CM2C40 Installation Instructions

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 column 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 lift 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.
