TM 5-3805-260-24Current RecommendationUse dry nitrogen (N2) gas for all pneumatic tires.Nitrogen will not burn inside the tire.WARNINGCorrect nitrogen inflation (charging) equipmentand training in its use are needed to prevent toomuch pressure in a tire. A tire blowout or rimfailure can result from equipment that is notcorrect or is not correctly used.Also, the use of nitrogen instead of air in the tires,decreases the amount of tire deterioration. This isespecially important for tires that have an expected longservice life (4 or more years). It also decreasesdisassembly problems.The pressure of a fully charged nitrogen cylinder isapproximately 15 000 kPa (2200 psi). This highpressure can cause a tire blowout and or rim failure if thecharging equipment is not used correctly. See TireInflation (Charging) With Nitrogen.Tire Inflation (Charging) With NitrogenWARNINGServicing and changing tires and rims can bedangerous. This work must be done only bytrained personnel with correct tools andprocedures. If correct procedures are not followedwhile servicing tires and rims, the assemblies canburst with explosive force and cause seriousphysical injury or death. Follow carefully thespecific information provided by your tire servicingman or dealer.When tires are changed be sure to clean all rim parts.If necessary, paint the components to prevent corrosion.Sand blasting is recommended for removal of rust.Check all components carefully and replace any cracked,badly worn, damaged, severely rusted or corroded partswith new partsof the same size and type. If there is any doubt, replacewith new parts. Never rework, weld, heat or braze anyrim components.The tires on these machines are inflated (charged)with nitrogen instead of air. The recommendation is thatnitrogen be used for pressure adjustments in a tire. Seeyour tire dealer for the correct tire pressures for jobconditions and for any questions on nitrogen inflation.CORRECT POSITION FOR TIRE INFLATION(Behind the Tread)WARNINGA tire blowout or rim failure can occur during tireinflation. To prevent possible injury get next to(behind) the tread, as shown, when inflating a tire.Set the regulator of the nitrogen inflationequipment at no more than 140 kPa (20 psi) overthe correct tire pressure.CAUTIONUse only the 6V4040 Nitrogen Tire Inflation Groupto inflate tires from a nitrogen gas cylinder. SeeSpecial Instruction, Form Number SMHS7867 fortire inflation instruction.Use the same tire pressures for nitrogen inflationthat are used for air inflation. See the Operator’smanual for the shipping and operating pressures.2-156
