PERSONAL CONDITION AND SAFETY EQUIPMENT

W ARNING DANGER

Power Blower users risk injury to themselves and others if the power blower is used improperly or safety precautions are not followed. Proper clothing and safety gear must be worn when operating a blower.

"Run"

Position

Page 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 blower handle. Gloves also reduce the transmission of machine vibration to your hands.

Breathing Protection

Wear a facemask to protect against dust.

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, and JEWELRY.

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 blower 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.

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.

OPERATOR'S MANUAL

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.

W ARNING 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.

• Take wind conditions into account: avoid open doors and windows.

• Do not point blower at people or animals.

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.

OPERATION

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

W ARNING

Alternative fuels, such as E-20 (20% 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 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 twostroke 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

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 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.

• Move at least 3m (10 ft.) from refueling location before starting the engine.

POWER BLOWER

OPERATOR'S MANUAL

2 . Remove air filter cover. Brush dirt from inside cover and away from

edges of air filter. 3 . Check air filter seal for tight fit with air filter case. 4 . Remove air filter from case. Use care to prevent dirt and debris

from falling into air filter case. 5 . Inspect filter element and seal. Replace filter if any of these

problems are present:

•Air filter seal does not fit tightly against case

•Air filter seal is distorted, worn, or damaged

•Air filter element has holes or other damage

•Air filter element is saturated with dirt

•Air filter element is soaked with fuel mix

6 . If air filter is in good condition and can be cleaned and reused,

lightly brush debris from air filter element, or blow filter element

clean using low pressure (40 psi or less) compressed air directed at

inside of filter.

IMPORTANT

When using compressed air, always direct air stream at inside surface of filter so dust and debris will be blown out of filter. Keep air nozzle 6 - 8 inches away from filter to prevent damage to filter.

7 . Install air filter in case, and replace cover.

NOTICE

Actual replacement interval for air filter depends on operating conditions. Operation in dustier applications requires more frequent cleaning and replacement.

COOLING

Level 2.

Tools required: 25 - 50 mm (1 - 2 in.) Cleaning brush, cross head

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.

SYSTEMS CLEANING

screwdriver

Cleaning Grill

1 . Remove accumulated debris from intake grill (A) between back-

pack frame and blower housing.

Cleaning Cylinder Fins

1 . Remove engine cover (five screws), pull cover away from engine.

Clean cylinder fins (B) to allow cooling air to pass freely.

1 . With engine off, turn HI speed screw (C) counterclockwise to

stop.

2 . Turn LO speed screw (B) midway between stops.

3 . Turn idle screw (A) until tip of screw just touches throttle plate;

then turn three (3) turns clockwise.

Final Adjustment

IMPORTANT

Limiter caps prevent exceeding emission limits and over rich adjustment, but not over lean adjustment, which can cause engine failure: Do not exceed recommended HI speed engine R.P.M. during operation, or for long periods during adjustment.

1 . Start engine, run at idle for one minute.

2 . Complete warm up by running at full throttle for 5 minutes,

operating choke twice to clear air from carburetor chambers.

3 . Run at idle and accelerate to check for smooth transition from idle

to high speed; if engine hesitates, turn LO speed screw (B) counterclockwise 1/8th of a turn at a time until acceleration is smooth.

4. Use a tachometer to adjust idle speed to specifications found on page 23.
