5.1 Adjustment of the rubber buffer
To protect the needle, the rubber buffer can be adjusted such way that the needle will no longer strike the
glass plate but the rubber buffer just in front of the glass plate instead.
Behind the drop rod there is a screw on which the rubber buffer is screwed. This screw is secured by a
nut.
