WARNING SUMMARY (Cont’d) • Avoid using fire extinguisher in unventilated areas. Prolonged inhalation exposure to extinguishing agent or fumes from burning material may cause injury to personnel. Using fire extinguisher in windy area will cause rapid dispersal of extinguishing agent and reduce effectiveness in fire control. • Vehicle operation in snow is a hazardous condition. Operator must travel at reduced speeds and be prepared to meet sudden changes in road conditions. Pump brakes gradually when stopping vehicle on ice or snow. Sudden braking will cause wheels to lock and vehicle to slide out of control causing damage to vehicle and injury or death to personnel. • Do not rely on wet service brakes. Keep applying brakes until they dry out and uneven braking ceases. Failure to do this may cause damage to vehicle and injury or death to personnel. • Exhaust components are hot after prolonged vehicle use. Ensure exhaust system components are cool before removing/installing exhaust assembly. Failure to do this will result in injury to personnel. • Do not use the hand throttle as an automatic speed or cruise control. The hand throttle does not automatically disengage when brake is applied, resulting in increased stopping distances and possible hazardous and unsafe operation. Injury to personnel or damage to equipment may result. • Do not operate heater when ventilation system is on. Damage to heater or injury to personnel will result. • To ensure opening of the hood assembly is accomplished safely and effectively, always maintain the proper lifting posture, legs bent with back straight. When raising and securing hood, make sure the hood prop rod is secured to hood support bracket. When releasing hood prop rod, do not pull rod at hook end. Damage to equipment or injury to personnel will occur if hood is not raised, secured, and lowered properly. • If NBC exposure is suspected, all air filter media should be handled by personnel wearing protective equipment. Consult your unit NBC officer or NBC NCO for appropriate handling or disposal instructions. • Radial and bias ply tires should not be mixed on the same vehicle. Injury to personnel or damage to equipment may result. • Do not use bias ply tires on the M1097, M1123, or any A1 and A2 models, under any condition. Due to tire load ratings and vehicle load carrying capabilities, only the load range “D” radial tire can be used on the M1097, M1123, and all A1 and A2 models. • For M1097, M1123, and all A1 and A2 model vehicles only, hearing protection is required for driver and passengers when engine is running. Noise levels produced by these vehicles exceed 85 dBA, which may cause injury to personnel. • The Department of Transportation requires 105 mm cannon ammunition to be in wooden boxes when transporting ammunition on public highways. Movement of cannon ammunition in fiber containers (inner pack) in the vehicle ammunition rack is restricted to other than public highways. • Do not operate the vehicle without the windshield assembly positioned upright and the “B” pillar securely attached. Operation of the vehicle without these structures in place may result in injury to personnel and damage to equipment. TM 9-2320-280-10 Change 1 warning c
