The two line pulley clothesline is designed to hang clothes on the bottom line, sharing the weight with the top line by using line separators. The clothes pins and the line separators are stored in the little girl dress holders - which hang in the queen bedroom closet when not in use.
By trial and error, I've worked out the following steps to hang clothes. Of course, you're welcome to work out your own.
To start, stand by the corner of the house and pull the bottom line towards the house until the tensioner (the funny looking aluminum thing) is in front of you. Put the line separators on the lines as shown. The little white wheels go on the top line. It should now look like the following:
Pull the tensioner to the left a little bit to give yourself some room to hang your first item. (If the separators move, scoot them all back to the right against the pulley.)
Hang your first item on the bottom line directly to the right of the aluminum tensioner.
Move the first black separator up against the just hung first item. (Leave the rest of the separators pushed back towards the pulley.)
Hang your next item just to the right of the separator. It should look something like the following pic: tensioner, 1st item, separator, next item.
Continue hanging new items on the bottom line, moving the bottom line to the left as you go. When the top and bottom lines start to separate too much due to the weight of the clothes, bring another separator out from the pulley (and leave the rest back against the pulley).
When you get to your last item to hang, move a separator out against the next-to-last item, then hang your last item to the right of the separator. Your clothes should end looking like the following pic - which shows the next to last item, a separator, then the last item. Unless you hang a lot of clothes, you'll have some unused separators left up against the pulley.
Now run the bottom line out into the sunshine to dry.
When you take your clothes off the line you should end up with 8 separators by the house pulley. If you don't have 8, walk out the line looking for the missing ones on the ground. (Sometime they blow off in the wind.)
