Proper clothing and safety gear must be worn when operating a trimmer/brush cutter. Physical Condition Hearing Protection 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. ECHO recommends wearing hearing protection whenever unit is used. 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. 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. 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. 5 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 WARNING DANGER Use only ECHO approved attachments. Serious injury may result from the use of a non-approved attachment combination. ECHO, INC. will not be responsible for the failure of cutting devices, attachments or accessories which have not been tested and approved by ECHO. Read and comply with all safety instructions listed in this manual and safety manual. • Check unit for loose/missing nuts, bolts, and screws. Tighten and/or replace as needed. • Inspect fuel lines, tank, and area around carburetor for fuel leaks. DO NOT operate unit if leaks are found. • Inspect shield for damage and ensure that the cut-off knife issecurely in place. Replace if either is damaged or missing. • Check that the cutting attachment is firmly attached and in safe operating condition. • Check that front loop handle and shoulder strap/ or shoulder/ waist harness are adjusted for safe, comfortable operation. See Assembly Section for proper adjustment. • Keep exhaust area clear of flammable debris. Avoid contact during and immediately after operation.

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 OPERATOR'S MANUAL 1. Disconnect spark plug lead from spark plug. 2. Remove (1) screw from top guard (A), and remove guard. B 3. Remove (3) screws from engine cover (B), and remove cover. 4. Use the brush to remove dirt form cylinder fins. A 5. Remove grass and leaves from the grid between the recoil starter and fuel tank. 6.

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. C B A GRASS TRIMMER/BRUSH CUTTER OPERATOR'S MANUAL CARBURETOR ADJUSTMENT Engine Break-In New engines must be operated for a minimum of two tanks of fuel 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. Idle Speed Adjustment Idle speed adjustment may be required periodically to comply with specifications for this unit. See page 11, "Specifications," for correct idle speed. A Level 2.

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.
