3. Setup and Initial Use
3.1. Fitting Your Helmet
- Choose the Correct Size: Ensure the helmet fits snugly around your head without causing pressure points. Your cheeks should be slightly compressed.
- Secure the Retention System: Fasten the chin strap securely. It should be tight enough that you cannot pull the helmet off your head when pulling from the rear.
- Check for Movement: With the strap fastened, try to move the helmet from side to side and up and down. There should be minimal movement.
3.2. Visor Installation/Removal
The main clear visor can be removed for cleaning or replacement. Consult the specific mechanism on your helmet model for detailed instructions. Typically, this involves pressing a release button or lever on each side of the visor pivot point and carefully detaching it.
3.3. Internal Sun Visor Operation
The internal sun visor is operated by a slider located on the side of the helmet. Slide it forward to deploy the sun visor and backward to retract it. Use the sun visor only in bright conditions and ensure it does not obstruct your vision.
4. Operating Your Modular Helmet
4.1. Opening and Closing the Chin Bar
- To Open: Locate the release button or lever, usually positioned at the center front of the chin bar. Press the button and lift the chin bar upwards until it locks into its fully open position.
- To Close: Firmly pull the chin bar downwards until it clicks securely into place. Ensure both sides are fully latched before riding. Warning: Always ride with the chin bar fully closed and latched.
4.2. Ventilation System
Your helmet is equipped with adjustable ventilation vents. These are typically located on the chin bar and top of the helmet. Slide or toggle the vents to open or close them, allowing for airflow adjustment based on riding conditions.
5. Maintenance and Care
5.1. Cleaning the Outer Shell
Use a soft cloth and mild soap with lukewarm water. Avoid harsh chemicals, solvents, or abrasive cleaners, as these can damage the helmet's finish and materials. Rinse thoroughly and air dry.
5.2. Cleaning the Visor
Clean the visor with a soft, damp cloth and mild soap. For stubborn dirt, soak the visor in lukewarm water before gently wiping. Do not use abrasive materials. Allow to air dry completely before re-installing.
5.3. Cleaning the Interior Padding
The interior padding is removable and washable. Hand wash with mild soap and cold water, then air dry completely away from direct sunlight or heat. Ensure padding is fully dry before re-inserting into the helmet.
5.4. Storage
Store your helmet in a cool, dry place away from direct sunlight and extreme temperatures. Do not expose it to chemicals or solvents. Use a helmet bag to protect it from scratches and dust.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Visor fogging | Lack of airflow, cold weather, high humidity. | Open vents, slightly crack the visor, consider anti-fog inserts or sprays. |
| Chin bar not latching securely | Obstruction, worn mechanism, improper closing. | Check for debris, ensure firm closing, inspect latch mechanism for damage. If damaged, seek professional inspection. |
| Excessive wind noise | Improper fit, open vents, worn seals. | Ensure helmet fits snugly, close unnecessary vents, check visor and chin bar seals for damage. |
