easier.
Important: Always make sure that the whole screw is seated com-
pletely on the surface.
4.6 Locking the sewing machine in place
With some settings, the machine has to be locked in place. To do this, the
locking peg from the accessory pack is inserted into a groove on the arm
shaft crank to block the arm shaft.

There are two securing positions:
•Position 1: Loop stroke position
• 5 mm end in the large groove
• Setting the loop stroke and needle bar height
