I have the rator 50 v2, and I did have a few problems with the manual, mostly because it's exploded view, and doesn't always clearly show how the parts go together. If you have this problem, just look ahead in the manual. The current step is exploded view, but whatever you are attaching the current step to, they will show the assembled machine from previous steps. So, once I figured out to occasionally look ahead to compare what I was doing to the finished pictures, I didn't have a problem. Biggest thing is to take your time, and PAY ATTENTION!!!!! Items like the thrust bearings are easy to get turned around if you're not careful.[X(]
Most of the parts are bagged in steps, but some parts are in other bags, so look around before you think you're missing something.
