3.1 Installation Steps
- Remove Old Handle: Rotate the cover plate at the base of your existing window handle to expose the mounting screws. Unscrew these screws and carefully remove the old handle.
- Insert New Handle: Place the new kwmobile handle onto the window frame, ensuring the spindle aligns with the square opening in the window mechanism.
- Secure Handle: Insert the provided olive screws into the mounting holes. Tighten the screws firmly but do not overtighten to avoid damaging the frame.
- Test Functionality: Once secured, test the handle's rotation and locking mechanism to ensure smooth operation.
The handles are designed for quick installation and are compatible with various window materials including plastic, aluminum, and wood.
4. Operating Instructions
The kwmobile lockable window handles allow for both turning and tilting functions, depending on your window type. The integrated lock provides an additional layer of security.
4.1 Opening and Closing
- Closed Position: The handle points downwards.
- Tilted Position: Rotate the handle 90 degrees upwards.
- Open Position: Rotate the handle 180 degrees horizontally.
4.2 Locking and Unlocking
To lock the handle, insert one of the provided keys into the lock cylinder and turn it. This will prevent the handle from being rotated. To unlock, insert the key and turn it in the opposite direction. Remember, all keys are identical, so any key can operate any of the locks.

5. Maintenance
To ensure the longevity and smooth operation of your kwmobile window handles, follow these simple maintenance guidelines:
- Cleaning: Wipe the handles regularly with a soft, damp cloth. Avoid abrasive cleaners or solvents, as these can damage the finish.
- Lubrication: Periodically apply a small amount of silicone-based lubricant to the lock cylinder and the internal mechanism to maintain smooth key operation and handle rotation.
- Check Screws: Occasionally check the mounting screws for tightness. Retighten if necessary to ensure the handle remains securely attached to the window frame.
6. Troubleshooting
6.1 Handle Does Not Fit
If the handle does not fit your window, the most common reason is incorrect spindle length or screw spacing. Please verify the following:
- Spindle Length: The kwmobile handles have a 35 mm spindle length. Measure the spindle length of your original handle.
- Screw Spacing: The screw spacing for these handles is 43 mm. Confirm this measurement on your window frame.
It is recommended to measure your original handles carefully before purchase to ensure compatibility.
6.2 Key Sticks or Lock is Stiff
If the key is difficult to turn or the lock feels stiff, apply a small amount of graphite powder or silicone-based lubricant into the keyhole. Avoid using oil-based lubricants as they can attract dirt and cause further issues.
