- Regularly inspect your scooter for any signs of wear, damage, or loose components.
- Be aware of your surroundings and ride responsibly.
- Disclaimer: Please mind potential fire risk and strictly follow the instruction manual for charging and storage of your electric scooter. This fixed block does not affect charging or storage safety.

5. Installation (Setup)
Follow these steps to install the Mast Fixed Block on your Xiaomi electric scooter:
- Prepare the Scooter: Ensure your scooter is turned off and stable. It is recommended to perform this installation on a flat, secure surface.
- Remove Original Folding Mechanism: Carefully loosen and remove all screws securing the original folding mechanism at the base of the scooter's mast. Detach the folding mechanism completely. Keep the original screws and parts in case you wish to revert the modification.
- Position the Fixed Block: Place the new Mast Fixed Block over the scooter's mast, aligning it with the screw holes where the original folding mechanism was attached. The block should fit snugly around the mast.
- Secure the Fixed Block: Insert the provided M5*20 screws into the holes of the fixed block and into the corresponding screw threads on the scooter's mast.
- Tighten Screws: Using the supplied Allen key, gradually tighten all screws. Ensure they are tightened evenly and securely to prevent any movement or slack. Do not overtighten, as this could strip the threads.
- Final Check: Once all screws are tightened, firmly grasp the handlebar and attempt to move the mast. There should be no play or slack. The mast should now be rigidly fixed in an upright position.

6. Operating the Scooter with Fixed Mast
With the Mast Fixed Block installed, your scooter's mast will no longer fold. This modification provides increased stability and eliminates common issues associated with the folding mechanism, such as stem wobble or play. Be aware that the scooter will now be in a permanently upright position, which may affect storage and transport. No special operating procedures are required beyond standard scooter operation.
7. Maintenance
To ensure the longevity and safety of your Mast Fixed Block and scooter:
- Regular Inspection: Periodically check the fixed block and its screws for any signs of loosening, wear, or damage.
- Tighten Screws: If any screws appear loose, retighten them using the Allen key.
- Cleaning: Keep the fixed block clean from dirt and debris. A damp cloth can be used for cleaning. Avoid harsh chemicals.
8. Troubleshooting
- Block does not fit: Ensure you have the correct Mast Fixed Block for your specific Xiaomi scooter model (M365, Pro 2, 1S, Essential, Mi 3 Lite). Double-check the orientation during installation.
- Mast still has slack after installation: Verify that all screws are fully and evenly tightened. If slack persists, remove the block, inspect the scooter's mast for any deformities, and re-install carefully. Ensure no debris is preventing a flush fit.
- Stripped screw head: If a screw head becomes stripped, stop immediately. Do not force it. You may need to use a screw extractor tool or seek professional assistance to remove the screw without damaging the scooter.
9. User Tips
- Consider applying a small amount of thread locker (e.g., Loctite blue) to the screws before tightening to further prevent them from loosening due to vibrations during riding.
- If you frequently transport your scooter in a car or need to store it in compact spaces, remember that this modification removes the folding capability.
- Keep the original folding mechanism and hardware in a safe place in case you ever wish to revert your scooter to its original state.
