How do I use the electric starter on models that have one?

Plug an extension cord rated for 15 amps at 125 volts into the outlet on the engine's surface, then plug the other end into a grounded three-prong 120-volt AC outlet. Insert the ignition key, set the choke to CHOKE, press the primer 3 times, and then push the starter button to start the engine. When disconnecting, always unplug the wall outlet end of the extension cord first before unplugging from the snow blower. (Page 11)
