5. Operating Instructions
5.1 Using the Combination Lock
Your KAER locker is equipped with a combination lock for security. The initial combination is typically set to a default (e.g., 0-0-0). Please refer to the specific lock instructions provided in your package for detailed steps on setting and resetting your personal combination.
- Opening the Lock: Dial the correct three-digit combination to the indicator line. Turn the handle to open the door.
- Setting a New Combination: With the lock open, locate the reset button or lever (often on the inside edge of the lock mechanism). Use the provided key to press or move the reset mechanism. While holding it, set your desired new three-digit combination. Release the reset mechanism. Test your new combination before closing the door.
- Closing the Lock: Close the door and scramble the combination dials to secure the locker.
5.2 General Use
- Door Operation: Gently open and close the locker door. Avoid slamming to prevent damage to the hinges and lock mechanism.
- Ventilation: The locker features ventilation holes to allow for air circulation.
- Business Card Holder: A dedicated slot is available on the door for a business card or label.

6. Maintenance
- Cleaning: Wipe the exterior and interior surfaces with a soft, damp cloth. Avoid using abrasive cleaners, solvents, or harsh chemicals, as these can damage the finish.
- Inspection: Periodically check all screws, bolts, and connections to ensure they remain tight. Retighten if necessary.
- Lock Care: Keep the lock mechanism clean and free of dust. Do not force the lock if it feels stiff; apply a small amount of graphite lubricant if needed.
7. Troubleshooting
- Door Not Closing Properly: Check for any obstructions inside the locker or around the door frame. Ensure the cabinet is level and not warped. Verify hinges are properly aligned and tightened.
- Combination Lock Not Working: Double-check that you are dialing the correct combination. If you have forgotten the combination, use the reset key and follow the instructions for resetting the code. Ensure the dials are fully aligned with the indicator.
- Cabinet Feels Unstable: Confirm that the cabinet is placed on a flat, level surface. Ensure the wall anchor kit is properly installed and securely fastened to a sturdy wall stud or appropriate wall anchor.
