Be sure to turn the power OFF before the following work in order to prevent personal injury due to unintentional starting of the sewing machine.

Standard feed timing

Advanced feed timing

Delayed feed timing

1) Loosen screws 2 and 3 in feed eccentric cam

, move the feed eccentric cam in the direction

of the arrow or opposite direction of the arrow,

and rmly tighten the screws.

For the standard adjustment, adjust so that the

top surface of feed dog and the top end of needle

eyelet are ush 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.

Be careful not to move the feed eccen-

tric cam too far, or else needle breakage may result.
