52. General

The Germans employed only one pull, tension-release fuze, the Z.u.Z.Z. 35 (par. 53). This fuze proved to be dangerous to handle and was modified by cutting off the hole for the taut trip wire at the end of the pull cylinder. This modified Z.u. Z.Z. 35 (par. 45) was marked NUR ZUGZÜNDER (only pull fuze) on the case. It operated by the withdrawal of the safety pin which had a trip wire attached.

53. Pull Tension-Release Fuze 35 (Zug- und Zerschneidezünder 35; Z.u.Z.Z. 35)

a. Description. The pull, tension-release fuze 35 (fig. 54) is an instantaneous, mechanical type. Externally, it closely resemble the pull fuze 35 (par. 44), except that the case is longer and the safety-pin projects through the pull cylinder flush with the top of the cy-lindrical brass case. The fuze is 4 3/8 inches long. The cy-lindrical brass case contains a spring-loaded striker held inside a spring-loaded pull cylinder by two striker-retaining pins. A brass collar at the top of the fuze encloses the pull cylinder and has two slots through which the safety pin is inserted. At the end of the pull cylinder, which projects above the top of the fuze, is a trip-wire hole. Just below the trip-wire hole is a safety-pin hole. The slots in the brass collar permit positioning of the pull cylinder for easy removal of the safety pin when the fuze is to be armed.

b. Employment. This fuze is used with anti-personnel mines, inprovised mines, booby traps, and activated antitanks mines.

c. Functioning. When properly armed, this fuze functions when the taut trip wire is pulled or cut.

(1)

When the wire is cut, the pull cylinder, under pressure of the main spring, moves downward until the striker-retaining pins escape into the lower recess, releasing the spring-loaded striker against the percussion cap.

(2)

A pull of at least 9 pounds on the trip wire pulls out the pull cylinder, further com-pressing the main spring until the striker-retaining pins escape into the upper re-cess, releasing the spring-loaded striker against the percussion cap.

d. Installing and Arming.

(1)

Insert a detoantor into the fuze.

(2)

Screw the fuze into the mine or charge.

(3)

Anchor the taut trip wire.

(4)

Tie the loose end of the taut trip wire to the trip-wire hole in the end of the pull cylinder, adjusting the tension of the trip wire so the safety pin is positioned nearly in the center of the slots in the brass collar. If the safety pin bears against either end of the safety-pin slot, the pin cannot be readily withdrawn.

(5)

Unscrew the retaining nut on the safety pin and withdrawn the safety pin with a long piece of wire or cord.

Note. The Germans provided this fuze with an 8-inch tube of heavy cloth to cover the fuze and part of the trip wire. This allows the pull cylinder to move freely when the fuze is buried in the ground or among camouflaged materials.

e. Neutralizing.

(1)

Insert a pin or nail into the safety-pin hole through the safety-pin slot. Tape it in position.

(2)

Cut the taut trip wire after checking the anchor end.

(3)

Unscrew the fuze and remove the detonator.
