LFS Height Adjustable Arm Tension
Adjustment
a. Check the vertical tension adjustment of the
Height Adjustable Arm for its capacity to support
the flatscreen monitor throughout its range of mo-
tion. The monitor should move freely yet maintain
its selected position without drifting. If an adjust-
ment is necessary, refer to figure 19 and proceed
as follows:
NOTE
The System can support and balance a
monitor weight up to 20 lbs. Exceeding
the weight will result in poor balance
and performance.

adjustment nut. Insert a 1/8" pin punch into a hole in
the adjustment and turn the nut as required to

Replace access cover when adjustment is com-
plete.
