Trace the cable back through
its pulleys in the Harness
Pulley Support and make sure
that the cable is properly
seated. Check the action of the
Dobby Cable as well. Make
sure that it moves easily up
and down. If the Dobby Cable
seems to bind, check for debris
n the hole where it comes
through the Dobby Top. You
may need to use a very thin
piece of wire to dislodge
accumulated yarn dust or
other debris.
Reduce the warp tension at the
Tension Tie-Up or add
additional springs to the
harnesses.
Concentrate on getting both
treadles all the way through
their travel.

to the assembly instructions.
Rearrange the cables.
