The Operator's Manual is an integral part of the
machine's documentation. That is why each new
operator of the trailer must receive this Operator's
Manual and be trained.
The Operator's Manual describes the basic safety
rules and operation of Pronar T185 agricultural
trailer. If the information contained in the Operator's
Manual needs clarification then the user should refer
for assistance to the sale point where the machine
