The fuze FZ 104 has the following safety arrangements
a) The striker is held in its position by a supporting cross pin and inner sleeve till it gets an impact.
b) The sleeves provide safety against functioning by rain drops
c) The stirrup spring of firing pin locks the rotor in the unarmed position during the storage and transport.
After firing, the delayed arming pellet prevents the firing from being pushed up by its springs to release the rotor, until it is consumed. This ensures a delay in arming at least 60 m from the muzzle of the gun.
