Removing The Bobbin - Brother T-8420C Instruction Manual

5. PREPARATION BEFORE SEWING

5-2. Removing the bobbin

Turn off the power switch before removing the bobbin. 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.
