Can you post a picture yet? Sometimes you have to have a minimum of 5 posts.....Sometimes. A 1402 is an older machine for sure. 136 Hmmmm Very old indeed. early to mid 60s I would say. You may beable to find a manual from Peterson Equipment in Salt Lake City Utah. Bill Guthrie at Snow Trans in Idaho, Possibly Saftey One in Sedalia Colorado or from a fellow member Brad (BOGGIE) at Minnesota outdoor Sports in Brainerd Minessota. PM BOGGIE first. He is most likely the quickest to get you anything. POST PICS PLEASE!
