46. Pull Fuze Z.Z. (Zugzünder)

a. Description. The pull fuze Z.Z. (fig. 46) is an instantaneous, mechanical fuze contain-ing a spring-loaded striker with a lapped joint release. It is housed in a cylindrical brass case. The spring-loaded striker is recessed at the top and held to the pull cap by a lap-ped joint. A threaded percussion-cap assembly is screwed into the base of the fuze. The fuze measures 3 7/16 inches in lenght and 1/2 inch in diameter.

b. Employment. This fuze is used to activate antitank mines, booby traps, and antiper-sonnel mines.

c. Functioning. An outward pull of approxinately 3 pounds on the pull ring compress the striker spring, pulls the striker shaft partially out of the top of the fuze, and shears the lapped joint between the pull cap and the striker shaft. This action releases the spring-loaded striker against the percussion cap.

d. Installing and Arming.

(1)

Insert a detonator into the fuze.

(2)

Insert the fuze and detonator into a mine or charge.

(3)

Attach one end of a slack trip wire to the pull ring of the fuze and attach the other end of the trip wire to the anchor.

e. Neutralizing. Since this fuze is not provided with a safety device, the mine or charge should be destroyed in place.

Caution: Care must be taken when tying a trip wire to the pull ring not exert any pull on the ring since the fuze will function when approximately 3 pounds of pull are exerted on the pull ring.
