I am currently setting up a CM-56 and am without a manual. I require electrical diagrams as well as technical information relating to the machine. If anyone has any information or is familiar with this machine, their input would greatly be appreciated.

One of the problems I find myself facing with this machine is the fact that the knurled drive wheels do not seem to provide enough drive and end up slipping leading to both wear on the wheel and on the drive track(a piece of angle-iron). If anyone has retrofit this type of machine with a better drive system, I would like to hear about the way in which this design was improved(it's not that hard to improve such a fragile system).

As well if anyone has any leads on where I might find a CM-56 manual, I would appreciate it.
