4. ADJUSTING THE NEEDLE RELEASE
4.1. When the needle is in the upper needle bar turn the handwheel so as the needle is in the
position right after shifting into the lower needle bar. Slightly turn the handwheel back
and forwards to test the needle releases from the upper needle bar.
4.2. Loosen the nut
on the upper part of the needle bar. Turn slightly the adjusting nut
anticlockwise when seeing it from above until the needle is released in the transfer point.
Turn it back clockwise by another half turn. Tighten the nut
.
4.3. Slightly move the handwheel forward and backwards to be sure that the needle is shifted
properly from one needle bar to another. You should feel no resistance while rotating the
handwheel, but the needle shall be shifted properly, i.e., you should not be able to pull it
into the needle-bar; you can test while holding the needle in pliers. The movement clear-
ance of the needle is 0.4 - 1.2 mm.
4.4. Carry out the same adjustment also in the lower needle bar to release the needle from
the lower needle bar into the upper needle bar.
