NOTE:
If the rack is not leveled properly, you might not be able to install the
stabilizer feet, which are necessary to prevent the rack from tipping over.
1 Using a screwdriver, lower the leveling foot until it rests on the floor.
2 If you need to lower the foot further, tighten the hex nut clockwise with a
12-mm wrench (see Figure 1-8).
3 Repeat steps 1 and 2 for the remaining leveling feet.
4 Ensure that the rack is level.
