Part 5
Operating Under Normal Unusual Conditions
General
1. Unusual conditions which will require the operator to follow special procedures are described as follows:
a. Exposure to Sand and Dust
(1) Under conditions where sand and dust can enter the bore or working parts of the weapon, strip, clean and lubricate the weapon more frequently: at least once daily.
(2) Reduce lubrication, especially on sliding surfaces, to a minimum. Wipe down all exposed and noncritical operating surfaces.
This will prevent wind blown sand from becoming embedded in the lubricating oil and forming an abrasive.
(3) Keep the weapon covered whenever possible, especially during sand and dust storms.
(4) As soon as practical, upon leaving the sandy and dusty conditions, the weapon shall be cleaned and then lubricated with a general purpose lubricant.
b. Conditions of Severe Cold
(1) All moving parts must be kept free of moisture. When possible, disassemble and clean the weapon outside heated shelters, to prevent the formation of condensation.
(2) Once the weapon has been brought indoors, it must be brought to room temperature, stripped, cleaned and lightly oiled.
In the absence of non-congealing lubricants leave all surfaces free of oil.
(3) Before firing, at temperatures of below -18 degrees C, completely strip and clean the weapon. Cycle the weapon manually at frequent intervals, to ensure correct function.
(4) If the weapon has been fired, swab the bore immediately with several patches saturated in lubricant and then remove all traces of lubricant with dry patches.
(5) Refer to CFTO C-71-010-005/BV-000, Equipment Protection Instruction, Arcticization of Weapons, for detailed instructions.
c. Exposure to Water
(1) After exposure to water, either accidentally splashed or submerged, water seepage into lubricated parts will occur.
Drain, wipe dry, clean and lubricate all weapons which have been exposed to water, especially salt water, as soon as practical.
