Operation
Opening the Lock Box
- Slide down the protective shutter to reveal the combination dials.
- Rotate the dials to your set 4-digit combination.
- Pull the cover of the lock box outwards to open it. The U-shaped spring will assist in opening.
Closing and Securing the Lock Box
- Place your keys or other items inside the compartment.
- Close the cover firmly until it latches.
- Scramble the combination dials to lock the box and prevent unauthorized access.
- Slide up the protective shutter to cover the dials and protect them from elements.
Maintenance
- Regular Cleaning: Wipe the exterior with a soft, damp cloth to remove dust and grime. Avoid abrasive cleaners.
- Combination Dials: Periodically check that the dials rotate smoothly. If they become stiff, a small amount of graphite lubricant can be applied.
- Weather Protection: Ensure the protective shutter is always closed when not in use to shield the dials from weather conditions. The included rubber plugs for the wall-mount holes help prevent water seepage.
- Inspection: Regularly inspect the lock box and shackle for any signs of wear or damage.
