2. Setup and Initial Adjustment

2.2 Adjusting the Fit System
For optimal safety and comfort, the helmet must fit snugly and securely. The Predator helmet features a rear dial adjustment system.
- Place the helmet on your head, ensuring it sits level and covers your forehead.
- Rotate the dial located at the back of the helmet clockwise to tighten the fit, or counter-clockwise to loosen it. Adjust until the helmet feels snug without causing discomfort.
- Adjust the side straps so they form a 'V' shape just below your ears.
- Fasten the chin buckle and tighten the strap until it is snug under your chin, allowing only one or two fingers to fit between the strap and your chin.

3. Operating Instructions
3.1 Wearing the Helmet Correctly
Always wear your helmet correctly to maximize its protective capabilities. The helmet should sit level on your head, covering your forehead. It should not be tilted back, exposing your forehead, or tilted forward, obstructing your vision.
3.2 Securing the Chin Strap
After placing the helmet and adjusting the rear dial, ensure the chin strap is properly secured. The buckle should be centered under your chin, and the strap should be tight enough that the helmet does not move excessively when you shake your head, but not so tight as to cause discomfort or restrict breathing.

4. Maintenance
4.1 Cleaning the Helmet Shell
To clean the exterior of your helmet, use a soft cloth dampened with mild soap and water. Avoid harsh chemicals, abrasive cleaners, or solvents, as these can damage the helmet's finish and materials. Rinse thoroughly and air dry.
4.2 Cleaning the Inner Pads
The inner pads of your ZOL Predator helmet are removable and washable. Gently detach the pads from the helmet. Hand wash them with mild soap and cool water. Allow them to air dry completely before reattaching them to the helmet. Ensure they are correctly positioned for comfort and fit.

Store your helmet in a cool, dry place away from direct sunlight and extreme temperatures. Avoid storing it near heat sources or in areas where it might be exposed to chemicals or fumes, which can degrade the helmet materials.
5. Troubleshooting
5.1 Helmet Feels Loose or Unstable
- Check Adjustment Dial: Ensure the rear adjustment dial is tightened sufficiently.
- Strap Adjustment: Verify that the side straps form a 'V' shape below your ears and the chin strap is snug.
- Proper Sizing: Confirm you are using the correct helmet size for your head circumference.
5.2 Discomfort or Pressure Points
- Loosen Adjustment: Slightly loosen the rear dial to relieve pressure.
- Pad Placement: Ensure inner pads are correctly seated and not bunched up.
- Chin Pad: Adjust the chin pad position for comfort.
