3. Follow threading path: From spool pin through guides, tension discs, take-up lever, to needle.
4. Thread needle: From front to back.
5. Bobbin threading: Wind bobbin evenly, insert into case with thread following tension spring.
6. Pull up bobbin thread: Hold needle thread, turn handwheel to lower then raise needle, pull needle thread to bring up bobbin loop.

Tip: Always thread with presser foot raised and needle at highest position.

Stitching Operations

1. Position material: Place item on cylinder bed under presser foot.
2. Lower presser foot: Use lever or knee lift.
3. Start sewing: Depress foot pedal or engage clutch motor.
4. Reverse stitching: Engage reverse lever at beginning and end of seam for reinforcement.
5. Guide material: Let feed mechanism pull material; do not push or pull forcefully.
6. Stop sewing: Release foot pedal, raise needle to highest position, raise presser foot, remove material.
7. Trim threads: Use built-in thread cutter or scissors.

WARNING! Never place fingers near needle while machine is running. Use appropriate guards.

Maintenance & Lubrication

Automatic lubrication system requires regular monitoring.

1. Daily: Check oil level in reservoir, refill as needed with recommended oil.
2. Weekly: Clean lint and debris from feed dogs, bobbin area, and hook.
3. Monthly: Check for oil leaks, inspect drive belt tension.
4. Every 6 months: Change oil in reservoir, clean oil filter.
5. Annually: Professional service recommended for timing adjustment and thorough cleaning.

CAUTION! Use only recommended sewing machine oil. Do not overfill reservoir.

Care & Cleaning

Disconnect power before cleaning. Remove lint buildup regularly.

1. External surfaces: Wipe with dry, soft cloth.
2. Internal mechanisms: Use small brush to remove lint from feed dogs, bobbin case, hook.
3. Oil system: Check for clogs in oil lines.
