2. Safety Instructions
- Do not force the lock mechanism. If the combination is forgotten, professional assistance may be required to open the box without damage.
- Keep the combination confidential and store it in a safe place, separate from the document box.
- Ensure the box is closed and locked when transporting or storing valuable items.
- Avoid exposing the box to extreme temperatures or harsh chemicals, which could damage the finish or internal components.
3. Setup: Setting the Combination Lock
The HMF 1413-07 document box comes with a pre-set combination, usually "0-0-0". Follow these steps to set your personal combination:
- Open the Box: Ensure the lock is set to the current combination (factory default is "0-0-0"). Push the release button or slide the latch to open the box.
- Locate the Reset Lever/Button: Inside the open box, usually on the back of the lock mechanism, you will find a small lever or button. Push this lever to the "SET" position or press the button firmly.
- Set Your New Combination: While the reset lever/button is engaged, rotate the three number dials to your desired personal combination. Choose a memorable sequence.
- Confirm New Combination: Return the reset lever/button to its original position (e.g., "OFF" or released). Your new combination is now set.
- Test the Lock: Scramble the dials. Then, enter your new combination and attempt to open the box to ensure it works correctly.
Important: Do not forget your new combination. There is no master key or override for this type of lock. If the combination is lost, the box may need to be forced open, potentially causing damage.

4. Operating the Document Box
4.1 Opening the Box
- Rotate the three number dials to your set combination.

- The lid will spring open slightly, allowing you to fully open the box.
4.2 Closing and Locking the Box

4.3 Using the Folding Handle
The document box is equipped with a folding handle for easy portability. To use, simply lift the handle from its recessed position. When not in use, the handle can be folded flat against the side of the box for compact storage.

5. Maintenance
To ensure the longevity and proper function of your HMF document box, follow these maintenance guidelines:
- Cleaning: Wipe the exterior with a soft, damp cloth. Avoid abrasive cleaners or solvents, which can damage the powder-coated finish.
- Lock Mechanism: The combination lock is generally maintenance-free. If the dials become stiff, a small amount of graphite powder (not oil) can be applied to the mechanism.
- Storage: Store the box in a dry environment to prevent rust or corrosion.
6. Troubleshooting
6.1 Lock Not Opening
- Incorrect Combination: Double-check that you have entered the correct three-digit combination. Ensure each number is precisely aligned in the center of the viewing window.
- Dials Not Aligned: Sometimes the dials may not be perfectly aligned. Gently wiggle each dial to ensure it's fully seated on the correct number.
- Stuck Mechanism: If the lock feels stiff, try applying slight pressure to the lid while entering the combination and pressing the release button.
6.2 Forgotten Combination
If you have forgotten your combination, there is no simple way to reset it without knowing the current combination. The manufacturer does not provide a master key or override code for this type of lock. In such cases, professional locksmith services may be required, or the box may need to be opened by force, which could result in damage to the product.
