REGULATION
LENGTH OF STITCH, ON MACHINE 331K1:
The length of stitch is regulated by moving the
pointer in the stitch indicator plate on the front of the
machine as instructed in Fig. 23.
When pointer is set at 0 there can be no feeding
motion.
Maximum length of stitch is 5Vb stitches per inch.
Move pointer to desired length of stitch and firmly
tighten thumb screw.
LENGTH OF STITCH, ON MACHINE 331K4:
Depress the feed-reversing lever slightly and turn
thumb screw over to the left to lengthen the stitch or over
to the right to shorten the stitch, as instructed in Fig. 24.
Thumb screw is marked with numerals from “0” to
“5”.
When thumb screw is set at “0” feed reversing lever
is fixed at central position and there can be no forward
or reverse feeding.
When thumb screw is set at “5”, machine will feed at
maximum stitch length.
REVERSE FEED, ON MACHINE 331K4:
(See instructions in Fig. 25)
Fig. 24. Regulating Length of Stitch on Machine 331K4
Fig. 25. Reversing the Feeding Movement
on Machine 331K4
Simply depress the feed-reversing lever as far as it
will go.
Feeding in reverse continues only as long as lever is
held in depressed position.
Forward feeding is resumed upon release of lever.
Direction of feed can be reversed at any point in a
seam while machine is in operation, without disturbing
the work. Back tacking is therefore readily accom­
plished and ends of seams are easily fastened.
The range of movement of feed reversing lever is
limited by the setting of thumb screw as instructed
above under stitch length regulation.
When lever is released it will rise to highest point
permitted by setting of thumb screw and machine will
stitch forward at the set stitch length.
When lever is depressed as far as permitted by the
thumb screw setting, machine will feed in reverse at the
set stitch length.
