                 Sheer Pin:
              
            
            
              The yoke on thePTOdrive shaft is designed
            
            
              with a shear pin to prevent damage to drive
            
            
              components should themachine encounter
            
            
              a shock or high load condition.  Replace
            
            
              the shear bolt with a 5/16" Grade 5 bolt or
            
            
              equivalent if it has sheared.
            
            
              
                Do not use a
              
            
            
              
                higher grade or strength bolt.
              
            
            
              To reduce the chance of breaking the shear
            
            
              pin:
            
            
              a. Slow the roller and wheel speed to
            
            
              reduce the load on the drive compo-
            
            
              nents.
            
            
              b. Remove all obstructions from the bag
            
            
              or grain when flling the bag or before
            
            
              emptying.
            
            
              c. Fill the bag with dry grain to prevent
            
            
              the material from freezing into a solid
            
            
              lump.

                 Overloading:
              
            
            
              The machine is designed with a spring-
            
            
              loaded access door that will open to allow
            
            
              material being forced into the lift auger to
            
            
              escape.  Slow the speed of travel into the
            
            
              bag to reduce the amount of grain being
            
            
              pushed into the lift auger assembly.  This
            
            
              will allow the lift auger to remove the grain
            
            
              as it moves into the lift auger assembly.

                 Clean Out:
              
            
            
              The machine is designed with 2 access
            
            
              panels on the bottom of the pick-up as-
            
            
              sembly to allow the unit to be completely
            
            
              cleaned out.  Be sure to tighten panel
            
            
              fasteners to their specifed torque when
            
            
              re-installing the panels.
