B. Chain Looper Thread Takeup Cam (Figure 15)
Set the chain looper takeup cam so that, when the needles are all the way up, the flat
Of the cam is horizontal. At this setting, the cam should release the chain looper thread
When the needles are 1/32 to 1/16 inch (1.0 to 2.0mm) below the needle plate.
C. Looper Thread Takeups and Guides
Figure 16 shows adjustments of the looper thread takeups and guides.
D. Edge Trimming Knives
1) Vertical Adjustment
a) Lower Knife height:
Loosen the set screw (2) Indicated in Figure 17, and adjust lower knife
(1) height to be fush with, or slightly below the top of the throat plate.
Tighten screw (2).
b) Upper knife Height (Figure 17)
Loosen set screws (4) and set upper knife height so that when it is at the lowest
point of travel, it overlaps the lower knife by between 1/64 and 1/32 inch (0.5-
1.0mm). Tighten not screws (4).
2)
Overedege Width Adjustment (Figure 17)
Overedge width is slightly wider than the knife cut width. To adjust loosen screws (5)
and push the lower knife (1) all the way to the left, and tighten screw (5). Loosen sel
screw (6) and position the upper knife (3) to the cut width required. Tighten screw (6),
loosen screw (5) and move the lower knife to the right until it contact the upper knife.
Tighten screw (5) firmly to prevent the internal spring from moving the lower knife
during operation. If screw (5) is not tight the knives will break.
3)
Knife Sharpening
The lower knife may be resharpened when it dulls. Figure 18 shows the correct
sharpening angles for the lower blade. The upper knife has a cemented caroide edge
which is considered ungrindable. Replace the upper knife when it becomes dull.
K. NEEDLE GUARDS
Incorrect needle guard settings are probably the single most common cause of thread,
looper and needle breakage, and of stitch skipping. Be certain needle guard settings
are measured properly, as indicated in Figure 19. Needle guards should be set to
eliminate excessive play or deflection of needles. If guards are set too light to
needles, breakage of threads, needles and/or loopers will occur. If settings are too
loose, stitches will skip.
