Well you don't mess around! I too bought an 801 skivver a couple of years ago and it has been challenging to get comfortable with. I would suggest the following to climb up the learning curve faster:
Go to YouTube and watch videos about adjusting and using an 801 skivver
Label all of the adjustments on your skivver so that you know exactly what they do! Indicate feed direction as well. I just used a fine Sharpie.
Make sure that your bell knife is sharp! Make sure that your bell knife is ALWAYS sharp!
Set up your machine with each new type of material that you're skivving, it's NOT a "set it and forget it" machine!
Using cheap ABS or PVC plumbing parts from a home center make your own vacuum system if your machine doesn't have one already. Dead simple, inexpensive aand prevents offcuts from messing up your skivving.
Be patient and expect some frustration as you get it figured out!
