Turning direction
The loopers run in back of the needle in their
forward travel and in front of the needle in th-
eir backward travel.Adjust the clearance bet-
ween the needles and the loopers to anywhere
from 0.05 to 0.10 mm in the forward travel.
Remove forward feed arm cover .
The forward/back looper timing should be
adjusted so that the set screw which is at the
rear relative to the forward/back cam turning
direction is aligned with the screw adjustm-
ent hole when the set screw which is at t-
he rear relative to the up/down cam turning
direction is aligned with the looper connec-
ting rod adjustment hole .
To adjust,loosen the set screw which is at t-
he front relative to the forward/back cam t-
urning direction,and then loosen the set scr-
ew at the rear just enough so that the forwa-
rd/back cam can be adjusted.
Loosen the looper holder screw ,and then
move the looper holder in the direction of
the arrow to adjust so that the clearance be-
tween the tip of the looper and the center of
the needle is 0.05mm -0.10mm when the t-
wo are aligned.
At this time,do not move the looper holder
in any direction except the direction indica-
ted by the arrow.if it is moved in another d-
irection.
Install the forward feed arm cover .
