A raised body (bed) may fall unexpectedly and without warning resulting in personal injury or death. When it is necessary to work under the truck with the body (bed) raised, install the body (bed) retaining pin through the pin bore in the frame and the retaining bracket on the body.

Note: Earlier machines were shipped with two body retaining pins. Later machines were shipped with one body retaining pin. Earlier machines and later machines require the installation of one body retaining pin to properly secure the body in the raised position.
