a. This manual is published for the information and guidance of the using arms and services.

b. There is included as much technical information required for identification, use, and care of the German 88-mm antiaircraft gun as can be ascertained from printed matter and the materiel on hand. Corrections and additions to this manual will be published as the information becomes available.

c. In all cases where the nature of the repair, modification, or adjustment is beyond the scope or facilities of the unit or beyond the scope of this manual, the responsible ordnance service should be informed so that proper instructions may be issued.


a. The mount is a circular pedestal antiaircraft type suspended from two bogies when in traveling position. The mount is equipped with a data transmission indicator for antiaircraft fire. There are also provisions for installing a direct laying sight for antitank fire and a dial sight for indirect fire. A hand driven fuze setter is fitted to the left side of the top carriage. The traversing and elevating mechanism data transmission indicators and direct laying sight are on the right side.

b. Normally, the bottom carriage is in contact with the ground during firing and is stabilized by outriggers. There are four leveling jacks, one at each extremity of the outriggers for leveling the bottom carriage. The top carriage is leveled by two handwheels located 45 degrees from either side of the center line of the front outrigger on the bottom carriage. The leveling system has a range of 9 degrees. The front of the mount is protected by a flat shield of armor plate.
