7.

Set each dial to zero by turning the indicator’s outer ring.

 Turn the dial to zero, then turn it past zero by two full rota-

tions before arriving at zero again. These ex tra rotations give
the dial room to move and adjust on either side of zero as
you adjust the neck. The thumbscrew locks the outer ring.

8.

Return the Neck Jig to the horizontal working position

and remove the guitar’s strings. Adjust the peghead jack
until it fits loosely between the beam and the end of the
peghead. Install the peghead pull-down strap allowing a
small amount of slack.

Caution:

Before tightening the body straps, lower

the  neck  support  rods.  Tighten  the  hold-down

strap gradually until the guitar body is snug on the levelers.
Sometimes a guitar will require two straps in order to se cure
it on the levelers.

6.

With the guitar tuned to pitch, move the Neck Jig onto

its side (the playing position). Adjust the neck for fret level-
ing or dressing; the truss rod should create backbow when
tightened and create relief when loosened. You want the
neck to be straight for fret work.
