Section XII

Preparation of 2.36-inch AT rocket launcher M1A1 prior to shipment  ....
Storage  .................................................................................................


a. Lubrication. Lubrication of the 2.36-inch AT Rocket Launcher M1A1 shall be performed as directed in paragraph 16.

b. Painting.

(1) REMOVING RUST SPOTS. All painted surfaces that have become checked, pitted, or rusted, shall be thoroughly cleaned with CLOTH, crocus, removing all rust spots. (All external metal surfaces must have a coating of paint, except the contact springs and the flash deflectors. These parts must be completely waterproofed.)

(2) APPLICATION OF PRIMER, SYNTHETIC, RUST-INHIBITING. Apply a liberal coating of PRIMER, synthetic, rust-inhibiting over entire area of the cleaned surface to be repainted as follows:

(a) Brushing or Spraying. PRIMER, synthetic, rust-inhibiting, should be used on bare metal as a base coat for synthetic enamel. It may be applied either by brushing or spraying. The primer will brush satisfactorily as received or after the addition of not more than 5 percent by volume of the proper thinner. For spraying, the primer may be thinned with not more than 15 percent by volume of thinner. Allow to dry thoroughly.

(3) SANDPAPERING SURFACES. Sandpaper the primed surfaces with PAPER, flint, class B, grade No. 00, and wipe all particles of dust from surfaces.

(4) APPLICATION OF ENAMEL. Apply coat of ENAMEL, synthetic, olive-drab, lusterless, and allow to dry thoroughly before the materiel is used.

c. Cleaning. The bore of the 2.36-inch AT Rocket Launcher M1A1 shall be thoroughly cleaned with SOLVENT, dry-cleaning, or with a soap solution as follows:

(1) Apply SOLVENT, dry-cleaning, to clean cloth attached to a ram rod and swab thoroughly. Repeat this operation until all traces of dirt, grease, and foreign matter have been removed. Dry thoroughly using clean cloths.

(2) Apply soap solution by vigorously swabbing the bore until all traces of contamination have been removed. The bore shall then be rinsed with clean, hot water, and dried thoroughly.

(3) Avoid contact of bare hands with the cleaned surface.

d. Preservation of Materiel. Application of preservative shall be performed immediately after cleaning.

(1) Using a rain rod and clean cloths soaked in OIL, lubricating, preservative, medium, swab the bore of the launcher thoroughly using a generous quantity of the preservative.

(2) Repeat operation until all interior surfaces of the bore are thoroughly covered with a protective coating of the preservative.

(3) Apply OIL, lubricating, preservative, medium, to contact springs and flash deflectors.

e. Boxing of Materiel (figs. 19 and 20).

(1) BILL OF MATERIAL. The following is a bill of material required to construct one complete nailed wood shipping box, style 4, for six 2.36-inch AT Rocket Launchers M1A1 including slings and flash deflectors referred to in illustrations, figures 19 and 20.

(2) PACKING PROCEDURE (figs. 19 and 20).

(a) Wrap launchers at both ends with greaseproof-waterproof paper and securely bind with TAPE, adhesive, nonhygroscopic.

(b) Wrap each flash deflector with greaseproof-waterproof paper and telescope six wrapped deflectors together.

(c) Cushioning material, such as paper or felt padding, shall be wrapped around launchers where contact is made with blocking in order to prevent chafing of paint.

(d) Entire inside of box shall be lined with an approved type C waterproof paper as specified in U.S. Army Specification No. 100-14A and the edges shall be coated with asphaltum.

(e) Place two blocks (7) and block (11) in guides (5) and slide to bottom of box with cut-outs facing up.

(f) Place two launchers (in opposite directions) on blocks (7) and (11) with the conduit tube facing up. Make sure that cushioning material is separating blocks from launchers.

(g) Place two blocks (8) over launchers with the notched groove of one side of block directly over the conduit tube. Place block (12) in position.

(h) Place six flash deflectors in position on bottom of box with hold-down strip (6) covering flash deflectors as shown in figure 20.

(i) Repeat above operations until box is packed assembling blocks as indicated in figure 20, making sure that three launchers are all in one direction and the other three are in the opposite direction with the conduit tubing facing up.


a. The launcher should be prepared and packed in the same manner as described in paragraph 40 before being stored.
