• Rinse thoroughly with clean water and allow it to air dry completely before storage or next use.
• The internal padding can often be removed for separate cleaning; refer to manufacturer instructions for specific details.

6.2. Inspection

Perform a thorough inspection before and after each use:

• Check the outer shell for cracks, deep scratches, dents, or discoloration.
• Examine the chin strap and adjustment system for fraying, cuts, or damage to buckles and mechanisms.

7. Troubleshooting

This section addresses common issues you might encounter with your Irudek OREKA II Vent helmet.

7.1. Helmet Feels Loose or Unstable

• Solution: Re-adjust the ROUNDFIT system by turning the rear dial clockwise until a snug fit is achieved. Ensure the chin strap is also tightened appropriately.
