WARNING! Keep fingers away from moving parts, especially the needle area. Always turn off the power when threading or changing accessories.

First-Time Operation

Power on the machine; the LED light will illuminate.

1. Select a stitch: Turn the stitch selection dial to your desired pattern (e.g., straight stitch #1).
2. Adjust stitch settings: Set the stitch length and width dials as needed for your fabric.
3. Position the fabric: Lower the presser foot onto the fabric at the starting point.
4. Start sewing: Gently press the foot controller. Use the reverse lever to backstitch at the start and end.
5. Practice: Sew on scrap fabric to test tension and stitch appearance before starting your project.

Stitch Selection & Settings

The machine offers utility, decorative, and stretch stitches for various fabrics and projects.

2. Consult the stitch guide to select the appropriate stitch pattern.
3. Set the stitch length: Shorter for finer fabrics, longer for basting or heavy fabrics.
4. Set the stitch width: For zigzag or satin stitches, adjust width for desired effect.
5. Test on a fabric scrap to ensure proper tension and appearance.

Tip: For stretch fabrics, use a stretch or narrow zigzag stitch to maintain seam elasticity.

Basic Sewing Techniques

Master these fundamental techniques for successful sewing.

1. Straight Stitching: Use for seams, topstitching, and basting. Guide fabric edges along the seam guide.
2. Zigzag Stitching: Prevents fraying and sews elastic. Adjust width for finish or decorative effect.
3. Buttonholes: Use the one-step buttonhole foot. Mark button placement, select buttonhole stitch, and follow the automatic cycle.
4. Blind Hem Stitching: Use the blind hem foot and stitch for nearly invisible hems on garments.
5. Decorative Stitching: Select a decorative pattern and practice on scrap fabric to align designs.

WARNING! Always match needle type and size to your fabric. Replace bent or dull needles immediately to prevent skipped stitches or fabric damage.

Maintenance & Cleaning

Regular maintenance ensures optimal performance and longevity.

1. Unplug the machine before any cleaning or maintenance.
2. Remove lint and dust: Use the small brush to clean the bobbin area, feed dogs, and needle plate after each project.
3. Oil the machine: Apply a drop of sewing machine oil to the hook race and other moving parts as indicated in the manual (usually after every 8-10 hours of use).
4. Needle replacement: Loosen the needle clamp screw, remove the old needle, and insert a new one with the flat side facing the back.
5. Storage: Cover the machine when not in use to prevent dust accumulation.

CAUTION! Use only Brother-recommended accessories and oil. Do not use compressed air to clean the machine as it can force lint deeper into the mechanism.
