5. Operating Instructions
Using the Drawers:
To open a drawer, gently pull the handle. The drawers are designed for full extension, allowing you to pull them out completely to access files at the back. To close, push the drawer firmly until it is fully seated. The smooth slide rails ensure quiet operation.

Locking Mechanism:
The top drawer features a central locking mechanism that secures all four drawers simultaneously. Insert the key into the lock on the top drawer and turn it to lock or unlock the cabinet. Ensure all drawers are fully closed before attempting to lock the cabinet.
Anti-Tip Interlock System:
This safety feature prevents more than one drawer from being opened at a time. If one drawer is open, the others will remain locked. This design significantly reduces the risk of the cabinet tipping forward, especially when drawers are heavily loaded. Do not attempt to force multiple drawers open simultaneously.

6. Maintenance and Care
Proper maintenance will ensure the longevity and optimal performance of your SISESOL file cabinet.
- Cleaning: Wipe the exterior surfaces with a soft, damp cloth. Avoid abrasive cleaners or harsh chemicals that could damage the finish. The metal construction and electrostatic spraying make it easy to clean.
- Drawer Rails: Periodically check the drawer slide rails for any debris or obstructions. If drawers do not glide smoothly, clean the rails and apply a small amount of silicone lubricant if necessary.
- Lock Mechanism: Keep the lock mechanism clean and free of dust. Do not force the key if it feels stiff; a small amount of graphite lubricant can be applied if needed.
- Stability: Regularly check that the cabinet is stable and all feet are firmly on the ground.
- Rust Prevention: The cabinet features anti-rust electrostatic spraying. Avoid prolonged exposure to moisture to maintain this protection.
