ADJUSTING THE NEEDLE GUARD
When the looper moves to the right from the extreme left
end of its travel, the looper passes behind the needle.
When the point of the looper has reached the centerline of
the needle, the needle should be 0~0.5mm deflected by
needle guard M. Adjustment is made by loosening screw
N. The needle guard should be installed as low as
possible. In addition, the needle must touch the needle
guard surface until the point of the looper passing behind
the needle reaches the right side of the needle.
Adjustment is made by loosening screw O.
< Note >
Since the needle guard is installed on the feed dog bracket,
the relationship between the needle and the needle guard
varies according to the stitch length. Therefore readjust the
needle guard if the stitch length is changed.
