Adjustment Procedures
Results of Improper Adjustment
1) When sewing is completed, crank shaft is inverted to the original
state and presser goes up. To prevent interference with needle,
it is recommended to input a point being 10 mm away from the
center of crank shaft as the 2nd origin when creating a pattern.
2) When creating a pattern, and performing input by the optional
inverting, make sure that the number of inverting rotations of
the crank shaft is the odd number.
3) It is possible for the inverting clamp device to correspond with
cloth thickness up to 10.1 mm by setting the needle upper
dead point mode with the memory switch.
™
When the number of optional
inverting rotations is the even
number, the crank shaft does not
return to the initial position and
it may come in contact with
needle when sewing causing
needle breakage.
