PULL FRICTION
FUZE, M2

 
 
 
 
 
 

GENERAL:

This device is designed for firing explosive charges by means of a trip wire. A direct pull of 3 to 9 pounds will actuate the device.

DESCRIPTION:

The principal parts of the device are the black bakelite body, pull ring and spring, coated wire, friction compund, safety pin, and non-removable base. The fuze is assem-bled when issued with the safety pin inserted through the body to prevent premature ignition.

USES:

To activate anti-tank mines or anti-personnel mines, to supplement warning measu-res and to impede advance of enemy troops by running out trip wires connected to anti-personnel mines along a route of probable enemy movement, to set off booby traps, to set off explosive charges instantaneously when electric means are not avail-able, to prevent removal by enemy of prepared demolition charges or delayed-action mines.

OPERATION:

When fuze is set with blasting cap crimped to the base and inserted in an explosive charge, the safety pin is removed. A pull of 3 to 9 pounds on the pull ring will stretch the spring and draw the coated wire through the friction compound. The friction com-pound ignites and shoots a flame out of the open end of the base to detonate the blasting cap and the main charge.

REMARKS:

(1) An unfired device may be re-used provided it has been in a dry place.

(2) DO NOT ATTEMPT TO REMOVE BASE FROM FURE BODY.
