2. Safety Information

• Always ensure the lock is installed securely according to these instructions. Improper installation may compromise security.
• Keep keys in a safe place, away from the window, and out of reach of children.
• Regularly check the lock for signs of wear or damage. Do not use if damaged.
• This lock is designed for additional security and should not replace primary window locking mechanisms.
• When drilling, wear appropriate safety gear (e.g., eye protection) and ensure no electrical wires or pipes are present behind the drilling surface.

3. Package Contents

The ABUS FTS88 Window Lock package typically includes:

• 1x ABUS FTS88 Window Lock unit
• 2x Keys (for keyed-alike models, all locks with the same AL code use the same key)
• Mounting screws
• Spacers (if required for installation)

4. Setup and Installation

The ABUS FTS88 is designed for easy installation on most plastic or aluminum windows and doors. The lock box mounts on the window casement, and the strike plate mounts on the window frame.

Tools Required:

• Drill
• Drill bits appropriate for your window frame material
• Screwdriver
• Pencil
• Measuring tape

Installation Steps:

1. Positioning the Lock: Close the window or door. Hold the main lock unit (with the key cylinder) against the window casement and the strike plate against the window frame. Ensure they are aligned so the lock claws can engage properly when extended. The narrow design allows for installation in confined spaces.
2. Marking Drill Holes: Once the optimal position is determined, use a pencil to mark the screw holes for both the main lock unit and the strike plate. Refer to the dimension diagram for precise measurements and clearances.

3. Drilling Pilot Holes: Drill pilot holes at the marked positions. Use a drill bit suitable for your window material (e.g., smaller diameter for plastic/aluminum to prevent cracking).
4. Mounting the Main Lock Unit: Secure the main lock unit to the window casement using the provided screws. Ensure it is firmly attached.
5. Mounting the Strike Plate: Secure the strike plate to the window frame using the provided screws. Test the lock mechanism before fully tightening to ensure smooth operation. If necessary, use the included spacers to achieve proper alignment and engagement of the lock claws.
6. Final Check: With the window closed, insert the key and turn it to engage the lock. The steel claws should extend and firmly grip the strike plate. Turn the key back to disengage. Ensure smooth operation without excessive force.

5. Operating Instructions

The ABUS FTS88 Window Lock is operated using the supplied key.

• To Lock: Close the window or door completely. Insert the key into the cylinder and turn it clockwise until the steel claws are fully extended and engaged with the strike plate. Remove the key. The window is now secured.
• To Unlock: Insert the key into the cylinder and turn it counter-clockwise until the steel claws retract fully. The window can now be opened.

Keyed-Alike Functionality: If you have multiple ABUS FTS88 locks with the same "AL" code (e.g., AL0145), a single key can operate all of them. This provides convenience by reducing the number of keys required for multiple security points.

6. Maintenance

To ensure the longevity and smooth operation of your ABUS FTS88 Window Lock, follow these maintenance guidelines:

• Cleaning: Clean the exterior of the lock with a soft, damp cloth. Avoid abrasive cleaners or solvents, as these can damage the finish.
• Lubrication: Periodically (e.g., once a year or if operation becomes stiff), apply a small amount of graphite-based lubricant or a specialized lock lubricant into the key cylinder and onto the moving parts of the locking mechanism. Avoid oil-based lubricants, which can attract dust and grime.
• Inspection: Regularly inspect the lock and its mounting screws for any signs of loosening, wear, or damage. Tighten screws if necessary. If any part is significantly damaged, consider replacing the unit.

7. Troubleshooting

If you encounter issues with your ABUS FTS88 Window Lock, refer to the following common problems and solutions:

• Key is difficult to turn or mechanism feels stiff:
  • Ensure the key is fully inserted.
  • Apply a small amount of graphite-based lock lubricant into the key cylinder.
  • Check if the window is fully closed and not putting pressure on the lock mechanism.
• Lock claws do not engage the strike plate:
  • Verify that the window is completely closed and latched.
  • Check the alignment of the main lock unit and the strike plate. Adjust if necessary, using spacers if there is a gap.
  • Inspect for any obstructions preventing the claws from extending fully.
• Lock appears loose on the window:
  • Tighten all mounting screws. Do not overtighten.
  • If the mounting surface is damaged, consider professional repair or relocation of the lock if possible.

If problems persist after attempting these solutions, please contact ABUS customer support.
