ADJUSTING THE FRICTION POSITIONING (continued)

The amount of friction resistance should be set such that the arm is comfortable to move (always test both up and down movements), yet hold its weight against gravity once positioned.

To adjust the friction setting for side to side movement of the arm, use the top two bolt/nut sets on the rotat- ing hinge (Fig. 16A).

To adjust the friction setting for front to back move- ment, adjust the front bolt/nut set (Fig. 16E) on the rotating hinge.

To adjust the friction setting for the telescopic motion of the arm, remove the black cap (Fig. 16B) and turn the set screw (Fig. 16D):

Counterclockwise to increase friction and Clockwise to decrease it.

NOTE: Friction is only applied to the telescopic move- ment when pulling the hood down; gravity provides resistance when lifting the hood.
