WARNING SUMMARY • Never open one end of cargo shell door without first ensuring that the opposite end is securely closed. Not doing so may cause both ends to open at the same time, causing damage to equipment, mission abort, or injury to personnel. • Drycleaning solvent is flammable and will not be used near an open flame. A fire extinguisher will be kept nearby when the solvent is used. Use only in well-ventilated places. Failure to do this may result in injury to personnel and/or damage to equipment. • Protective gloves, clothing, and/or respiratory equipment must be worn whenever caustic, toxic, or flammable cleaning solutions are used. Failure to do this may result in injury to personnel and/or damage to equipment. • Do not perform fuel or battery system checks, inspections, or maintenance while smoking or near sparks. Fuel may ignite and batteries may explode causing damage to vehicle and injury or death to personnel. • The automatic transmissions on M998 and “A1” vehicles do not have a “PARK” position. Whenever the vehicle is parked, or the transmission is in “NEUTRAL,” the parking brake MUST BE APPLIED.
