The palm router is one of the most versatile electrical tools out there, you can even plunge with it. To plunge with a palm router, you will need to use guides and jigs that you will need to buy separately as an add-on accessory. You will need to clamp the guide into the right position so that when the router is plunged, it will line up with the dado joint you are cutting. The router should be installed in the collet before being adjusted to the depth that you want it to go. Next, place the router against the guide and pull the trigger while pushing downward with both hands. The router should be moved from left to right in the same direction as the cut. When you have finished the cut, release both of the handles which will allow the router to retract back into the base. If you want to cut profile edges, you can do the same thing but first, you must install a router that is compatible such as a round over that will have a component that will guide you along the edge of the piece. Then, like last time set the depth you want before firmly pressing down with both hands holding the handles. Make sure to push against the edge so that the bit is engaged and move the router left to right.
