Note! For the following step, a minimum 7 ½" (190 mm) long wrench is required.
A T-handled wrench is recommended. If a standard Allen wrench is used,
additional leverage may be needed to turn the nut.
3. Insert an 5/16" (8 mm) Allen wrench through the hole at the end of the
arm and insert into the adjustment nut.

4. If the arm section is drifting either up or down, rotate the adjustment nut
in the needed direction until the drifting stops:
– Rotate clockwise to increase the upward force on the arm.
– Rotate counterclockwise to decrease the upward force on the arm.
5. Continue turning the nut in the same direction, counting the turns, until
the arm starts to move in the opposite direction. Then turn the
adjustment nut the opposite direction ½ the number of turns counted.
6. Follow the steps outlined in Closing an End of the Articulated Arm on
page 1-10 to install the trim cover and restore power.
