With the blade gear removed, it is time to focus on the power base. Use a small screwdriver or similar to remove the four rubber feet from the base. No glue is used, they are simply pressed in the openings

Underneath each one of the rubber feet is a screw that can be removed with either a Phillips or flat head screw driver.

Here are the four screws and the rubber feet once they are removed. The screws are 1/8X1/2 self tapping.
