It sounds like it's binding, but could that be something like when an electric starter goes bad on a car and fails to make good contact? Could binding blades cause the electric bits to do that...could it hurt them permanently?
I just used the thing one time, and it started making an occasional high-pitched noise near the end, like when an electric hair trimmer binds up.

The scissoring blades are not the only moving parts that can make that awful sound. For the blades, just some motor oil will be fine. Be generous, but not so much that it sprays everywhere. And the oil will be a dust magnet too so be aware and clean it. Your goal will to have the surfaces smooth so they glide over each other without binding. A rusty surface will hold more oil, and more dirt and crap, until it's shined up through use. Then a very light coating of oil will be sufficient to keep it going well, and be a much smaller crud magnet.
As to the other parts that might be making the noise and need attention, the commutator brushes on the motor might need some lube / replacement. Also the motor bearings might need some tlc too. If you've cleaned up the blades, and you know it, and it still screeches and groans while running in the air, I would look to the motor parts.
