Lift Column Bearing Adjustment

The upper and lower lift columns are aligned using two lift
bearings, one upper and one lower.
Bearing adjustment is pre-set at the factory, however, there may
be times when it is required to make slight adjustments in
bearing tightness to eliminate excess play in lift columns or
noise.
WARNING:
OVERTENSIONING CAN LEAD TO DAMAGE
TO EQUIPMENT! DO NOT overadjust!
IMPORTANT ! :
Display should be installed on mount prior to
performing lift colimn bearing adjustment!
To adjust lift column bearings:
1. Determine if it is the upper or lower lift column that requires
adjustment.
2. Using a hex wrench, turning in small increments evenly
across all adjustment screws, loosen or tighten adjustment
screws. (See Figure 28)
3. Run display to fully up, and fully down positions and verify
proper lift column movement.
4. Repeat Steps 1 through 3 until desired lift column
movement is achieved.
