a) Harness:
Don the apparatus like you wear a Jacket. Make sure no harness or hose is twisted. Adjust the shoulder straps for a tight but comfortable fit. Close the buckle of the
waist belt and fasten the strap in a comfortable way (Figure 15).

Open slowly the cylinder valve by turning counterclockwise

. Listen the whistle sound and check the pressure gauge indication to be equal or more than
80% of the rated filling pressure, i.e. 240-300bar (Figure 16).
