Clean the hook, inspect the needle plate and feed dog, pick the right needle size — three steps for smoother heavy-material stitching.
1. Brush lint off the hook and feed dog before startup to keep feeding rhythm stable.
2. Check needles for burrs; size 16–18 is recommended for leather.
3. Oil the hook weekly — a visible oil line is enough.
4. Test on scrap material before switching to thick fabric, and confirm top/bottom feed are synchronized.
