8) Adjustment of location detector
A. For in-built location detector
Adjust the up-stop position of the needle such that the white carved sign on the pulley
is in a straight line with the carved sign
on the arm
when the needle has stopped in the air. That adjustment can be made by loosening the pulley’s clamp screw
on
the side with N U carved signs and moving it sideways. Adjust the down-stop position of the needle such that the needle is on
the point of moving up when the needle bar is at the lowest point. This adjustment can be made by loosening the pulley’s clamp
screw
on the side with N D carved signs and moving it sideways. (See, Figure 13&14)
