SUOMY City Tour - Manual (Page 21)

QUICK RELEASE see figure 3
Adjust the length of the strap making the tongue slide into the buckle (A) so that, when the helmet is fastened, the strap presses close against
the jaw and there are the following conditions:
- The helmet can no longer be taken off
- By pulling the helmet from the back and rotating it towards the front, the helmet cannot be removed and it remains well fixed on your head
If the helmet tends to slide off or rotates freely on the head, adjust the strap again until the right pressure is obtained and repeat the test.
If after repeating the test you are not able to efficiently tighten the retention system, do not use the helmet.
After adjusting the length of the strap make sure the end part of the strap is correctly positioned in the adjustment buckle.
Use the unlocking tongue only to remove the helmet! Never unlock while riding.
Closing the strap: push the metal tongue (C) inside the buckle (see figure 3) until the retention system clicks. When it is closed pull tightly on
the strap to make sure it has been locked correctly.
Unlocking the strap: push the red button (B) in the direction indicated in the figure (D) until the tongue is completely released.
LATERAL AIR INTAKES – FUNCTIONING see figure 4
Le prese aria fisse superiori consentono attraverso lo sfruttamento dell’effetto venturi l’estrazione dell’aria dall’interno del casco.
La forma delle stesse e’ stata studiata al fine di ottimizzare tale effetto e garantire cosi’ una notevole estrazione di aria mantenendo una perfetta
efficienza aerodinamica. La particolare forma e’ inoltre in grado di ridurre al minimo le turbolenze e limitare i possibili scuotimenti del casco stesso.
REAR AIR INTAKE – FUNCTIONING see fig. 4
The innovative rear air-intake on the CITY TOUR is designed to improve the
inner ventilation using the remaining airflow, which, thanks to Venturi effect,
can create a depression under the air-intake. In this way a considerable warm
air extraction is allowed and therefore the maintenance of a comfortable
temperature even in the back side (back of the neck).
