To adjust the height of the needle guard (rear), align
the top of the right needle's eye with line A on the
needle guard (rear) when the needle bar is at the
bottom of its stroke.
■
When the point of the looper has reached the center
of the right needle, push out the needle guard (rear)
slightly toward you. Then there should be a
clearance of 0~0.05mm between the needle and the
looper. In addition, there should be a clearance of
0.05~0.1mm between the left needle and needle
guard (rear). Adjustment is made by loosening
screws (B) and (C). Be careful that the relationship
between related parts is not changed.
< Note >
After the above adjustment, retighten the screws
securely so that the needle guard (rear) will not move
left-to-right.
