30. PREVENTIVE MAINTENANCE (figs. 11, 12, and 13).

a. These instructions may be carried out by the using arms.

b. Tighten all screws and nuts to prevent their becoming loose in service. This should be done periodically when the weapon is in service. Clean all rust and pitted surfaces with CLOTH, crocus, and repaint with ENAMEL, synthetic, olive-drab, lusterless.

31. REPAIRS.

a. The following operations must be performed by a company mechanic or ordnance maintenance personnel.

b. Solder all loose or broken soldered connections.

c. Replace any defective bulbs.

d. Remove dents in the barrel by using the tools shown in figures 17 and 18. These tools should be improvised by the ordnance machinist.

(1) Drive the small dent remover (fig. 17) through the barrel. This will increase the diameter of the dented part of the barrel up to 2.187 inches.

(2) Drive the large dent remover (fig. 18) through the barrel. This will bring the diameter of the dented part of the barrel back to the original 2.369 inches.

(3) To restore the original round contour of the barrel, force the dent remover in place under the dents. Using the dent remover as an anvil, hammer the outside surface of the barrel with a ball-peen hammer.
