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. Damage to equipment and injury to
personnel may occur if these instructions are not followed.
• The automatic transmissions on M1123 and “A2” vehicles have a “PARK”
position. Never use the transmission shift lever in place of the parking brake.
Set the parking brake. Ensure the transmission shift lever in in the “P” (park)
position and transfer case shift lever is NOT in the “N” (neutral) position.
Damage to equipment and injury to personnel may occur if these instructions
are not followed.
• Ensure all slack from two-point seatbelt adjusting strap or three-point seatbelt
is removed. Two-point seatbelt retracts but does not lock in any position. Three-
point seatbelt retracts and will lock only during sudden stops or impact. Injury
to personnel will result if an accident occurs and seatbelts are not in use or
adjusted properly.
• Extreme caution shall be taken when transporting personnel. Rollover
protection and seatbelts are available for the crew area only and are not
provided in the troop/cargo area. Despite certain design characteristics of the
vehicle, such as improved capabilities, failure to use basic safe driving skills may
result in injury or death to personnel and damage to equipment.
• Operators are reminded to observe basic safe driving techniques/skills when
operating vehicle. Vehicle speed must be reduced consistent with weather and
road/terrain conditions. Obstacles such as stumps and boulders must be avoided.

Armaments Command, ATTN: AMSTA-CM-S, Warren, MI 48397-5000.
• Prior to towing vehicle with rear wheels up, secure steering wheel to prevent
front wheels from turning.
