MODIFICATION
If desired, each arm assembly (10) may be modified to
prevent movement of the outer arm relative to the inner
arm (without loosening the adjustment screw).
NOTE: Spacer (shipped configuration) will allow limited
movement of outer arm relative to inner arm,
dependent upon tension of screw. Washer (80)
will lock arms together. See "ADJUSTMENT" for
detail.
1. Using 3/16" hex key, loosen screw until nut can be
removed (See Figure 19). Retain nut. Screw and
washers may remain in outer arm.

(See Figure 19).
