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.
