Threading the Machine

Correct threading is essential for proper stitch formation.

1. Top Thread:
   1. Place spool on the vertical spool pin.
   2. Follow the numbered threading guide on the machine: through the first thread guide, down the tension assembly, up and through the take-up lever, then down through the final guide(s) to the needle.
   3. Thread the needle from front to back.
2. Bobbin (Bottom Thread):
   1. Wind a Class 66 metal bobbin evenly using the built-in winder.
   2. Insert bobbin into the shuttle with the thread running counter-clockwise.
   3. Pull the thread through the slot and under the tension spring.
3. Bring Up Bobbin Thread: Hold the top thread tail. Turn the handwheel toward you one full rotation to lower and raise the needle. Pull the top thread to bring the bobbin loop up. Pull both thread tails under and behind the presser foot.

Tip: Always have the presser foot UP when threading the top tension discs.

Basic Sewing Operation

1. Fabric Placement: Raise the presser foot. Place fabric under the foot, aligning the edge with your desired seam guide.
2. Lower Presser Foot: Gently lower the presser foot lever.
3. Start Sewing: Depress the foot control lightly to start slowly. Guide the fabric gently; do not push or pull.
4. Reverse: Press and hold the reverse lever at the start and end of a seam for 2-3 stitches to lock stitches.
5. Finishing: Stop sewing. Raise the needle to its highest position using the handwheel. Raise the presser foot. Pull the fabric to the rear and cut threads using the built-in thread cutter or scissors.

WARNING! Never sew over pins. Remove them as you approach them with the needle.

Maintenance & Lubrication

Regular maintenance ensures longevity and smooth operation.

Daily: Brush out lint from the bobbin area and feed dogs.
Weekly (or after 8 hours of use): Add 1-2 drops of high-quality sewing machine oil (Singer All-Purpose Machine Oil recommended) to all oiling points shown in the manual's diagram. Key points include: the take-up lever, needle bar, presser foot bar, and shuttle race.
Procedure:

1. Unplug the machine.
2. Remove the needle, presser foot, and throat plate.
3. Apply oil sparingly to moving joints and bearings.
4. Run the machine without thread for a minute to distribute oil.
5. Wipe away any excess oil with a soft cloth.

CAUTION! Use only sewing machine oil. Do not use household oils or WD-40. Over-oiling can attract lint and stain fabric.

Needle & Presser Foot Guide

*Specialty feet may require an adapter. Always use a sharp needle. A dull or bent needle is the most common cause of skipped stitches and thread breaks.

Troubleshooting Common Issues

Reset: For persistent issues, unplug, clean thoroughly, re-oil, and re-thread completely.
