Preva
105
Articulating
Arm Friction
Adjustments
The Preva has four friction adjustment points located at the four pivot points of the
Articulating Arm. These friction points can be adjusted to reduce or increase the
force needed to position the Articulating Arm.
1. Remove the plastic covers on the Articulating Arm to reveal the adjustment
points.
2. Using a 2 mm Allen wrench, as shown in Figure 104, tighten both screws
evenly at each adjustment point until the movement of the Articulating Arm is
as desired. Do not loosen adjustment points so far as to allow the Articulating
Arm to drift.
