I inherited a RIDGID/KOLLMANN K-26 drain cleaner. I don't have any directions with it. I checked for youtube videos but haven't found one for this model. I'm not sure if its broken as the snake does not extend or retract if I spin it. Can anybody help? Thank You. P.S. Am I supposed to pull the snake out manually, tighten it so the handle will rotate it, and pull the snake back manually?
