Pull Friction Fuze M2

General: This device is designed for firing explosive charges by means of a trip wire. A direct pull of three to nine pounds will actuate it.

Description: The principal parts are the black bakelite body, pull ring and spring, coa-ted wire, friction compound, safety pin, and non-removable base. The fuze is assembled when issued, with the safety pin inserted through the body to prevent premature igni-tion.

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

Remarks: An unfired device may be re-used provided it has been in a dry place.

Do not attempt to remove the base from the fuze body.
