• Set the memo-42 switch to "5".

1. 1/2 reverse mode

1. Reverse stitching is possible within 4.5 mm left and
right from the reference point.
However, note that if a non-standard work clamp
is being used, the reverse stitching area will be-
come smaller.
2. When the work clamp q reverses after sewing is
completed, the work clamps are retracted so that
they do not touch the needle. However, sometimes
it is not necessary to retract the work clamps if the
material is thin.
In such cases, if memory switch memo-15 is set to
on, the work clamps will not be retracted so that
the cycle time can be shortened. However, if mak-
ing this change to the setting, move the work clamp
to the sewing end position (release the air and
move the work clamp by hand) to check that the
work clamps do not touch the needle.
