To Load Sleeves of Corners Into the Upper Chute

Begin with the upper chute lowered, so you can easily reach the chute.  
Locate the markings on the sleeve which state UPPER DUAL HEAD (figure 19).  Tear off 

the perforated end of the sleeve, as seen in figure 20.  The arrow head will point to the end 

which needs to be torn off, to ensure that the corners are loaded right side up.
Using your index finger on your right hand, hold the corners in place, and invert the sleeve.  

Your finger should keep the corners from falling out.  See figure 21.
Load the opened sleeve into position, enduring that the box sits inside the guide shown in 

figure 22.  
Use the bungee to secure the sleeve to the chute (figure 23).
