cause of needle and thread breakages. If the gap
between needle and hook is too big, it will cause to
skip stitches. Check and adjust as follows:
Prior to make this adjustment, check that the needle
is not bent and the needle is inserted correctly.

machine. Remove the needle plate and bobbin
holder.
2. Set the pattern at [Straight stitch No.1] and move
the needle position extreme to the left. (-3.5)

3. Turn the handwheel toward you until the needle
will cross over the hook.
4. Check the gap by pressing a small screw driver
against the needle. The gap should be 0.1- 0.2
mm.
Note:
Also, the needle should descend into the middle of
the needle hole of the needle plate in the feeding
direction.

is too much, adjust as follows:
