PERSONAL CONDITION AND SAFETY EQUIPMENT

WARNING DANGER

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.

4

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 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, 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.

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 unit 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.

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.

WARNING 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 ladders. Do not over reach.

Avoid Hot Surfaces

• Keep exhaust area clear of flammable debris. Avoid contact during and immediately after operation.

PERATION

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.

FUEL

Fuel Requirements

Gasoline - Use 89 Octane [R+M/2] (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

Power Blend TM Universal 2-Stroke 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 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.

Handling Fuel

WARNING 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.

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 government 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 container thoroughly before each use.

Level 2.

Tools Required: Spark Plug socket wrench and screw driver, feeler gauge

Parts Required: REPOWER TM Tune-Up Kit P/N 90074C

IMPORTANT

Use only NGK BPM-8Y spark plug (BPMR-8Y in Canada) otherwise severe engine damage may occur.

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.

3.

Adjust spark plug gap by bending outer electrode.

4.

Tighten spark plug to 150-170 kg/cm (130-150 in. lb.).

COOLING SYSTEM

Level 2.

Tools required:

Cross Head Screwdriver, 4 mm Hex Wrench,

25 or 50 mm (1 or 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.
