4. Setup
4.1 Proper Helmet Fit
A properly fitting helmet is crucial for safety. The helmet should fit snugly around your head without causing pressure points. It should not move freely when you shake your head. The cheek pads should press firmly against your cheeks. If the helmet feels loose or can be easily rotated, it is too large.
4.2 Chin Strap Fastening
Always secure the chin strap firmly. The strap should be tight enough so that the helmet cannot be pulled off your head, but not so tight as to cause discomfort. Ensure the quick-release buckle is fully engaged.
4.3 Visor Adjustment
The clear outer visor can be opened and closed. Ensure it latches securely in the closed position to prevent accidental opening during riding. The integrated sunshield is operated by a lever, typically located on the side of the helmet, allowing it to be deployed or retracted as needed for varying light conditions.
5. Operating Instructions
5.1 Clear Visor Operation
To open the clear visor, lift it from the bottom edge. It can be set in various open positions or fully closed. To close, push the visor down until it clicks into place.
5.2 Integrated Sunshield Operation
Locate the lever on the side of the helmet. Push the lever forward or backward to deploy or retract the internal sunshield. Use the sunshield to reduce glare in bright conditions. Do not use the sunshield in low light or at night.
5.3 Ventilation System
The HJC i30 features top vents and rear exhaust vents. These vents can be opened or closed to control airflow through the helmet. Adjust the top vents by sliding the controls to increase or decrease ventilation. Proper ventilation helps to reduce heat and fogging inside the helmet.
6. Maintenance
6.1 Exterior Cleaning
Clean the helmet's exterior with a soft cloth, warm water, and mild soap. Avoid abrasive cleaners, solvents, or petroleum-based products, as these can damage the shell material and finish. Rinse thoroughly and dry with a soft, clean cloth.
6.2 Visor Care
Clean the clear outer visor and integrated sunshield with warm water and a soft cloth. For stubborn dirt, use a helmet-specific visor cleaner. Avoid wiping a dry or dirty visor, as this can cause scratches. Replace scratched visors immediately as they can impair vision.
6.3 Liner Removal and Washing
The interior lining and cheek pads are removable for cleaning. Carefully detach them by unsnapping or unhooking them from the helmet shell. Hand wash the liner and pads in cool water with a mild detergent. Allow them to air dry completely before reinserting them into the helmet. Ensure all components are securely reattached before use.
7. Troubleshooting
7.1 Visor Fogging
If your visor fogs up, ensure the ventilation system is open to allow maximum airflow. Slightly opening the visor to the first detent can also help to clear fog. Anti-fog treatments or pinlock inserts (if compatible) can further reduce fogging.
7.2 Discomfort or Pressure Points
If you experience discomfort or pressure points, re-evaluate the helmet's fit. While some break-in is normal, persistent discomfort may indicate an incorrect size. Ensure the liner and cheek pads are correctly seated. If issues persist, consult a helmet fitting specialist.
