Tips: Label Screws by guide step number and size as you go. That way you can easily backtrack and any divergences between your machine's screws and the guide's will be a non-issue.

Also, be careful when removing and tightening screws. I stripped one of my screws and almost needed to call in the pros.

Use common sense throughout your fix. Nothing should be forced. Take breaks and return with a clear head.

Good luck!
