Once engine starts, move choke lever to the RUN position. PRIMER BUTTON The PRIMER BU-i-ION removes air _om the carburetor and fuel lines and fills them with fuel. This allows you to start -6- OPERATING TIPS • While vacuuming or blowing debris, hold the unit with the muffler side facing away from your body and clothes (see OPERATING POSITION). • To reduce the risk of hearing loss associated with sound level(s), hearing protection is required. • To reduce the risk of injury associated with contacting rotating parts, stop the engine before installing or removing attachments. Do not operate without guard(s) in place. • Operate power equipment only at reasonable hours-not early in the morning or late at night when people might be disturbed. Comply with times listed in local ordinances. Usual recommendations are 9:00 a.m. to 5:00 p.m., Monday though Saturday. • To reduce noise levels, limit the number of pieces of equipment used at any one time. • To reduce noise levels, operate power blowers at the lowest possible throttle speed to do the job. • Use rakes and brooms to loosen debris before blowing. • In dusty conditions, slightly dampen surfaces or use a mister attachment when water is available. • Conserve water by using power blowers instead of hoses for many lawn and garden applications, including areas such as gutters, screens, patios, grills, porches, and gardens. • Watch out for children, pets, open windows, or freshly washed cars. Blow debris away safely. • Use the full blower nozzle extension so the air stream can work close to the ground. • After using blowers and other equipment, CLEAN UP! Dispose of debris in trash receptacles. OPERATING POSITION Protection I Blower Vacuum BEFORE STARTING '_LWARNING: ENGINE Be sure to read the fuel information in the safety rules before you begin. If you do not understand the safety rules, do not attempt to fuel your unit. Call 1-800-235-5878. FUELING ENGINE ,_LWARNING: Remove fuel cap slowly when refueling. This engine is certified to operate on unleaded gasoline. Before operation, gasoline must be mixed with a good quality 2-cycle air-cooled engine oil. We recommend Craftsman brand oil. Mix gasoline and oil at a ratio of 40:1 (A 40:1 ratio is obtained by mixing 3.2 ounces of oil with 1 gallon of unleaded gasoline). DO NOT USE automotive oil or boat oil. These oils will cause engine damage. When mixing fuel, follow instructions printed on container. Once oil is added to gasoline, shake container momentarily to assure that the fuel is thoroughly mixed. Always read and follow the safety rules relating to fuel before fueling your unit. IMPORTANT Experience indicates that alcohol blended fuels (called gasohol or using ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system of an engine while in storage. To avoid engine problems, empty the fuel system before storage for 30 days or longer. Drain the gas tank, start the engine and let it run until the fuel lines and carburetor are empty. Use fresh fuel next season. Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur. Fuel stabilizer is an acceptable alternative in minimizing the formation of fuel gum deposits during storage. Craftsman brand oil is already blended with fuel stabilizer. See the STORAGE section for additional information. STOPPING YOUR ENGINE • To stop the engine, move the throttle lever to the STOP position. STARTING THEENGINE _LWARNING: You MUST make sure the tubes are secure before using the unit. • Fuel engine. Move at least 10 feet (3 meters) away from the fueling site. • Hold the unit in the starting position as shown. Make sure the blower end is directed away from people, animals, glass, and solid objects. .,_i@__p STARTING POSITION Blower Vacuum ,_ WARNING: When starting engine, hold the unit as illustrated.
