4. PREPARATION BEFORE SEWING

4-5. Threading the upper thread

Turn off the power switch before threading the upper thread.

The machine may operate if the treadle is depressed by mistake, which could result in injury.

・ Turn the machine pulley and raise the thread take-up (1) before threading the upper thread.

This will make threading easier and it will prevent the thread from coming out at the sewing start.

・ Thread the left-side thread first.
