Introduction
Make sure the drill is turned "off" before you begin by putting the forward reverse switch in the middle position. Make sure your hands are dry when handling the drill and charger. Make sure you have a clean workspace.

Now take a 8mm or larger Allen Wrench with your dominant hand, and insert it into the chuck.
-
Spin the chuck clockwise to tighten the allen inside as tight as it will go.
-
Set the gear box selector switch on the top of the drill to 1.

-
With your nondominant hand lay the drill flat on the edge of a table such that chuck hangs off the edge. Hold the head of the drill tightly pushing it against the table (not the part with the battery).
-
With your dominant hand, take a rubber mallet and strike the Allen Wrench hard. You want to hit the Allen wrench so that it will move counterclockwise in reference to someone looking at the face of the chuck.
-
It may take more than one hit but the chuck will spin easily once broken free of the threads of the drill spindle. Use the Allen wrench to spin the chuck counterclockwise until separated from the drill.
-
To reassemble your device, follow these instructions in reverse order.

My chuck is ceased in the closed position and I am unable to open it.
Is there any way to open it ?
My chuck was stuck partially open. Could not back the retaining screw all the way out. I had to cut the chuck off with a grinder.
Horrible directions. “Toward you” doesn’t make sense. Establish a frame of reference (facing the chuck) and state clockwise and counter-clockwise. That does make sense.
My drill has a hex screw holding the chuck on… not a Phillips screw shown in the videos. I cannot get the 7/64 Allen wrench to loosen the “reverse thread” screw. Afraid I will break the Allen wrench.
