Verify the key is inserted and turned to the "On" position. Press the primer button twice to start the engine if the engine won't start. Move the snow thrower into a warm garage if you suspect the engine has frozen. Engines can freeze if you leave the Snapper outside in sub-zero temperatures. Use the choke to start cold engines.
Adjust the auger control cable if the auger does not stop within five seconds of the control lever being released. Turn the engine off and take the key out. Slide the auger cable cover upwards exposing the cable adjustment loops. You will see a Z-like bend; disengage it and engage it in the next highest loop and the tension will be increased. Slide the cover back and try the Snapper again.
Repeat the previous step if the Snapper snow blower won't discharge snow. If the Snapper still does not discharge snow, the discharge chute may be clogged. Stop the engine and remove the key. Use a piece of wood to clean the chute and auger housing. Look for any foreign object that may have been picked up and remove it.
