⑷ Needle height
0.5~1.0mm
When the end tip of the looper passes the left needle center, it must pass the needle groove at 0.5~1.0 mm off from the
upper part. In other words, the height of the needle is set by the looper.
Using a driver, unfasten the screw① of the needle bar holder through a hole in the face plate and adjust the needle bar up
and down to get the right needle height.
⑸ Front/rear position of needle and looper
The recommended clearance when the end tip of the
looper① meets the left needle is 0.2 ~0.3 mm. For
adjustments, unfasten the screw④ of the looper holder.
⑹ Needle and needle guard(rear)
※ When needle guard (R) is at the lowest point of the
needle bar, align the center of the needles along the
line② of the needle guard (R) ①.
