Remove the ignition key when the snow thrower is not in use. See Figure 14. IMPORTANT: Do NOT attempt to turn the key. Skid Shoe The position of the skid shoe is determined by the condition of the ground from where snow has to be removed. See Figure 14. Throttle Control The throttle control is located on the engine. It regulates the speed of the engine and will shut off the engine when pushed down completely. See Figure 14 SECTION 5: OPERATING YOUR SNOW THROWER Before Starting WARNING: Read, understand, and follow all instructions and warnings on the machine and in this manual before operating. Gas & Oil Fill-Up Service the engine with gasoline and oil as instructed in the separate engine manual packed with your snow thrower. Read instructions carefully. WARNING: Use extreme care when handling gasoline. Gasoline is extremely flammable and the vapors are explosive. Never fuel the machine indoors or while the engine is hot or running. Extinguish cigarettes, cigars, pipes and other sources of ignition. • A plastic cup is provided inside the fuel fill opening on the fuel tank. Remove and discard this cup before filling up the tank. Use the separate fuel tank cap to close after fill-up. To Start Engine • Attach spark plug wire to spark plug. Make certain the metal loop on the end of the spark plug wire (inside the boot) is fastened securely over the metal tip on the spark plug. • Make certain the auger and drive clutch levers are in the disengaged (released) position. • Move throttle control up to FAST position. Insert ignition key into slot. Make sure it snaps into place. Do not turn key. NOTE: Engine will not start unless ignition key is inserted into ignition slot in carburetor cover. Electric Starter (If Equipped) • Determine that your house wiring is a three-wire grounded system. Ask a licensed electrician if you are not certain. • If your house wiring system is not a three-wire grounded system, do not use this electric starter under any conditions. WARNING: The optional electric starter is equipped with a grounded three-wire power cord and plug, and is designed to operate on 120 volt AC household current. It must be used with a properly grounded three-prong receptacle at all times to avoid the possibility of electric shock. Follow all instructions carefully prior to operating the electric starter. • If your home electrical system is grounded, but a three-hole receptacle is not available, one should be installed by a licensed electrician before using the electric starter. • If you have a grounded three-prong receptacle, proceed as follows. • Rotate choke knob to OFF position and do not prime engine. • Connect power cord to switch box on engine. Plug the other end of power cord into a three-prong 120volt, grounded, AC receptacle. • Push starter button to crank engine. As you crank the engine, move choke knob to FULL choke position. • When engine starts, release starter button and move choke gradually to OFF. If engine falters, move choke immediately to FULL and then gradually to OFF. • When disconnecting the power cord, always unplug from the three-prong receptacle first and then from the snow thrower. Recoil Starter • Rotate choke knob to FULL choke position (cold engine start). If engine is warm, place choke in OFF position instead of FULL. • Push primer button two or three times for cold engine start. If engine is warm, push primer button only once. NOTE: Always cover vent hole in primer button when 11 pushing. Additional priming may be necessary for first start if temperature is below 15 degrees Fahrenheit. • Grasp starter handle and pull rope out slowly, until it pulls slightly harder. Let rope rewind slowly. • Pull starter handle rapidly. Do not allow handle to snap back. Allow it to rewind slowly while keeping a firm hold on the starter handle. • As engine warms up and begins to operate evenly, rotate choke knob slowly to OFF position. If engine falters, return to FULL choke, then slowly move to OFF position. To Stop Engine • Run engine for a few minutes before stopping to help dry off any moisture on the engine. • To help prevent possible freeze-up of starter, proceed as follows. Electric Starter (If equipped) • Connect power cord to switch box on engine, then to 120 volt AC receptacle. With the engine running, push starter button and spin the starter for several seconds. The unusual sound made by spinning the starter will not harm engine or starter. Disconnect the power cord from receptacle first, and then from switch box. Recoil Starter • With engine running, pull starter rope with a rapid, continuous full arm stroke three or four times. Pulling the...
