To adjust the hook to the right, loosen the two
screws in the right collar. Move the collar to the left on
its shaft. Move the shaft to the right. You will notice that
the shaft, hook and shuttle will all move together. Rotate
the balance wheel so that the hook is at the top of its travel
where it would cross the needle. Leave off the retaining
ring. To get the hook as close to the needle as possible
without touching it, move the shaft. Holding the correct
position of the shaft, carefully move the collar to the far
right, leaving no lateral play, then tighten its screw.
Holding the shuttle right, loosen the screw on the
compressible clamp and move the clamp to the far left
position. Be sure that the clamp gap is aligned with the
reference mark that was made. When the clamp screw is
tightened, there should be no side–to–side play in the shaft.
