5. PREPARATION BEFORE SEWING

5-5. Threading the upper thread

Turn off the power switch before threading the upper thread. The motor will keep turning even after the power is

switched off as a result of the motor's inertia. Wait until the motor stops fully before starting work.

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.
