b. Description.

(1) The mine body is a rectangular container (approximately 7 by 4½ by 2½ inches) filled with a high-explosive charge of tetrytol. The fuze well is located in the center of the top surface and at one end is an activator well that will accommodate any standard firing mechanism. The pressure plate is shaped to the contour of the mine body and is slotted so that it may be guided by rivets in the sides of the mine body, into position over the fuze. A small circular pad on the under side of the pressure plate bears against the head of the fuze.

(2) The fuze is issued with this mine is FUZE, chemical mine antitank, T9. A brass pis-ton protrudes from the fuze body through a circular opening in a steel spring. A safety key straddles the compression sleeve which is located between the fuze body and piston head. A force of approximately 300 to 400 pounds on the pressure plate is required to activate the fuze.

c. Fuzing.

(1) Lift pressure plate and insert fuze, first being sure the well is free of any foreign matter.

(2) Remove safety key.

(3) Slide pressure plate into position over the fuze. Center the plate so the rivets in the sides of the mine are located in the vertical slots of the pressure plate.

(4) Plant mine. Pressure plate side may be up or down.

d. Defuzing. This mine may be defuzed by reversing the steps in c above.

e. Antiremoval Devices.

(1) Any standard firing mechanism with a Corps of Engineers blasting cap crimped to it, may be inserted in the activator well. For methods of installation, refer to paragraphs 24 to 26, inclusive.

(2) The mine may be disarmed as follows:

(a) Replace all safety devices.

(b) Cut pull or trip wires.

(c) Unscrew the firing mechanism from the activator well.

(d) Unscrew the base from the firing mechanism. Store these two items separately.

CAUTION: DO NOT ATTEMPT TO REMOVE THE BLASTING CAP FROM THE BASE.
