The differential feed mechanism (refer to Figure 3.6) allows you to adjust the feeding ratio of the front and rear feed dogs. This is essential for preventing stretching on knit fabrics or gathering on fine fabrics.

• Normal Feed (N): For most woven fabrics.
• Gathering (1.5 - 2): For intentionally gathering fabric.
• Stretching Prevention (0.7 - 0.9): For preventing stretching on knit fabrics.

Regular cleaning is vital for optimal performance. Use a small brush and vacuum cleaner to remove lint and thread scraps from the looper area, under the needle plate, and around the feed dogs. Always disconnect power before cleaning.

6.2 Mazání olejem

Apply a small drop of high-quality sewing machine oil to the designated oiling points as indicated in the detailed diagram within your machine's internal cover or the full printed manual. Oiling should be done periodically based on usage.

6.3 Výměna jehly

Use only 130/705H type needles. Replace needles regularly, especially if they become bent, dull, or if you experience skipped stitches. Ensure the flat side of the needle faces the back of the machine when inserting (refer to Figure 3.5).
