Operation Modes
The fuze has two operation modes, which are selectable, by built-in setter and wrench:

position “O”	for SQ action
position “З”	for delayed action

 
Fuze Safety
Before firing the Safety and Arm device prevents the ignition primer from positioning into the fire train. Even in case of unintentional ignition of the primer, no transfer of the firing pulse to the fire train can occur.
 
Fuze arming
The fuze is armed within 5 to 20 m from muzzle. At firing the set-back forces arm the fuze, fixing the elements of the fire train in one line.
 
Fuze ACTION
Upon impact  the fuze provides SQ or delayed action of 0.006 to 0.015 s.
The fuze functions under the impact and inertia forces. The inertia device ensures ignition not only upon impact on solid ground, but also on snow or marshy ground
