31–00 Safety Precautions
Safety Precautions in this section apply to all
procedures within this group.
DANGER
When working on the vehicle, shut down the en-
gine, set the parking brake, and chock the tires.
Before working under the vehicle, always place
jack stands under the frame rails to ensure the
vehicle can not drop. Failure to follow these steps
could result in serious personal injury or death.
31–01 Fifth Wheel Inspection
WARNING
All fifth wheel maintenance, adjustment, and re-
building must be done only by a qualified me-
chanic. Improper or incomplete procedures could
result in a possible disengagement of the trailer
from the tractor, which could result in personal
injury or property damage.
Parts are under spring compression. Wear safety
goggles while servicing the fifth wheel. Failure to
do so can result in personal injury, due to parts
ejecting with force.
