Here's a listing for one that sold on E-Bay with that number on it (90 823265). Says it's from 1992 - 1994.
I also saw a manual on ebay that had no dates with same number, so I was not sure if that number (90 823265) covered all of the older model 40 Force. Thanks for your quick response. I know I have an older model, but not sure on the year. I have a broken ankle so it is too hard to go and check serial number. Was hoping that the manual would fit all of the older manuals.
