WARNING SUMMARY (Cont'd) • Never use wheel assemblies with studs which are damaged, loose, or have damaged threads. Damaged studs can cause improper assembly, which could cause individual fasteners to fail. Any of these situa- tions could cause serious injury or death. • Never use tubes in wheel assemblies. Use of a tube defeats built-in safety features, and could allow the wheel to come apart under pressure, resulting in serious injury or death. • Use only replacement parts specified in TM 9-2320-387-24P. Wheels assembled with components which do not meet specifications could cause the assembly to separate under pressure, resulting in serious injury or death. • Never inflate a wheel assembly without having checked wheel locknut torques that ensure that wheel locknuts are tightened to specifications. An assembly with improperly tightened locknuts could separate under pressure, resulting in serious injury or death. • Always use a tire inflation cage for inflation purposes. Stand on one side of cage during inflation; never directly in front. Keep hands out of the cage during inflation. Inflate assembly to recommended pressure using a clip-on air chuck. Do not exceed 30 psi (207 kPa) cold bias tire inflation pressure or 50 psi (344 kPa) cold radial tire inflation pressure. Failure to follow these instructions may result in serious injury or death. • NBC contaminated filters must be handled and disposed of only by authorized and trained personnel. The unit commander or senior officer in charge of maintenance personnel must ensure that prescribed protective clothing (FM 3-4) is used, and prescribed safety measures and decontamination procedures (FM 3-5) are followed. The local unit SOP is responsible for final disposal of contaminated air filters. Failure to do this may cause severe injury to personnel. • Seatbelts are to be replaced as a set. Failure to do this may cause injury to personnel or damage to equipment. • The Department of Transportation requires 105 mm cannon ammunition to be in wooden boxes when trans- porting ammunition on public highways, by fixed wing aircraft, rail, or ship. Movement of cannon ammuni- tion in fiber containers (inner pack) in the HMMWV ammunition rack is restricted to other than public highways. • Air-conditioning system must be discharged prior to replacing components. Failure to do this may result in injury to personnel or damage to equipment. TM 9-2320-387-24-1 Change 1 c/(d blank)
