Re-handing the Lock (Changing Hand of Locking Piece)

- Locate the locking piece on the lock body.
- Insert a blade screwdriver into the locking piece slot.
- Push the locking piece toward the front of the lock body.
- Rotate the locking piece until the RED indicator shows. This indicates the lock has been re-handed.

Operating Instructions
The Sargent 8200 Series Passage/Closet Mortise Lock is designed for simple and reliable operation.
- To open the door, simply depress the lever handle. The latch bolt will retract with only 30 degrees of rotation.
- Release the lever handle, and the latch bolt will automatically extend, securing the door in the closed position.
- This lock functions as a passage or closet lock, meaning it does not require a key for entry or exit and does not have a locking mechanism.
Maintenance
Regular maintenance ensures the longevity and smooth operation of your Sargent 8200 Series Mortise Lock.
- Cleaning: Clean the exterior surfaces with a soft, damp cloth. Avoid abrasive cleaners or solvents that could damage the finish.
- Lubrication: Periodically apply a small amount of graphite-based lubricant to the latch bolt mechanism to ensure smooth operation. Avoid oil-based lubricants as they can attract dust and debris.
- Fastener Check: Periodically check all mounting screws and fasteners to ensure they are tight. Do not overtighten.
Troubleshooting
If you encounter issues with your Sargent 8200 Series Mortise Lock, consider the following common solutions:
- Lever Sticking or Not Retracting Latch:
- Check for any obstructions around the lever or latch bolt.
- Ensure the mounting screws are not overtightened, which can bind the mechanism.
- Apply lubricant to the latch mechanism as described in the Maintenance section.
- Latch Bolt Not Extending Fully:
- Inspect the strike plate on the door frame for misalignment or debris.
- Ensure the latch bolt is clean and lubricated.
- Loose Lever Handle:
