The fuze wrench, M18, assembles the fuze to the cartridge, and the bladed tip on the end sets PD-type fuzes. After the mortar is mounted, the gunner makes a thorough check. (5) Do not leave unused increments unburned in combat operational areas. At the muzzle end is a cone-shaped blast attenuator device (BAD) that is fitted to reduce noise. The fuze arms and functions normally when fired at any angle of elevation between 0800 and 1406 mils at charges 1 through 9. This action breaks an internal sheet pin and internal wire, thereby disabling the proximity function. The mount consists of elevating and traversing mechanisms and a bipod (Figure 4-4). The second page includes a chart with range and deflection (presumably for the same kind of shells), as well as notes which give additional instructions. (5) Four inches of elevation shaft are exposed, and the shaft is not bent. The fuze is not intended to function at charge 0. When firing under the control of an FDC, he reports to the FDC that mask clearance cannot be obtained at a certain elevation. The components of the mortar consist of a canon, sight, mount, and baseplate. The striker has been modified to be able to use German and Italian patterns of 81mm mortar . Safety before firing is provided by a safety wire, which must be removed just before firing.
