WARNING
COUPLING/UNCOUPLING
During coupling to prime mover, it may be required to adjust the angle of the main frame (WP 0005) to
accommodate the height of the fifth wheel plate. Always ensure when coupling that the transport legs and
bottom pressure relief valve assembly do not make contact with the prime mover.
Failure to comply may
result in injury or death to personnel.
All persons not involved in coupling/uncoupling operation must stand clear of prime mover and fifth wheel
towing device to prevent serious injury or death.
Never stand between the prime mover and fifth wheel towing device when the prime mover is being backed
up to the fifth wheel towing device.
Serious injury or death may result.
WARNING
LOADING/UNLOADING OPERATION
All persons not involved in the loading or unloading operation must stand clear of prime mover and fifth wheel
towing device.
Failure to comply may result in injury or death to personnel.
Due to the dimensions and center of gravity of some loads, proper procedures must be followed when
loading and unloading equipment to prevent damage to equipment and injury or death to personnel.
Visibility from the prime mover is significantly reduced when backing, whether the fifth wheel towing device is
loaded or not. Proper procedures must be followed and extreme caution used when backing to prevent
damage to equipment and injury or death to personnel.
Use extremely low speed when loading and unloading vehicles. Higher speeds will exaggerate motions and
create hazardous conditions, which could result in personnel injury or death or damage to equipment.
Tow bar assemblies weigh 47 lbs. Use an assistant and caution when removing and handling them to prevent
injury or death to personnel and damage to equipment.
The location of the boom extension clevis tiedown chains should be located between the rear of the cab and
the forward rear axle on towed vehicle frame.
Failure to comply may result in injury or death to personnel.
