Positioning and Angle Adjustment

What happens here

The user positions the sharpener underneath a Cub Cadet electric lawnmower, raising the deck for access. He places the sharpener directly against the mower blade. He notes that the electric mower's blades spin freely, unlike gas mowers, which may require holding the blade in place. He then uses the factory-angle gauge (a small metal piece with angled cuts) included with the sharpener to ensure the grinding wheel matches the mower blade's factory angle. This gauge is stored on the side of the sharpener.

Goal: Correctly position the sharpener and set the grinding angle.
