i have a c2 model when i wanted to change the seal (rubber) and screwed it down, the mechanism will not work as it is too tight this is with the unit removed out of the caravan the only way to use it is with the screws not tighened up properly.
without the seal the blade works as it should do with no problem.
i have put the seal with the cutouts facing up as they should be.
