Read all instructions carefully before installation and use. Failure to follow these instructions may result in property damage or injury. Keep keys in a safe place away from children.

• Consult a qualified professional if you are unsure about any installation steps.

3. Setup and Installation

This section outlines the general steps for installing the L-handle lock. Specific installation may vary based on your garage door type. Ensure you have appropriate tools such as a drill, screwdriver, and measuring tape.

1. Prepare the Door: If replacing an existing lock, remove the old hardware. Clean the area where the new lock will be installed.
2. Position the L-Handle: Place the L-handle assembly on the exterior of the garage door at the desired locking point. Ensure it aligns with the internal locking mechanism (not included).
3. Mark and Drill: Mark the positions for the mounting screws and the spindle hole. Carefully drill pilot holes for the screws and the main spindle opening, ensuring they are appropriately sized for the hardware.
4. Install the Spindle: Insert the square spindle (if applicable) through the door and into the L-handle mechanism.
5. Secure the Handle: Attach the L-handle assembly to the door using the provided screws. Ensure it is firmly secured but do not overtighten.
6. Test Operation: Insert a key into the lock cylinder and turn it to ensure smooth operation. Verify that the L-handle rotates freely and engages the internal locking mechanism correctly.

4. Operating Instructions

The L-handle lock is designed for straightforward operation.

• To Lock: Insert the key into the lock cylinder. Turn the key clockwise (or counter-clockwise, depending on installation) to engage the internal locking mechanism. Remove the key. The L-handle should now be fixed in position, preventing the door from opening.
• To Unlock: Insert the key into the lock cylinder. Turn the key counter-clockwise (or clockwise) to disengage the internal locking mechanism. Remove the key. The L-handle should now be free to rotate, allowing the door to be opened.

5. Maintenance

Regular maintenance will ensure the longevity and smooth operation of your lock.

• Cleaning: Periodically wipe the exterior of the L-handle with a soft, damp cloth to remove dirt and grime. Avoid abrasive cleaners.
• Lubrication: Apply a small amount of graphite lubricant or a silicone-based spray lubricant into the keyway and moving parts of the lock cylinder once or twice a year. Do not use oil-based lubricants as they can attract dirt.
• Inspection: Regularly check for any signs of wear, corrosion, or loose screws. Tighten screws as needed. If significant wear or damage is observed, consider replacing the unit.

6. Troubleshooting

If you encounter issues with your L-handle lock, try the following solutions:

• Key is difficult to insert or turn:
  Solution: Apply graphite lubricant to the key and insert it into the keyway several times. Wiggle gently. Ensure the key is fully inserted. Check for any debris in the keyway.
• L-handle is stiff or not rotating smoothly:
  Solution: Lubricate the moving parts of the handle mechanism with a silicone-based spray. Check for any obstructions or bent components. Ensure mounting screws are not overtightened.
• Lock does not engage/disengage:
  Solution: Verify that the internal locking mechanism (not part of this product) is properly aligned and functioning. Ensure the spindle is correctly seated in both the L-handle and the internal mechanism.
• Keys are lost:
  Solution: If all keys are lost, the lock cylinder will need to be replaced by a locksmith or a new L-handle assembly purchased.
