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.

NOTE: 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 10)

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: It may be necessary to increase swing arm

tension if changing from a smaller display to a

larger display.

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 11) and
