              not exceed the loading capacity of the
            
            
              system.

                It is recommended that 2 people be
              
            
            
              
                involved when operating the Extractor.
              
            
            
              
                One person at the controls to operate
              
            
            
              
                roller engage lever  and the truck driver
              
            
            
              
                in the tractor cab to monitor the opera-
              
            
            
              
                tion. The truck driver is then available to
              
            
            
              
                shut everything down if required.
              
            
            
              
                NOTE
              
            
            
              It is recommended that the truck
            
            
              driver operate the tractor during the
            
            
              loading/unloading operation.
            
            
              
                IMPORTANT
              
            
            
              Do not set park brake on tractor or leave
            
            
              the transmission in gear. Extractor must
            
            
              be able to move both the machine and
            
            
              the tractor into the bag during operation.
            
            
              Setting the park brake on the tractor will
            
            
              prevent this.
