Replace existing dobby air lines
You no longer need the "T" air line fittings that provided air pressure to the
advancing hook air cylinder, so you now need to remove the 2 air lines that
contain the "T" fittings. Replace 1 line at a time to be sure the new line is
placed into the correct air line fittings at the harness lift air cylinder and
main dobby air valve. The new lines will have no "T" fittings, just straight
lines from the existing fittings in the valve and the air cylinder.
1)
Locate the new lines that came with your compu-dobby and place
them near the loom.
2)
Locate the lines that run from the main dobby air valve mounted on
the inside of the bottom frame member, up to the large harness lift
air cylinder.
3)
Remove one of the lines with the “T” fittings.
4)
Place one of the new lines in the spot where you removed the
existing line.
Replace T fitting
with straight hose.
