5. Maintenance and Care
5.1 Cleaning
- Wipe surfaces with a soft, damp cloth.
- Avoid abrasive cleaners or harsh chemicals, as these can damage the finish.
- Promptly clean up spills to prevent staining or water damage.
5.2 General Care
- Periodically check all screws and fasteners to ensure they remain tight.
- Avoid exposing the cabinet to direct sunlight or extreme temperature changes, which can cause warping or fading.
- Do not place hot items directly on the surface without protection.
6. Troubleshooting
- Difficulty during assembly: Ensure all parts are correctly oriented according to the diagrams. Do not force screws; if resistance is met, re-check alignment. A power drill can assist but use low torque settings.
- Drawers not closing smoothly: Check that drawer slides are correctly installed and aligned on both the drawer and the cabinet frame. Ensure no obstructions are in the drawer path.
- Cabinet feels unstable: Verify that all casters are securely attached and that the front casters' brakes are engaged when stationary. Ensure weight is evenly distributed.
- Lock not working: Confirm the lock mechanism is fully installed. Note that the lock typically secures only the top drawer.
