Preparation: The cap is removed, a detonator is inserted in the recess, the grooves in the detonator being placed opposite the pins on the body, and the detonator is then pressed home and turned to the left (its flange being under the heads of the two pins) until the spring on the detonator flange is released thus locking it in position.
The cap is then replaced and turned into the position “Travel.”
The safety pin must on no account be withdrawn during these operations.
The cap from one grenade will not invariably fit another grenade well, and steps should be taken to prevent caps and grenades being interchanged.
Throwing the Grenade: When it is required to use the grenades, all on the belt should be turned to “Fire,” and the whipcord beckets and leather strips should be removed from the safety pins.
When a grenade is taken from the belt, the streamer is unwound and allowed to hang free, and the safety pin is withdrawn immediately before throwing.
The grenade is grasped by the end of the handle and thrown in the required direction, care being taken that the streamer does not get entangled with the thrower.
To insure the grenade firing on impact, it should be thrown well upwards, at an angle of not less than 35 degrees.
Should the grenade not be used the cap should be turned back to “Travel” and the safety pin replaced and secured by passing the whipcord becket over the cap and threading the leather strip through the slot in the end of the safety pin.
