By all means do fix the chain. However, there is still a reason to have a kneel-defeat switch. Depending on where you live, this may be a rare situation or a somewhat common one - you need to drop the ramp onto a high sidewalk and kneeling would put the car end of the ramp lower than the sidewalk end. So, I'd try to find out where that switch is too (or install one if there isn't one, though there probably is). If you can't find it, you can call or write to Braun. Ciao, Lenny
