SAFETY

Miss-sequencing: Prevents arming the fuze whenever arming condition of “air flow” precedes arming condition of “set back”. Arming distance: 70m minimum from muzzle. Double loading: The fuze will not function in bore in at double loading event. Shorted electric detonator: The electric detonator is shortened until arming. Safety pull wire: No use of safety pull wire.
