8.3.8 Leveling Cabinets
I. Moving the cabinets to the position
Lift the cabinets on the slide rails, and align centers of the cabinet feet with the centers of the
troughs on the slide rails vertically. Align all cabinets.
II. Leveling the cabinets
Follow these steps to level the cabinets as shown in Figure 8-32.
1) Unfasten the retaining nuts of the cabinets;
2) Place a horizontal ruler in the two orthogonal directions on the top of the cabinets
to check levelness.
3) If the cabinets are not flush, unfasten the retaining nuts of the cabinets on the
feet with a spanner, and then rotate the screw bolts on the feet to adjust the
height of the cabinets until they are flush.
