MM3680
Practice M62 and M69 Hand Grenades. The M62 and the M69 practice hand grenade is inspected to see if the
fuze has been fired, even if the safety pin and pin level are still in place. See Figure 13. If the safety pin and
safety lever are missing and if the striker head assembly is over the primer, the fuze has been activated. Turn the
fuze assembly counterclockwise and remove it. Inspect the fuze to ensure that it has been fired. If fired, the fuze
should look dark and burned and the explosive cap will be missing. When inspecting the M62 hand grenade
(Figure 14), remove the stopper from the bottom of the hand grenade and look through the hole for a charge
assembly. If there is a charge assembly, remove it and place it in a suitable container for disposal according to the
SOP. Once the hand grenades have been certified to be free of explosives, they can be packaged and placed back
in storage for reissue. Practice hand grenades are painted blue with white markings.

Antitank M20 Practice Mines. To inspect the antitank M20 practice mine (Figure 15) for explosives, the
arming plug must be removed. To remove the arming plug, first check the selector on the arming plug to see if it
is in the Safe position. If the selector is not in the Safe position, turn it clockwise to the Safe position, then turn
the arming plug counterclockwise and remove it. After removing the arming plug, check the top primary fuze
well for the fuze. If the fuze is present, remove it by hand, making sure that no downward pressure is applied to
the fuze. After removing the fuze, insert a safety fork below the pressure plate so no pressure will be placed
unnecessarily on the mine while inspecting it. Check the secondary fuze wells for activators. If activators are
present, remove them by turning them counterclockwise. Place the activators in a suitable container for disposal
according to the SOP. Remove the filler hole cap to check the inside of the mine for foreign material such as dirt
and sand. Once the M20 mines have been certified to be free of explosives, they can be packaged and placed
back in storage for reissue. Any explosives found should be placed in a suitable container for disposal according
to the SOP.
