2. Setup
2.1 Setting the Combination Lock
Your Samsonite Focus III Attache is equipped with a three-digit combination lock for enhanced security. Follow these steps to set your personal combination:
- Ensure the lock is currently set to the factory default combination (usually 0-0-0).
- Locate the small reset button or lever on the side or bottom of the lock mechanism. This may require a pen tip or a small pointed object to press.
- While pressing the reset button/lever, rotate the number dials to your desired three-digit combination. Choose a memorable but secure combination.
- Release the reset button/lever. Your new combination is now set.
- Important: Test your new combination by scrambling the dials and then entering your set code to open the attache. Do not forget your combination.

3. Operating the Attache
3.1 Opening and Closing
To open the attache, ensure the combination locks are set to the correct code, then slide the latch releases outwards. The lid will open, sometimes partially due to the patented hinge design, or fully when laid flat.
To close, align the lid with the base and press down firmly until the latches click into place. Scramble the combination dials to secure the attache.
3.2 Utilizing Internal Compartments
The Focus III Attache features multiple organizational compartments designed to keep your items secure and accessible.
- Document Holders: The lid interior includes expandable file pouches for documents, folders, and papers.
- Accessory Pockets: Smaller pockets are available for pens, business cards, small electronics, and other essentials.
- Main Compartment: The spacious main compartment is ideal for larger items such as laptops, notebooks, and bulkier documents.

4. Maintenance
4.1 Cleaning
To maintain the appearance of your ABS hardside attache, wipe the exterior with a soft, damp cloth. For stubborn marks, a mild soap solution can be used, followed by wiping with a clean, damp cloth and drying thoroughly. Avoid abrasive cleaners or solvents, as these can damage the finish.
4.2 Lock Care
Periodically check the combination lock mechanisms for smooth operation. If they become stiff, a small amount of silicone-based lubricant can be applied to the moving parts. Do not force the lock if it is jammed.
5. Troubleshooting
5.1 Combination Lock Issues
- Lock will not open: Double-check that the correct three-digit combination is entered. Ensure each number is precisely aligned in the center of the display. If you have forgotten your combination, contact Samsonite customer support for assistance.
- Lock feels stiff: Apply a small amount of silicone lubricant to the dials and the latch mechanism. Work the dials and latches several times to distribute the lubricant.
5.2 Hinge Operation
- Lid does not open fully: The patented hinge is designed to open partially when upright. To open fully, lay the attache flat on a stable surface before releasing the latches.
