Before use, a locking catch on the handle must be released and a fuse, lasting an average of 4 seconds, was inserted into the top of the can. A good throw could send the grenade 30 to 40 metres. Upon detonation the shells fragment in rectangular, thin fragments, which, along with the casing and detonator fragments, deccelerate rapidly in air. Due to the fragments rapid loss of velocity the kill radius is small, making this grenade an "offensive" type. The fragmentation kill radius was approximately 15 metres with the sleeve and 10 metres without. As with most grenades of this era, there is potential for large fragment projection a great distance further than the throw.
