This may seem obvious to more experienced users, however, I’ve never used a mortiser before and the instruction manual is a little vague regarding setting the height of the motor and head.
I assume you need to loosen the set-screws and nuts on the right side of the mortiser’s head on the General model to set the height. Question is how tight do you put the set screws in order to hold the head at the right height, but still allow the handle to move mortiser head down easily. Again, probably obvious but I don’t want to screw up a brand new machine. Thanks for your time and help, as always its appreciated.
