*Make sure the bobbin case is empty before trying to fill another bobbin. If there is a bobbin left in the bobbin case when winding a new bobbin a thread jam will occur in the bobbin case. Congratulations! You just broke it!

*In the instruction for the demo students should be encouraged to do test samples before stitching on their actual project.

====General maintenance====
*Clean lint, thread, and debris from feed dogs, bobbin area, and under needle plate after each use.
*Oil moving parts according to the manual - use sewing machine oil only and avoid over-oiling.
*Check belt tension and condition - replace if frayed, cracked, or slipping.
*Inspect needle for bending, dullness, or burrs - replace regularly to maintain stitch quality.
*Keep tension discs clean and free of lint or residue.
*Verify presser foot pressure and feed timing periodically - adjust as needed for consistent fabric feeding.
*Tighten screws, nuts, and bolts to prevent vibration-related loosening.
