FIG. 20
Set rear needle guard (A, Fig. 18) so it touches the first (left)
needle (B) but does not deflect. Check the guard position to
the other needles to avoid pinching. Loosen screw (C) and
reposition guard (A) as necessary. Tighten screw (C).
SETTING THE STITCH LENGTH
This machine is designed to sew 10 to 16 stitches per inch. The
normal factory setting is 16 stitches per inch. To change the
stitch length remove the plug screw located directly above
the cylinder side cover. Loosen screw (A, Fig. 19) in lever (B)
and move up to increase the stitch length or down to de-
crease the stitch length. Tighten screw (A) and replace the
plug screw.
CAUTION:
If the stitch length is changed the rear needle
guard setting must be checked and readjusted
if necessary. Failure to do so may result in
needle and/or parts breakage.
CAUTION:
When making stitch length adjustment do not
exceed maximum recomended stitch length
due to possible part damage.
DIFFERENTIAL FEED CONTROL
The amount of differential feed is controlled by lever
(C, Fig. 19). The adjusting plate is numbered from 1 to
9. When the lever is set from numbers 1 to 4 reverse
differential or stretching occurs. The numbers from 4
to 5 produce equal feed stitching while numbers 5 to
9 produce a gathering stitch. The two stop screws (D)
can be set to limit the movement of lever (C) or lock
the lever in one position.
