a Using a short-handle 1-1/2-inch wrench, loosen both nuts on the side of the mount.
The inner nut is the clamping nut. The outer nut is the locking nut.
b Slide the entire mount toward or away from the alignment fixture.
Sliding toward the fixture raises the crosshairs on the circle. Sliding away from the
fixture lowers the crosshairs on the circle.
c Using a short-handle 1-1/2-inch wrench, tighten the clamping nut to a torque of 48
to 50 foot-pounds (65.1 to 67.8 newton-meters) .
Don't exceed a torque of 50 foot-pounds (67.8 newton-meters). Doing so can
cause failure of the mount.

50 foot-pounds (65.1 to 67.8 newton-meters) .
Don't exceed a torque of 50 foot-pounds (67.8 newton-meters). Doing so can
cause failure of the mount.
