Maintenance Guide
Daily Cleaning
Remove lint and dust from bobbin area, feed dogs, and needle plate after each use. Use small brush and compressed air for thorough cleaning.
Monthly Oil Maintenance
Apply sewing machine oil to designated points: hook race, bobbin case, and moving joints. Use only high-quality sewing machine oil.
Needle Replacement
Replace needle after every 8 hours of sewing or with each new project. Bent or dull needles can damage fabric and machine components.
Belt Inspection
Check drive belt for cracks, glazing, or looseness every 6 months. Replace if signs of wear appear to prevent motor strain.
Tension Adjustment
Regularly check thread tension using test fabric. Balanced tension ensures proper stitch formation and prevents thread breakage.
Professional Service
Schedule professional servicing every 1-2 years for complete cleaning, lubrication, and adjustment of all mechanical parts.
