- Wellnuts: Tighten only 2.5 revolutions after the bolt touches the washer to avoid damaging the roof.
Assembly and Installation
The installation process involves several key phases:


1. Preparation and Removal
Remove the original windshield, mounting hardware, and rear-view mirrors. Remove the upper handle cover, rear cover, front upper panel, and upper leg shield as required for access.
2. Drilling and Frame Assembly
Use a hole saw to create necessary openings in the front upper panel (32mm) and rear cover (21mm). Assemble the front frame by installing mirror brackets, the main harness earth wire, and the motor.
3. Mounting the Roof and Screen
Install the rear frame and rear deck. Secure the roof outer and inner parts to the rear frame using wellnuts and washers. Attach the front screen to the roof and front frame, ensuring the wellnuts are tightened correctly.
4. Final Components
Install the mirrors, wiper system, and front inner cover. Connect the switch harness and main harness. Perform an operations check to ensure the wiper functions correctly and the accessory terminal is properly connected and waterproofed.
Maintenance and Cleaning
To maintain the front screen and roof:
- Keep the screen clean to ensure visibility.
- Use a soft cloth or sponge with diluted neutral detergent for cleaning.
- Avoid using organic solvents, strong detergents, or high-pressure washers, as these can damage the materials.
- Avoid parking in direct sunlight to prevent heat-related deformation.
