Our company just picked up an older Baumfolder DC500 folder (with right-angle attachment) but it did not have a user manual with it. Trying to find a PDF of that model's manual online is like trying to solve the problem of world peace. Anyone here have any suggestions on where I could look online to find an electronic copy of the user manual? Doesn't have to be a free download... we'd be willing to pay an online manual clearinghouse site for a copy.
