Proper clothing and safety gear must be worn when operating a blower.

• 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 recom- mended, 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 physi- cian before further exposing yourself to cold and vibration.

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 pre- vented. 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. • 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.

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. uel to O li Mix - 50:1 Ra it o F U.S. ETRIC M GAS O LI GAS LI O ns olla G F .l o .z tiL er .c c 1 2 5 2.6 5.2 3 1 4 8 0 2 80 160 00 4 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. 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. • 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. 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, close fuel container, and remix. IMPORTANT Stored two-stroke fuel may separate. ALWAYS shake fuel container thoroughly before each use.

and take all safety precautions or serious personal injury may result. Do not point the blower pipe in the direction of people or pets. Read the Safety Section on pages 4 - 6 carefully. IMPORTANT To avoid engine damage due to over-revving, do not block blower pipe opening. 1. Use only during appropriate hours. 2. Allow the engine to warm up at a fast idle for a few minutes. 3. Set engine speed with throttle lever (A). 4. Use lower speed to blow dry leaves from walks, patios and drives. 5. Additional speed may be necessary to clean grass and leaves from a lawn or flower bed. 6. Higher speed may be necessary to move gravel, dirt, snow, bottles or cans from a driveway, street, parking lot or stadium. NOTE Never use a higher speed setting than necessary to perform a task. Remember, the higher the engine speed, the louder the blower noise. Minimize dust by using blower at lower speeds and by dampening material with water/mist when necessary. Keep debris on your property. Be Smart - be a good neighbor. A PB-651H PB-651T A

Level 2. Tools required: 25 - 50mm (1 - 2 in.) cleaning brush, Cross Head Screwdriver 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. Cleaning Grill 1. Remove accumulated debris from intake grill between backpack frame and blower housing. Cleaning Cylinder Fins 1. Remove spark plug and engine cover (four screws), pull cover away from engine. 2. Clean cylinder fins (A) to allow cooling air to pass freely. 3. Install engine cover and spark plug. SPARK PLUG Level 1. Tools required: 19mm Spark Plug deep socket, Feeler gauge Parts Required: RepowerTM Tune Up Kit P/N 90070 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.). A 0.65 mm (0.026 in.)

Level 2. Tools required: Cross Head Screwdriver Parts Required: Spark arrestor screen P/N A310000000, Gaskets P/N V104000550, V104000560 WARNING DANGER Do not perform maintenance on engine or muffler until engine and muffler are completely cool, otherwise serious personal injury may result. IMPORTANT Carbon deposits in muffler will cause a drop in engine output and overheating. Spark arrestor screen must be checked periodically. 1. Remove spark plug and engine cover (four screws). 2. Remove spark arrestor covers (A), gaskets (B), and spark arrestor screen (C) from muffler. Replace screen if plugged with carbon deposits. NOTE When cleaning carbon deposit, be careful not to damage the catalytic element inside muffler. 3. Install spark arrestor screen and cover. 4. Install spark plug and engine cover. Cylinder Exhaust Port Level 3. IMPORTANT The cylinder exhaust port must be inspected and cleaned of excess carbon every 3 months or 90 hours of operation in order to maintain this engine within the emissions durability period. ECHO strongly recommends that you return your unit to your ECHO dealer for this important maintenance service. A B C

break-in before carburetor adjustments can be made. During the break-in period your engine performance will increase and exhaust emissions will stabilize. Idle speed can be adjusted as required. High Altitude Adjustment High altitude adjustment is not required for proper operation of this engine. Level 2. Tools required: Screwdriver, tachometer (Echo P/N 99051130017) Parts required: None.
