WARNING
TIRE AND WHEEL ASSEMBLY
• Floor jack, if used, must be positioned directly under axle to prevent slippage. Floor jack must be used only on
a hard, level surface to prevent shifting of semitrailer. Direct all personnel to stay clear of semitrailer when
supported in the air. Failure to comply may result in injury or death to personnel or damage to equipment.
• Tire and wheel assembly weighs 179 lb (81 kg). Use two personnel to handle tire and wheel assembly. Failure
to comply may result in injury to personnel.
• For service and repair tasks on the semitrailer, the ground boards and tire chocks should be used to ensure safe
coupling and prevent semitrailer movement. Failure to comply may result in injury or death to personnel.
• If nuts cannot be torqued, at first opportunity have Organizational Maintenance torque nuts to proper
specifications. If mission allows, stop and check nuts for tightness. Failure to comply may result in injury to
personnel or damage to equipment.
WARNING
TOWING
• Do not tow the semitrailer with the M52, M52A1, or M52A2 truck tractor. The M52 series inherent design
capabilities are not compatible with the semitrailer, and use would result in a serious compromise to the safety
of personnel and equipment.
• Be sure all personnel stand clear of the towing vehicle and semitrailer during coupling operations. Failure to
comply may result in injury or death to personnel.
• Do not tow the semitrailer with an unsecured cargo container. Accident may occur resulting in injury or death
to personnel.
• When transporting the 8-1/2 ft commercial container, the towing vehicle fifth wheel height must not exceed
50.4 in. (1.28 m) to comply with the 157.48 in. (4 m) overall height limit for USAREUR. The M915 fifth wheel
height meets this requirement. Failure to follow this warning may result in injury to personnel or damage to
equipment.
• When towing the semitrailer with M818, M931 series, or M932 series tractors, the fifth wheel wedges must be
in the locked-in (pushed-in) mode for highway and secondary road use, and in the locked-out (pulled-out)
mode for cross-country operation.
• Extreme caution must be exercised in all turns, curves, and highway cloverleafs when towing a high center of
gravity containerized load as containerized load may fall off of trailer.
• Under no circumstances shall speeds exceed the following:
