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.
