Compare the illustrations with your unit to familiarize yourself with the location of the various controls and adjustments. Save this manual for future reference. MULCHING BLADES Your blower is equipped with mulching blades as a standard feature. When using the optional vacuum attachment, the mulching blades automatically reduce debris at a ratio of up to 16:1. Upper Lower Vacuum T_ Vacuum Tube Throttle Lever Primer Button Choke Lever Fuel Mix Elbow Tube Blower Tube \ Rope Rear Handle THROTTLE LEVER The THROTFLE LEVER is used to select the desired engine speed and to stop the engine. Move the throttle lever to the position for full speed operation. Move the throttle lever to the _ posi- tion for idle speed. To stop the engine, move the throttle lever to the STOP posi- tion. PRIMER BUTTON The PRIMER BUqq-ONremoves air from the carburetor and fuel lines and fills them with fuel. This allows you to start the engine with fewer pulls on the starter rope. Activate primer button by pressing it and allowing it to return to its original position. CHOKE LEVER The CHOKE helps to supply fuel to the engine to aid in cold starting. Activate the choke by moving the choke lever to the FULL CHOKE position. After engine attempts to start, move the choke lever to the HALF CHOKE position. Once en- gine starts, move choke lever to the RUN position. -6-

or blowing debris, hold the unit with the muffler side fac- ing away from your body and clothes (see OPERATING POSITION). • To reduce the risk of hearing loss associated with sound level(s), hear- ing 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 rea- sonable hours-not early in the morn- ing or late at night when people might be disturbed. Comply with times listed in local ordinances. Usual recommen- dations are 9:00 a.m. to 5:00 p.m., Monday though Saturday. • To reduce noise levels, limit the num- ber of pieces of equipment used at any one time. • To reduce noise levels, operate pow- er 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 blow- ers 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 equip- ment, CLEAN UP! Dispose of debris in trash receptacles. OPERATING POSITION Protection Blower Vacuum BEFORE STARTING ENGINE _WARNING: 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 _WARNING: 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 en- gine 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 relat- ing to fuel before fueling your unit. IMPORTANT Experience indicates that alcohol blended fuels (called gasohol or using ethanol or methanol) can attract mois- ture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel sys- tem 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 clean- er products in the fuel tank or perma- nent damage may occur. Fuel stabilizer is an acceptable alter- native 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. -7-

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, ani- mals, glass, and solid objects. Blower \ Vacuum A WARNING: When starting engine, hold the unit as illustrated. Do not set unit on any surface except a clean, hard area when starting engine or while en- gine is running. Debris such as gravel, sand, dust, grass, etc. could be picked up by the air intake and thrown out through the discharge opening, damag- ing the unit or property, or causing seri- ous injury to bystanders or the operator. STARTING A COLD ENGINE (or a warm engine after running out of fuel) 1. Move the throttle lever to the '1_ position. 2. Move the choke lever to the FULL CHOKE position. 3.

If you require further assis- tance or are unsure about performing this procedure, call our customer as- sistance help line at 1-800-235-5878. Old fuel, a dirty air filter, a dirty fuel fil- ter, or flooding may give the impres- sion of an improperly adjusted carbu- retor. Check these conditions before adjusting the carburetor. The carburetor has been carefully set at the factory. Adjustments may be necessary if you notice any of the fol- lowing conditions: • Engine will not idle. See LOW SPEED MIXTURE ADJUSTMENT (L) under ad- justing procedure. • Engine dies or hesitates instead of ac- celerating. See ACCELERATION CHECK under adjusting procedure. • Loss of power. See MIXTURE ADJUST- MENT (L or H) under adjusting proce- dure. There are two adjustment screws on the carburetor. The low speed adjust- ment screw is marked with the letter L, and the high speed adjustment screw is marked with the letter H. The throttle lever is used to control engine speed. The throttle lever can be placed in one of four positions: STOP, IDLE or "_1_, FULLTHROTTLE or '_, and one inter- mittent position. _imer Button Thro_.
