This street sweeper was designed and constructed in
accordance with the state of the art and recognized safety rules
and regulations. Nevertheless, dangers can arise that can

these dangers by reading and observing the information in this
operating manual. In addition, you will be able to take full
advantage of the performance and functions of the street
sweeper and to avoid unnecessary faults.

r
there is a danger of personal injury and property damage.
