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.
