Instructions for the differential feed mechanism

	This machine is equipped with two sets of feed dogs
	under the presser foot to move the fabric through the
(4)	machine. The differential feed controls the movement of
(4)	both the front and the rear feed dogs. When set at 1, the

		feed dogs are moving at the same speed (ratio of 1).
(3)		When the differential feed ratio is set at less than 1, the
(3)		front feed dogs move slower than the rear feed dogs,
		front feed dogs move slower than the rear feed dogs,
		stretching the fabric as it is sewn. This is effective on
		lightweight fabric that may pucker. When the differential
		feed ratio is set at greater than 1, the front feed dogs
		move faster than the back feed dogs, gathering the fabric
		as it is sewn. This function assists in removing the rippling
		when serging stretch fabrics.
		• To adjust the differential feed.
		(1)Locate the differential feed adjustment lever on the left
		side of the machine.
		(2)The normal setting is 1.0 on the differential feed
		adjustment lever.
		(3)To set less than 1.0, move the lever back.
		(4)To set greater than 1.0, move the lever forward.
