Pitch pocket cutter
When the pitch pocket cutter is used for the first time the slot for it in support (8)
must be prepared first. This is done by moving the pitch pocket cutter forward to the
cutting depth stop, which has been set to the maximum cutting depth, after the machine
has been switched on so that it will cut the necessary slot into the support.
Perspex base plate
Exchanging the normal base plate by the perspex base plate enables you to see
the cutter as well as the pitch pocket to be worked on.
Anti-slip mats, wrapped, 2 pieces
Store the machine only in dry rooms, where it is pro-
