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.

3.Run Display to fully up, and fully down position and verify proper lift column movement.

4.Repeat steps 1 through 3 until desired lift column movement is achieved.
