HJC i50 Off-Road Helmet User Manual

1. Introduction

Welcome to the user manual for your HJC i50 Off-Road Helmet. This manual provides essential information for the proper use, maintenance, and care of your helmet. Please read it thoroughly before using your helmet to ensure maximum safety and to understand its features. Proper use and maintenance will extend the life of your helmet and ensure its protective capabilities.

2. Safety Information

Your HJC i50 helmet is designed to provide protection during off-road motorcycling activities. Adherence to safety guidelines is crucial.

• DOT Certification: This helmet is DOT certified, meeting or exceeding FMVSS-218 and DOT safety standards. This certification indicates that the helmet has passed rigorous testing for impact absorption and penetration resistance.
• Proper Fit: A helmet must fit snugly and securely to provide optimal protection. Refer to the 'Setup' section for fitting instructions.
• Impact Protection: The helmet is designed to absorb the energy of an impact by partial destruction of the shell and liner. Even if damage is not visible, a helmet that has sustained an impact should be replaced.
• Proposition 65 Warning: This product may contain chemicals known to the State of California to cause cancer and birth defects or other reproductive harm.
• Visibility: Always ensure your helmet's peak is properly adjusted for clear vision.

3. Setup and Initial Use

Before your first ride, ensure your helmet is correctly fitted and adjusted.

1. Sizing and Fit:
   • Measure your head circumference to determine the correct size.
   • The helmet should feel snug around your head, cheeks, and jaw.
   • When you try to move the helmet from side to side or front to back, your skin should move with the helmet. If the helmet slides independently, it is too large.
   • There should be no pressure points that cause discomfort.
2. Strap Adjustment:
   • Fasten the chin strap securely. The strap should be tight enough that you cannot remove the helmet by pulling it forward or backward.
   • Ensure the strap does not pinch your throat.
3. Peak Adjustment:
   • The helmet features an adjustable peak. Loosen the screws on either side of the peak and the top screw to adjust its angle.
   • Position the peak to block sun glare and roost while maintaining an unobstructed field of vision.
   • Tighten all screws firmly after adjustment.

4. Operating Features

Understand the key technologies and features integrated into your HJC i50 helmet.

• SLID (Sliding Layer Impact Distribution): This technology is designed to reduce rotational forces during an impact. It allows for a sliding motion between layers, helping to dissipate energy more effectively.
• SuperCool Interior Lining: The interior lining is made from a moisture-wicking, antibacterial fabric that provides enhanced comfort. It is designed to keep you cool and dry during rides.
• Large Eye Port: The helmet features a generously sized eye port to accommodate various goggle types and provide a wide field of view, essential for off-road riding.
• ACS Advanced Channeling Ventilation System: This system utilizes front-to-back airflow to flush heat and humidity up and out of the helmet. Ensure all vents are clear of obstructions for optimal performance.

5. Maintenance and Care

Regular maintenance ensures the longevity and effectiveness of your helmet.

1. Exterior Cleaning:
   • Clean the helmet shell with a soft cloth, mild soap, and lukewarm water.
   • Avoid harsh chemicals, solvents, or abrasive cleaners, as these can damage the helmet's finish and materials.
   • Rinse thoroughly and dry with a soft, clean cloth.
2. Interior Lining Cleaning:
   • The SuperCool interior lining is removable for cleaning. Carefully detach the cheek pads and comfort liner.
   • Hand wash the lining in cold water with mild soap. Do not machine wash or tumble dry.
   • Allow the lining to air dry completely before reinserting it into the helmet.
3. Strap Cleaning:
   • Clean the chin strap with mild soap and water.
   • Allow it to air dry completely.
4. Storage:
   • Store your helmet in a cool, dry place, away from direct sunlight and extreme temperatures.
   • Avoid storing it near chemicals or solvents that could degrade the helmet materials.
5. Inspection:
   • Regularly inspect the helmet for any signs of damage, such as cracks in the shell, frayed straps, or degraded interior components.
   • If any damage is found, discontinue use and consider replacement.

6. Troubleshooting

This section addresses common issues you might encounter.

• Helmet feels too tight or loose: Re-evaluate your head measurement and compare it with HJC's sizing chart. Ensure the chin strap is properly adjusted. If discomfort persists or the helmet moves excessively, you may need a different size.
• Poor ventilation: Check if all intake and exhaust vents are open and free from obstructions (e.g., dirt, debris). Ensure the interior lining is clean and properly installed.
• Discomfort from interior: Ensure the SuperCool lining is correctly seated and not bunched up. If new, allow for a break-in period. If discomfort persists, consult with a helmet specialist.
• Peak feels loose: Tighten the peak attachment screws. Do not overtighten.
