1.Loosen the screw q, lower the presser foot w so that its bottom can lightly touch the workpiece, and tighten the screw q again.

Note: If the presser foot is lowered too far, the workpiece will shift when sewing. Also, if the presser foot is too high, skipped stitches may oc- cur.

2.Turn the pulley manually to make sure that the needle

enters the center of the needle hole in the presser foot w. If the needle is not aligned with the center of the needle hole, remove the cap e, loosen the screw r, and turn the presser foot (presser bar) for adjustment.

When the presser foot is in the high position and the needle point is projecting below the presser foot, it could cause injuries.
