Set the chinstrap strength according to the risk analysis carried out for planned use of the helmet:

risk of strangulation if helmet is snagged: chinstrap strength set to less than 25 kg
- Warning: the helmet's chinstrap strength is factory-set to greater than 50 kg.
In addition, the chinstrap strength setting also determines your helmet’s certification:

For work at height, the EN 12492 standard requires a chinstrap strength setting greater than 50 kg
EN 397: 2012 standard
(Helmet for industrial use)
For work on the ground, the EN 397 standard requires a chinstrap strength setting less than 25 kg
