I found myself in a situation last year where the information about removing a single screw, lifting the motor and pushing, albeit, really hard, would have saved me four hours of trouble shooting, an upset spouse and a really crumby end to an amazing trip.
Please put this information in your user manual. You will have less than pissed off customers when your product fails (7 months after purchase). Knowing what to do, I would have continued my trip and dealt with the issue later, grumbling while moving the slide manually each day.
All is well, they fixed the problem as expected and it has worked well since. Chock it up to a simple physical manufacturing defect. A little information would have made the difference of a really upset customer versus one that was somewhat annoyed.
