(4) - Lower shaft
Important
If the dimension does not match the calculated dimension for the needle
evasive movement, the lower shaft (4) must be loosened and adjusted.
An adjustment in the axial direction changes the ellipsis width at a ratio of
1:2, i.e., when the lower shaft is moved, e.g. by 0.2 mm, the ellipsis width
changes by 0.1 mm.
Disturbance
• Damage to the looper
• Damage to the needle
• Missing stitches
• Thread breakage
