When using sewing thread spools, the thread spool cap should be used as illustrated below.
Make sure that the spool notch is on the bottom.
(1) Thread spool cap
(1) Spool support
(2) Spool cushion
When using thread spools or loosely spun thread that easily slips off the spool, place this mat under the spool.
This prevents the thread from becoming entangled on the spool pin.

If the thread spool cap is not fully pushed down against the thread spool, the thread may become entangled on the spool pin or the needle may bend or break.
If you are sewing with loosely spun nylon thread, we recommend that you cover the spool with the included net in order to prevent the thread from slipping off the spool.
Adapt the net to the shape of the spool.

Move the needles to their highest positions before threading.
