Additionally, there is a striped pattern on the flywheel that you can
use under a florescent light to adjust the speed. Use the correct
pattern for your local power specs (50 or 60hz)
Oh, don't adjust the variable resistors that have the red wax on them
holding them in place. (don't ask how/why I learned that) The speed
adjustment screw is located on a smallish board towards the back of the
drive and is a small flathead that requires a jewler's screwdriver to
turn it.
