- The center anti-tip wheel provides additional support, preventing the cabinet from tipping forward when the bottom drawer is fully extended.

Maintenance
Regular maintenance ensures the longevity and smooth operation of your file cabinet.
- Cleaning: Wipe the exterior with a soft, damp cloth and mild detergent. Avoid abrasive cleaners that may damage the scratch-resistant finish.
- Drawer Slides: Periodically check the drawer slides for any debris or obstructions. If drawers become stiff, a small amount of silicone lubricant can be applied to the slides.
- Wheels: Ensure the caster wheels are free of hair or debris that could impede movement. Check that locking mechanisms on the front wheels engage properly.
- Lock: If the lock mechanism feels stiff, apply a small amount of graphite lubricant to the keyhole.
Troubleshooting
- Drawers not opening/closing smoothly: Check for obstructions in the drawer slides. Ensure the cabinet is on a level surface. Lubricate slides if necessary.
- Lock not engaging/disengaging: Ensure all drawers are fully closed before attempting to lock. Check for any bent keys or debris in the keyhole. Lubricate the lock if stiff.
- Cabinet tipping: Ensure the center anti-tip wheel is correctly installed and functioning. Avoid opening multiple drawers simultaneously, especially the bottom drawer, without proper caution.
- Wheels not rolling: Check for debris (e.g., hair, lint) wrapped around the wheel axles. Ensure locking casters are disengaged.
