How to use the Porter Cable drywall sander?

I am about to sand a basement using the PC sander (with vaccum). I will rent it for maybe a day. If you have used this unit what tips can you give, what mistakes to not make?
If this works out I could rent or buy the sander for future jobs since I do basement finishing.

yes
first plug in the sander and get it warmed up. Let it run the whole time you do the rest of the following.
Take your 4 or 6" knife whichever is your favorite in your hand and go over the edges and large blobs and nails to take off the highest spots as well as you can without going nuts.
Then get a bucket and fill it half way with water your empty drywall bucket will be good for this.
Then get a sponge and a scrap or old hand towel
place the sponge and towel into the bucket to make them wet then squeeze them out so they are not dripping with water but have some water in them.
first use the towel and rub lightly on the drywall edges turning the towel to a clean side as it loads with drywall compound.
you will notice that this not only takes off high areas but will fill in slightly low areas or scratches, its like magic.
then after the area you used the towel on drys there will be a grain on it so use the sponge lightly to smoth the area.
remember not to use too much water you dont want so much that it runs down the wall you just need enough to moisten the area your working.
clean your towel and sponge often and change your water as needed.
this will go much faster then sanding and wont cause the dust or cost you $ for sand paper. this is actualy similar to the process plasters use when they wet the wall down and re troul it to give it a glass finnish. they never use sand paper.
then you can turn off the sander and return it to pay the fee.

Clean the filter a lot. Will plug up quickly. Be careful not to keep in one spot too long...will eat the paper off the drywall quick.
