Flats On Shafts; Locking The Sewing Machine In Place - DURKOPP ADLER M-TYPE 667 Service Instructions Manual

3.4 Flats on shafts

Fig. 7: Flats on shafts
Some shafts have flat surfaces at the points where the components are
screwed on. This stabilizes the connection and makes adjustment easier.
Important
Always ensure that the screws are completely flush with the surface.

3.5 Locking the sewing machine in place

For some settings, the machine must be locked in place. To do this, the
arresting pin from the accessory pack is inserted into a slot on the arm
shaft crank, blocking the arm shaft.
