3.6 Locking the machine in place
For some settings, the machine has to 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.
There are 2 securing positions:
• Position 1: Loop stroke position
• 5 mm end in the large slot
• Setting the loop stroke and needle bar height
• Position 2: Handwheel zero position
• 3 mm end in the small slot
• Setting the handwheel position and checking the bottom dead cen-
ter for the needle bar
