SM 74 side guide motor and potentiometer replacement.

Hello
We have to replace a motor and potentiometer. Is the a specific way to do this or can I get directions to an install sheet for both?

 

Hi sir:
Normally heidelberg, provide Instruction with electrical/electronic parts.
However, there are another, that they suggest to call the Service Heidelberg.
If you feel with the instruction provided , you can Do it yourself, proceed.
Otherwise look for help.
