When threading the sewing machine, be sure that one of the presser feet mentioned in this Operation Manual is installed.

The needle threader lever can only be used with home sewing machine needles size 75/11 - 100/16.
Check the table on page 26 for appropriate needle and thread combinations.
Note that, if you are using transparent nylon mono-filament thread, only needles in the range of 90/14 - 100/16 can be used.
* You do not need to pull the bobbin thread up before you start sewing.
Always raise the presser foot before removing the upper thread from the machine or damage may occur to the tension unit.
The needle threader lever can not be used to thread the needle when you are using decorative threads or specialty needles like the twin needle and wing needle.
When using those types of threads or needles, thread the eye of the needle manually.
Make sure the main power switch is OFF when threading the needle manually.
