15. As the bin is emptied, there will be grain on the floor and in the corners. Attach the
standing floor sweep (see Figure 4.14) onto the end of the steel flex hose (which
was attached to the straight aluminum tube). Although the longer hose adds friction
to the system, with practice, the user can achieve optimal capacity. Move the
standing floor sweep along the bottom of the bin and into the corners. The standing
floor sweep has a long slot all the way along the bottom of itself to draw in the grain.
Also, the standardly supplied air restrictor (optimizer) can be attached to the intake
end of the standing floor sweep. The air restrictor can be closed to enable air and
grain to enter only the floor sweep’s bottom slot, or the air restrictor can be partially
opened to allow air and some grain to enter the end (in addition to the bottom slot),
or the air restrictor can be removed from the end of the standing floor sweep to
enable larger amounts of grain to be drawn into the end of the standing floor sweep.

16. To assist in final clean-up of the remainder of the grain, remove the standing floor
sweep and attach the clean-up nozzle and transition adaptor to the rubber/
durathane (basketweave) hose (see Figure 4.15).
