3.6 Locking the sewing machine in place
For 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 2 securing positions:
• Position 1: Loop stroke position
• 5 mm end in the large groove
• Setting the loop stroke and needle bar height
• Position 2: Handwheel zero setting
• 3 mm end in the small groove
• Setting the handwheel position and checking the bottom dead
center for the needle bar
