A meter and a screw driver are all you need for tools usually. They used to make special tools for bending the tab but you can do that with a needle nose pliers. It takes just a touch, very little movement to get where you want to go. At least one of the threads mentions to set the cover carefully in place and check the adjustments, the steel cover does affect the magnetic adjustments.
