ADJUSTING THE FRICTION OF THE
TELESCOPIC ARM
(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 position 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. 5A).
To adjust the friction setting for front to back move-
ment, adjust the front bolt/nut set (Fig. 5E) on the
rotating hinge.
To adjust the friction setting for the telescopic motion
of the arm, remove the black cap (Fig. 5B) and turn
the set screw (Fig. 5D) counterclockwise to increase
friction and clockwise to decrease it.
