CAUTION
• Do not grab the bar to raise the spool pin, 
otherwise, the spool pin may bend or break.
• Be sure to raise the spool pin when winding 
the bobbin. The thread may become tangled if 
the bobbin winder is used without raising the 
spool pin.

Fully insert the spool of thread for the 
bobbin, and then slide the spool cap onto the 
spool pin.
•The thread should be unwound from the 
bottom to the front.
CAUTION
• If the spool or the spool cap is not positioned 
correctly, the thread may become tangled 
around the spool pin or the machine may be 
damaged.
• Three spool cap sizes are available. Choose a 
spool cap that best fits the size of spool being 
used. If the spool cap is too small for the spool, 
the thread may catch on the slit in the spool or 
the machine may be damaged.

•When sewing with fine, cross-wound

small space between the cap and the spool.
