opposite direction of the arrow, and firmly tighten the screws.
2) For the standard adjustment, adjust so that the top surface of feed dog and the top end of needle eyelet are flush
with the top surface of throat plate when the feed dog descends below the throat plate.
3) To advance the feed timing in order to prevent uneven material feed, move the feed eccentric cam in the direction of the
arrow.
4) To delay the feed timing in order to increase stitch tightness, move the feed eccentric cam in the opposite, direction from
the arrow.
