Adjustment of the parallelism and lengthwise movement of the Feed Dog
Requirement

parallelism
between both sides of feed dog and needle plate (A) should be even.
The clearance between the front end of the center feed dog and center slot (B) should be 4.5 +- 0.3 mm when
the stitch length dial is set at 0.

Adjustment
• Remove the base
• Lay the machine on its back.
• Set the stitch length dial at 0.
• Loosen the setscrews (C).
• To adjust the lengthwise movement (B) between the front and end of the center feed dog and center slot
, move the feed base (D) up or down to 4.5 mm.
• To Adjust the
parallelism
of the feed dogs move the feed rock shaft (E) to the right or left.
• Tighten the setscrews (C).
