I lost my manual in the Sears Store in Bend, OR when I took it in to ask a question of the Salesman regarding the oil drain plug. I purchased it in 2005 and it is a 9 HP 28" Snow Thrower. I think the Model # is 831-06590. Any help in locating a new or used copy of the manual would be greatly appreciated. Please contact Ken Burke at kburke1024@aol.com
