12. Adjustment of looper thread cam
(1) Adjustment of looper thread cam

is turned counterclockwise and the fi rst setscrew

of the looper
thread cam

and another fi rst setscrew
4
of the pulley
1
are aligned to the same line.
When two main shaft setscrews
4
and

are turned counterclockwise, the fi rst screw
functions as the main shaft contact setscrew

.

, loosen the setscrew
7
, and remove the cam thread path base

1. The looper thread cam
2
can be adjust-
ed through the peep window. However,
since the inside is dark, a proper light
(pen light or the like) should be used
during adjustments.
2. If the standard position is not secured
for the looper thread cam
2
, this can
be a cause of stitch skipping.
3) Install the cam thread path base
8
so that it does not
touch the right and left faces of the looper thread cam
2
. Then, tighten the setscrew
7
.
At the time of looper thread cam
2
adjust-
ments, do not move the looper thread cam
2
to the right and left.
If it is moved to the right and left, the looper
thread cam
