Ensure the machine is turned off before connecting or disconnecting the foot controller. Avoid using damaged cords or exposing the machine to water. Always follow these guidelines to ensure safe operation and prevent electrical hazards.

Threading and Basic Setup

Proper threading and setup are crucial for smooth operation. Wind the bobbin correctly, thread the machine, and ensure all parts are aligned. Use compatible bobbins and follow threading guidelines to avoid issues.

4.1 Step-by-Step Guide to Threading the Machine

Begin by winding the bobbin with compatible thread (part code: SA156). Pull thread through the pre-tension disk and wind firmly. Trim excess thread above the bobbin.
Insert the wound bobbin into the shuttle race, ensuring it clicks into place.
Thread the upper part by pulling thread from the spool pin, guiding it through the rear and front thread guides, and take-up lever.
Draw up the lower thread by turning the handwheel and gently pulling the upper thread.
Ensure both threads are properly tensioned for smooth stitching. Always use Brother-recommended bobbins to avoid issues.

4.2 Winding and Installing the Bobbin

Use only Brother-recommended bobbins (SA156). Place the bobbin on the winder, pull thread through the pre-tension disk, and wind evenly. Avoid crossing threads.
Trim excess thread above the bobbin.
Open the shuttle cover and insert the bobbin into the shuttle race, ensuring it clicks into place.
Pull the trailing thread through the slot and guide it under the tension spring. Always use correct bobbins to prevent needle breakage and ensure proper thread tension for consistent stitching.
