What should I do if the ear muff air is leaking?

  • Educate the customer: “Don’t push the air pump button past the helmet plate.”

  • If it is a slow leak, try to determine the issue by removing the cheek pads, pumping up the earmuffs to full (firm to the touch), then pressing one side of the ear muffs.
  • If the commander air pressure release button broke off, consider a warranty helmet replacement.
  • If the commander air pump button is pushed in, troubleshoot the solution or consider a warranty helmet replacement.
