Leveling the Cabinet
Once all the components of the cabinet have been installed, level the cabinet. The following section is a
step-by- step illustration of the process of leveling the cabinet.
1.
Place the cabinet at the desired location (preferably an open ground). Use a movable wrench to
loosen the fixing nuts on the four foot bolts in a clockwise direction.
2.
Rotate the hexagonal bolts at the bottom of the feet in the clockwise or counterclockwise direction
until the feet rise or fall to a suitable position. Use a gradient measuring tool to ensure that the cabinet
is in a uniform level state. Refer to the Figure 3-10 to understand the process better.
