Threading The Upper Thread - Brother S-7300A-333P Instruction Manual

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.
