The standard timing of the feeding: Main feed dog should be at the same level as upper surface of needle plate
when needle goes down and point of it touches upper surface of needle plate.
As the needle is descending and about to enter the needle plate hole, the feed dog must be positioned as shown
in the illustration.
NOTE • Before the adjustment, check the Height of the feed dog and set the "Sewing pitch" at "3".
• Fabrics will not be fed straightly in case feed dog is inclined.
1. Open the cloth plate cover and loosen the set screw, socket M 5 × 6 (two) of the feed eccentric wheel by means of
a hexagonal wrench.
2. Turn the feed eccentric wheel to adjust the timing as shown in the illustration.
• In case of early timing, in other words when the feed dog is still positioned over the needle plate, turn the wheel in
direction A .
• In case of late timing, in other words when the feed dog is already positioned under the needle plate, turn the wheel in
direction B .
3. Tighten the set screw, socket M 5 × 6 (two) well.
