5. Operating Instructions
Your HPDMC Garage Storage Cabinet System is designed for efficient tool and item organization.
5.1. Using Cabinets and Drawers

- Locking Mechanism: Use the provided steel keys to lock cabinets and drawers for secure storage of valuable items.
5.2. Workbench Use
- The 52-inch workbench provides a stable surface for various tasks. Ensure the workbench is clear of clutter before beginning work.
- Avoid placing excessively heavy objects on the workbench that could compromise its stability or structural integrity.
5.3. Pegboard Organization
- The pegboards are ideal for hanging frequently used tools. Arrange hooks and accessories to suit your specific needs.
- Ensure tools are securely placed on hooks to prevent them from falling.

6. Maintenance
Regular maintenance will prolong the life and appearance of your storage system.
- Cleaning: Wipe down all surfaces with a soft, damp cloth and mild detergent. Avoid abrasive cleaners that can damage the finish.
- Inspection: Periodically check all fasteners (screws, bolts) to ensure they remain tight. Re-tighten as necessary.
- Drawer Slides: For smooth operation, occasionally apply a silicone-based lubricant to the drawer slides.
- Casters: Inspect casters on roller cabinets for debris and ensure they rotate freely. Clean as needed.
- Rust Prevention: The cold-rolled steel construction includes rust and corrosion prevention layers. However, avoid prolonged exposure to excessive moisture.

7. Troubleshooting
Refer to this section for solutions to common issues.
- Wobbly Cabinets: Ensure all assembly hardware is tightened. If wall-mounted, verify secure attachment to wall studs or appropriate anchors. Adjust leveling feet if applicable.
- Sticking Drawers: Check for obstructions in the drawer slides. Clean any debris and apply a silicone lubricant. Ensure drawers are not overloaded.
- Doors Not Closing Properly: Verify that the cabinet is level. Check hinges for proper alignment and tightness. Ensure nothing is obstructing the door's path.
- Keys Not Working: Ensure the key is fully inserted and turned correctly. Do not force the key. If the lock is stiff, a small amount of graphite lubricant may help.
