2-11. OPERATING PROCEDURES FOR CLOTHING SEWING MACHINE - continued.
Adjusting Stitch Length.
(1) The stitch length is regulated by turning dial (1) at the front of the machine. When number "0" on
the dial appears uppermost, the machine does not feed. Turning the dial to the left will gradually
increase the stitch length to its maximum ( 1 to 5 ), when "5" is at the top. As the stitch length is
increased, it can be noticed that the tacking lever (2) slowly moves in an upward direction.
(2) When shortening the stitch length, it will be an advantage to depress lever (2) slightly as dial (1)
is being turned to the right. To do tacking for the purpose of locking the ends of seams, rapidly
depress and release lever (2) as the needle approaches the edge of the material.
Operating the Clothing Sewing Machine. After the machine has been prepared for operation, operate
as follows using excess cloth. Make all thread and presser foot adjustments before starting repairs.
Always rotate the machine hand wheel towards you. Turning the hand wheel away from you will
break or bend needles or damage bobbin case or oscillating shuttle.
Before making clothing repairs, make sure of the adjustments by using a piece of scrap cloth.
