5. Operating Instructions
The HIEMEY BS-008N is a passage function door knob. This means it is designed for doors that do not require a locking mechanism, such as hallway doors, closet doors, or pantry doors. The knobs will turn freely from both sides, operating the latch to open and close the door.
Basic Operation:
- To open the door, simply turn either crystal knob in either direction. The latch bolt will retract, allowing the door to open.
- To close the door, push the door shut. The spring-loaded latch bolt will automatically retract when it meets the strike plate and then extend into the strike plate hole, securing the door in the closed position.

6. Maintenance
To ensure the longevity and appearance of your HIEMEY Glass Crystal Passage Door Knob, follow these simple maintenance guidelines:
- Cleaning: Use a soft, damp cloth to wipe down the crystal knobs and brass rosettes. Avoid abrasive cleaners, harsh chemicals, or solvents, as these can damage the finish and crystal.
- Lubrication: Periodically, a small amount of silicone-based lubricant can be applied to the latch mechanism to ensure smooth operation. Do not use oil-based lubricants, as they can attract dust and debris.
- Tightening: Over time, screws may loosen. Periodically check and gently tighten any loose screws on the rosettes or strike plate to maintain stability.
7. Troubleshooting
If you encounter any issues with your HIEMEY BS-008N door knob, consider the following common troubleshooting steps:
- Knob is Loose: Check the set screws on the knob and the mounting screws on the rosette. Tighten them gently with the provided hex key or a screwdriver.
- Latch Not Retracting/Extending Smoothly: Ensure the latch mechanism is properly aligned within the door bore. Apply a small amount of silicone lubricant to the moving parts of the latch. Check for any obstructions in the door frame's strike plate opening.
- Door Not Latching: Verify that the strike plate on the door frame is correctly aligned with the latch bolt. Adjust the strike plate position if necessary.
- Difficulty Turning Knob: Ensure no debris is obstructing the mechanism. If the issue persists after lubrication and checking for obstructions, the internal mechanism may require inspection.
