SETTING NEEDLE THREAD TAKE-UP AND FRAME EYELET
1/16"
(1.6mm)
FIG. 20
FIG. 21
With the needle bar at the top of its stroke set the adjustable
frame needle thread eyelet (A, Fig. 20) in the lower mounting
hole of eyelet (B) so the needle thread from eyelet (A) to the
needle lever thread eyelet (C) will be in a straight line. If
adjustment of eyelet (A) is necessary loosen screw (K) and
move eyelet up or down as required. Retighten screw (K).
With the needle bar at the bottom of its stroke, the needle
thread take-up (D) should be set so that it is 1/16" (1.6mm)
above the edge of the needle lever thread eyelet (C) (See
Inset). If adjustment is necessary loosen screw (H) and adjust
lever (D) as required to attain 1/16". Tighten screw (H).
LOOPER THREAD TAKE-UP ADJUSTMENT
With the machine rotating in operating direction the looper
thread take-up is in time when the first screw coming into
view (A, Fig. 21) is in line with the spot screw (B) on the main
shaft in the pulley. NOTE: screw (A) is accessable through the
hole in the take-up. With this setting correct, the looper
thread should cast-off of the take-up (C) when the needles
are safely in the triangle. If adjustment is necessary loosen
two screws (A) in take-up (C) position screws in line with spot
screw (B). Tighten screws (A).
NOTE:
Make sure take-up cam is centered left to right in
cast-off slot.
