Towing vehicle manual.
The trailer must be prepared before and after each trailering operation. The paragraphs in this work
package provide the data and procedures to be used by the Operator when operating the trailer. Items
covered include loading trailer, operating trailer lights, operating trailer service brakes, towing trailer,
parking trailer, chocking trailer wheels, draining air tank, and unloading trailer.

comply may result in serious injury or death to personnel or damage to
Heavy objects/loads, such as tool boxes and heavy parts, must always be
positioned as low as possible in the trailer with the weight distributed as
