Even the repair shops won't repair a plastic machine and there are no manuals or parts available for them.
I should expand on the above. Some shops will clean and oil the PGM (Plastic Garbage Machine) if there are repairs they likely won't get repaired because the repairs can cost more than the machine originally cost. There are manuals if you are a 'dealer' for that company. It is very expensive to become a dealer. The dealer has the manual to do the repairs at a great expense of operating a franchise - they have to pass that along to the customer - high priced repairs so the customer isn't going to spend more than she spent on the machine when it was new.
