Where is the manual slide out override on my 2011 Komfort?

Some have a hole in the side of the trailer for a crank. My trailer has a small crank that fits on a bolt under the trailer on the slide out motor or gear case. It has been a long time since I was under there so can't remember exactly. If you don't see a small hole, crawl under and look at the slide mechanism. You should find some way of turning the motor or shaft. Might be with just a wrench and not a special crank.
