Leveling the Library

3

Completing this task requires leveling one side of the library at a time, 
moving in a clockwise direction from the front to the right side. To do 
this:

1 Move the library into its final position for installation.

Make sure you leave enough floor space around the library for 
removing cosmetic panels, attaching cables, opening the front 
door, and so on. For minimum floor space dimensions, refer to 
figure 4 on page 3.

2 Lower each foot of the library until it makes contact with the floor.

When adjusting the feet for leveling purposes, do not raise 
any foot so high that excess weight is transferred to any 
single caster.

3 Starting at the front of the library and moving from foot to foot in a 

clockwise direction, rotate each foot clockwise so the 
corresponding caster is raised approximately

 inch off the floor.

4 Place the carpenter’s level on top of the front edge of the library.

5 Check the gauge on the level. If the front of the library is level, 

proceed to step 6. If it is not level:

a

Determine the tilt of the library and adjust the appropriate foot 
with the wrench, checking the gauge each time any foot is 
rotated

 turn.

b

Repeat step 5 until the front is level.

6 Repeat steps 4 and 5 to level the left side, the back side, and the 

right side of the library.

7 Check each side again as follows:

a

Starting at the front of the library, place the level on top of each 
edge (front, left, back, and right) and check the gauge. 

b

Make any minor adjustments necessary to the feet to make the 
side level. 

8 Repeat step 7 until all four sides are level.
