1. Dual Wheel Drive--For heavy snow, insert the kwik pins into the wheel hubs for power drive to both wheels. See figure 20A. Caution: Experience indicates that alcohol blended fuels (called gasohol or using ethanol or methanol) can attract moisture which leads to separation and forma- tion of acids during storage. Acidic gas can damage the fuel system of an engine while in storage. To avoid engine problems, the fuel system should be emptied 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. See Storage section of this manual for additional infor- mation. 2.
Single Wheel Drive--Remove the kwik pin from the wheel hub on one side of the unit, and place in the outside hole in the axle. See figure 20B. This posi- tion allows power drive to one wheel only, making the unit easier to maneuver during transport. If traction while throwing snow becomes a problem, place kwik pin in Dual Wheel Drive position. Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur. Never fill fuel tank indoors, when engine is running or while engine is still hot. Never fill fuel tank completely. Fill tank to within 1/4 to 1/2 inch from the top to provide space for expansion of fuel. Wipe up any spilled fuel before starting engine.
Store gasoline in a clean, approved container. Dual Wheel Drive Single Wheel Drive . Make certain the spark plug is tightened securely into engine, and spark plug wire is attached to spark plug. If torque wrench is available, torque plug to between 18 and 23 foot pounds. FIGURE 20. TO SERVICE ENGINE The engine on this snow thrower was shipped without oil in the crankcase. Oil must be added before engine is started. TO START ENGINE 1. Position snow thrower so engine is level. Remove oil fill cap and dipstick. See figure 21. Fill crankcase to FULL mark on dipstick (about 1-1/2 pints) with SAE 10W30 motor oil or equivalent. Do not overfill.
Tighten fill cap and dipstick securely each time you check oil level. If temperature is con- sistently 20°F. or lower, SAE 5W30 motor oil may be substituted. 1. Make certain the auger and traction drive clutch levers are in the disengaged (released) position. 2. Move throttle control up to FAST postion. Insert ig- nition key into slot. See figure 22. Be certain it snaps into place. Do not turn key, 3. Rotate choke knob to FULL choke position (cold engine start). If engine is warm, place choke in OFF position in- stead of FULL. 2. Fill fuel tank with clean, fresh, lead-free grade automotive gasoline. 4. Push primer button two or three times. See figure 22.
If engine is warm, push primer button once only. Oil Cap/ Fuel Dipstick._ Fill_ _)_ NOTE Always cover vent hole in primer button with finger while pushing. Additional priming may be necessary for the first start if temperature is below 15°F. _rliili O (_ _ NOTE: Oil level must be between full and add mark 5.
