Setup and Initial Configuration
Unpacking and Placement
Carefully remove the machine from its packaging. Place the serger on a stable, level surface with adequate lighting. Ensure sufficient space around the machine for fabric handling and accessory storage.
Power Connection
Connect the power cord to the machine and then to a suitable electrical outlet. Verify that the voltage matches the machine's requirements (120V, 60Hz).
Threading the Machine
The SINGER Professional 5 features a color-coded threading system to simplify the process. Follow the diagram located on the machine's front cover for guidance. Each thread path is clearly marked with a specific color, corresponding to the tension dials and thread guides.

Threading Steps:
- Raise the presser foot and open the front cover.
- Follow the color-coded guides for each thread, ensuring the thread passes through all designated points.
- Use tweezers (included) to assist with threading the loopers and needles.
- Close the front cover once threading is complete.
Tension Adjustment
The machine features a fully automatic self-adjusting tension system. This system automatically balances the thread tension for various fabrics and stitch types. Manual adjustments are generally not required, but can be fine-tuned if necessary using the tension dials.

Differential Feed
The differential feed system allows for precise control over fabric feeding, preventing stretching on stretchy fabrics and puckering on delicate materials. Adjust the differential feed dial according to the fabric type and desired effect.
