Designed to Protect Your Machine
In the event of a bind or machine jam, the pin will break at the shear point (A), preventing the machine from operating,
when there is too much resistance on the machine. This prevents internal damage or misalignment. If the Posi-Pin
breaks, simply remove the broken pin, replace it with a new one and check the cap spring for damage (p. 38, 57). Then
install a new needle (p. 7) and verify that the needle bar height has not shifted (p. 45). You can then continue sewing
without issue.

NOTE: When the Ultrafeed is not being used, remove the Posi-Pin and place it in the Posi-Pin Keeper (B) or the storage cubby
(C). This is to prevent the compression shaft from enduring unnecessary deformity over time.
