1. Set the decurler unit assembly in the frame.
  2. Fasten the tongue bracket before you attach the front and rear racks (x2).
    • This will ensure that the assembly is properly aligned so that the front and rear racks fit correctly with the front and rear pinion gears below.
    • When re-attaching the front and rear racks, make sure that the racks are flat and that they fit correctly with the pinion gears below, before re-fastening the screws.
