Persons who are not charged with work with
auxiliary device of a tractor must not stand between
a tractor and connected machinery (tools) - (A).
Do not park tractor with mounted tools in a lifted
position (B). When driving without tools it is neces-
sary to connect lower draw bars (5) by springs and
upper draw bars (1) to be placed to a flexible linkage!
When transporting tools it is necessary to adjust
limiting draw bars (4) of lower draw bars so that there
would be no unwanted side movement of tools!
