1. Remove rear hatch cover.
2. Remove the safety screw of square nuts.
3. Turning the square nut lowers the moving jaws.
4. Remove the shims from the storage slot and place them into the adjustment bin section of the elbow plate. Inserting the shim reduces the size of the discharge, and removing the shim increases the size of the discharge.
5. Screw the loose square nut back into place, making sure that the ruler plate to the right of the square nut is flush with the top cover plate of the spring to maintain the correct amount of spring compression.
6. Re-insert the safety screws, making sure they go through the threaded rod holes, and re-tighten the storage tank cover.
