Don't go cold turkey in the cold.Cold weather can cause the M157A2 and M56/M58 smoke generators to go cold turkey on smoking. Ice can form in the fog oil tank and block the fog oil lines unless you fortify for·ti·fy v. for·ti·fied, for·ti·fy·ing, for·ti·fies v.tr. To make strong, as: a. To strengthen and secure (a position) with fortifications. b. To reinforce by adding material. your smoke generator with cold weather PM. Here are the cold facts: M157A2 When it's below freezing, have your fuel supply folks add kerosene kerosene or kerosine, colorless, thin mineral oil whose density is between 0.75 and 0.85 grams per cubic centimeter. A mixture of hydrocarbons, it is commonly obtained in the fractional distillation of petroleum as the portion boiling off or diesel fuel to the fog oil to form a mixture that flows easier. OPERATING PERCENTAGE OF FOG OIL TEMPERATURE TO DIESEL/KEROSENE Above 32[degrees]F 100/0 32 to -10 75/25 -11 to -25 60/40 -26 to -40 50/50 The fuel will also need help in the cold. Add 16 ounces of isopropyl alcohol isopropyl alcohol: see isopropanol. , NSN NSN National Stock Number NSN Nokia Siemens Networks NSN National Storytelling Network NSN NATO Stock Number NSN New Substances Notification (CEPA) NSN National Student Number (NZ) NSN Never Say Never 6810-00-286-5435, to each 5 gallons of untreated gasoline or add 2 ounces of icing inhibitor, NSN 6850-01-377-5075, to each 5 gallons of any other untreated fuel. FUEL PREHEAT CYCLE MOGAS 0 JP-1 1 JP-4 1 JP-5 turbine 3 JP-8-turbine 4 Diesel fuel-arctic 4 DF-1 diesel 4 [ILLUSTRATION OMITTED] M56/M58 Add 2 ounces of icing inhibitor, NSN 6850-01 377-5075, to every 5 gallons of turbine fuel to prevent ice forming in the fuel. JP-8 already contains icing inhibitor and doesn't need treatment. How you mix fog oil and turbine fuel to prevent freezing depends on how the visual pump is calibrated cal·i·brate tr.v. cal·i·brat·ed, cal·i·brat·ing, cal·i·brates 1. To check, adjust, or determine by comparison with a standard (the graduations of a quantitative measuring instrument): . If it's calibrated normally, use a fog oil/turbine fuel mix of 100/0 for 0[degrees]F and above and a mix of 80/20 for -25 to 0. If it's calibrated to maximum, the fog oil/turbine fuel mix should be 100/0 for -25 to 0 and 90/10 for -25 to -10. Below -10, 90/10 will yield better smoking. When it's below 0, you also need to set the ejector ejector (ijekt  r),n by common usage, a device used to remove debris and fluids by negative pressure. Another term is aspirator.
