CARE AND PRESERVATION
a. Proper functioning and accuracy of firing depend largely on care and cleaning of the weapon. The weapon should be checked daily for cleanliness, in garrison or camp, on the range, and in the field. See that the bore is free of dust, dirt, mud, snow, or other foreign material.
16. CLEANING AND CARE OF LAUNCHER.
a. Daily and Immediately After Firing. Wet a CLOTH, wiping, with CLEANER, rifle bore, and run it through the barrel several times. Then run a dry wiping cloth through until the inside of the barrel is clean and dry. Saturate a clean dry wiping cloth with OIL, lubricating, preservative, light, and then wring it out. Oil the bore by running this cloth back and forth through the barrel.
b. Weekly. Apply one or two drops of OIL, lubricating, preservative, light, to the tail hinge pin.
c. Prior to Firing. Run a clean dry wiping cloth through the barrel until, by the appearance of the cloth, it is indicated that the film of oil has been removed from the bore.
d. External Parts of the Launcher. When necessary, clean the rusted, pitted, and chipped exposed metal surfaces with CLOTH, crocus, and repaint with ENAMEL, synthetic, olive-drab, lusterless. Do not paint the contact springs or the flash deflector. To clean wooden stock and grip, wipe with a clean wiping cloth lightly oiled with OIL, linseed, raw, type A. Then wipe with a clean dry wiping cloth. Do not use cloths which have been impregnated with raw linseed oil on any other parts of the launcher.
e. If Used in Wet Weather. Disassemble the stock and trigger grips and dry all electric contact points and wires with a dry cloth. Clean and oil the rest of the launcher as described above.
