2. Installation Instructions

Proper installation of your HJC HJ-09 Flat Anti-Fog Shield is crucial for safety and performance. Always refer to your specific HJC helmet's owner's manual for detailed shield removal and installation procedures, as mechanisms may vary slightly between helmet models.

General Installation Steps:

Prepare Your Helmet: Place your helmet on a stable, flat surface. Ensure the helmet is clean and free of debris around the shield mechanism.
Remove Old Shield (if applicable):
- Open the existing shield to its fully open position.
- Locate the shield release mechanisms on both sides of the helmet. These are typically levers, buttons, or tabs.
- Activate the release mechanism on one side and gently pull the shield away from the helmet. Repeat for the other side.
- Carefully remove the old shield, ensuring not to damage the helmet's shield base plates.
Install New HJ-09 Shield:
- Align the pivot points of the new HJ-09 shield with the shield base plates on your helmet. Ensure the anti-fog side is facing inwards.
- Gently press the shield into place until you hear or feel a click, indicating it is securely seated. Some systems may require you to push a lever back into position.
- Repeat for the other side.
Verify Installation:
- Once installed, slowly open and close the shield several times to ensure it operates smoothly and latches securely in the closed position.
- Check that there are no gaps between the shield and the helmet's eyeport gasket when closed.

3. Operating the Anti-Fog Shield

The HJC HJ-09 Flat Anti-Fog Shield is designed to reduce fogging, particularly in cooler temperatures or high humidity. The anti-fog properties are integrated into the shield material or applied as a coating.

Maximizing Anti-Fog Performance:

Proper Ventilation: Ensure your helmet's ventilation systems are open to allow airflow, which helps to dissipate moisture and maintain the anti-fog effect.
Avoid Touching Inner Surface: Do not touch or wipe the inner surface of the shield, as this can damage the anti-fog coating.
Tear-Offs (Optional): If using tear-offs on the exterior, ensure they are applied correctly to avoid obstructing vision or interfering with shield operation.

4. Maintenance and Care

Proper maintenance extends the life and effectiveness of your HJC HJ-09 Flat Anti-Fog Shield. Always handle the shield with care to prevent scratches or damage to the anti-fog coating.

Cleaning Instructions:

Exterior Cleaning:
- Use a soft, clean cloth (microfiber is recommended) and lukewarm water with a mild soap (e.g., baby shampoo).
- Gently wipe the exterior surface to remove dirt, bugs, and road grime.
- Rinse thoroughly with clean water and air dry, or gently blot with a clean, soft cloth.
- Avoid abrasive cleaners, paper towels, or harsh chemicals, as these can scratch the shield or damage coatings.
Interior (Anti-Fog) Cleaning:
- The anti-fog coating on the interior surface is delicate. Avoid wiping it unless absolutely necessary.
- If cleaning is required, gently dab with a very soft, damp cloth. Do not rub or use any cleaning agents on the interior.
- Allow to air dry completely.

Storage:

When not in use, store the shield in a protective bag or within the helmet to prevent scratches.
Store in a cool, dry place away from direct sunlight or extreme temperatures.
