Swing Arm Tension Adjustment
Swing arm tension is pre-set at the factory and is adjusted to
accommodate displays with weights near the top of the mounts
capacity.
If smaller displays are used it may be difficult to reposition the
display after mounting. Swing arm tension can be adjusted to
compensate for smaller display by:
The display must be mounted prior to adjusting swing arm
tension.
1. Locate the adjustment bar (K) and adjustment wrench (L).
2. Place adjustment bar (K) into socket head cap screw
located at swing arm pivot point. (See Figure 11)
NOTE: The display may need to be repositioned in order
to gain access to the tension adjustment
screw(s).
3. Check swing arm tension. If desired tension is present,
tension adjustment is complete. If additional tension
adjustment is required, repeat steps 2 thru 4 until desired
tension is achieved.
NOTE: If changing from a smaller display to a larger
display may be necessary to increase swing arm
tension.

4. Using the adjustment wrench (L), turn adjustment bar (K)
clockwise to increase swing arm tension or
counterclockwise to reduce swing arm tension. (Small
adjustments of 1/8 turn or less are typically all that is
required to achieve desired tension.) (See Figure 12) and
