Threading The Upper Thread - Brother Z-8550A Instruction Manual

5. PREPARATION BEFORE SEWING

5-5. Threading the upper thread

Turn off the power switch before threading the upper thread.
The machine may operate if the treadle is dep ressed by mistake, which could result in injury.
If the actuator is pressed by mistake when using the correction sewing function, the needle will move in a zigzag
motion while the machine is operating, and injury may result.
Turn the sewing machine pulley to align the reference line (1) on the pulley with the indent (2) in the motor cover (needle up
stop position).
This will make threading easier and it will prevent the thread from coming out at the sewing start.
