Brush Cutter users risk injury to themselves and others if the trimmer/brush cutter is used improperly and or safety precautions are not followed. Proper clothing and safety gear must be worn when operating a trimmer.
CONDITION AND SAFETY EQUIPMENT
W ARNING DANGER
5
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.
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.
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.
Wear sturdy work shoes with non-skid 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.
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.
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

Fuel Requirements
Gasoline - Use 89 Octane [ ] (mid grade or higher) gasoline known to be good quality. Gasoline may contain up to 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 50:1 oil meets these standards. Engine problems due to inadequate lubrication caused by failure to use an ISO-L-EGD and J.A.S.O. FC certified oil, such as Echo Premium 50:1 Two-stroke Oil, 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 EPA Emission Defect Warranty Explanation.)
IMPORTANT
Echo Premium 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 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.

Handling Fuel
W ARNING DANGER
Fuel is VERY flammable. Use extreme care when mixing, storing or handling, otherwise 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 capsslowly 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
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.
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.
IMPORTANT
Stored two-stroke fuel may separate. ALWAYS shake fuel container thoroughly before each use.

damage. If element is fuel soaked and very dirty, replace.
OPERATOR'S MANUAL
21
3 . If element can be cleaned and reused, be certain it:
-still fits the cavity in the air cleaner cover.
-is installed with the original side out.
FUEL FILTER
Level 1.
Tools required: Fuel line hook, 200 - 250 mm (8 - 10 in.) length of wire
with one end bent into a hook. Clean rag, funnel, and an approved fuel container.
Parts required: 90030 REPOWERTM AIR & FUEL FILTER KIT.
W ARNING DANGER
Fuel is VERY flammable. Use extreme care when mixing, storing or handling.
1 . Use a clean rag to remove loose dirt from around fuel cap and
empty fuel tank.

driver supplied with unit), Feeler gauge, preferably a wire gauge, Soft Metal Brush.
Parts Required: REPOWERTM TUNE-UP KIT 90065
1 . Remove spark plug and check for fouling, worn and rounded
center electrode.
2 . Clean the plug or replace with a new one. DO NOT sand blast to
clean. Remaining sand will damage engine.

COOLING SYSTEMS CLEANING
Level 2.
Tools required: Cross Head Screwdriver, 4 mm Hex Wrench, Cleaning
Brush, 25 - 50 mm (1 - 2 in.) medium bristle paint 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.
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.
1 . Remove spark plug lead.

GRASS TRIMMER/BRUSH CUTTER
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 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.
8-tooth Blade
Tool required: Flat file (preferred). Electric grinder if special care is
used. Round (rat tail) file for gullet (radius).
OPERATOR'S MANUAL
27
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.
