DUAL RATCHET
Place the helmet on your head. Push the Dual Ratchet
adjustors until the headband is firm yet comfortable.
If you need to loosen the headband depress the
levers on the adjustors and pull the sliders apart. All
fit adjusments must be made with the helmet in the
proper position. Failure to do this will result in a poor fit.
A poor fit will allow the helmet to move out of position
or come off in an accident. For proper Dual Ratchet
operation, refer to Figure2. For proper position, please
refer to Figure 8.
