I am looking for a york powerflex 220 fitness manuel

The York Manual for the T782 on page 10 suggests you call York directly with any questions. https://www.manualslib.com/manual/831982/York-Fitness-Platinum-T782.html?page=10#manual
I am not listing the contact numbers as this is an international outfit and the various contact details are list at the site above.

Page 14 refers to changes in speed and incline. But you are looking for more assistance. The words "calibrate" and "reset" oddly enough are not in the manual. A genteman offering common reseting proceddures offers this video: https://www.youtube.com/watch?v=PsEygAHsUf4

There is a video, but I suggest that you phone York Fitness direct and ask them. Disconnecting the power is a reset.
