Pull the drawer open.
Locate the two locking devices on the left and right sides of the drawer bottom, against the drawer front. Run a finger along the bottom of each locking device until it falls into the recessed adjustment tab along the outer edge of each device.
Pull both fingers toward the bottom of the drawer to release the tabs. Hold the tabs in their release positions. Push the tabs toward the cabinet to raise the drawer front or pull them forward to lower the drawer front.
Close the drawer. Repeat the steps if the drawer does not fully close. Note the orientation of the drawer front to the cabinet face.
Open the drawer. Wrap the fingers of both hands around the sides of the drawer with their tips resting on the inside edge of each locking device. Pull your fingers toward the outside of the drawer to release the closures from the cabinet-mounted slides.
Turn the tilt adjustment levers -- mounted at the rear sides of the drawer -- counterclockwise to tilt the drawer front forward, clockwise to tilt the drawer front backward. Push the drawer into the slides. Close the drawer.
