Frister and Rossman Cub 4 Service Manual?

I have the instruction manual, that's not the problem. The motor is smoking and my beautiful Frister and Rossman Cub 4 will not work. I need the SERVICE manual. I also need a PARTS manual. I really do not want to buy a new machine - this Frister and Rossman Cub 4 is strong, sturdy, robust, well built - but the motor smokes! Help!
