Part of the side shell is looped around a screw post. In this step, you’ll spread the screw post apart enough to slip the shell out.

Insert the flat end of a spudger into the gap between the controller ring and the front shell.

The front shell is the plastic frame part below the front trigger.

Twist the spudger to widen the gap between the front shell and the controller.

Position the spudger so that it can stay in place without you holding the tool.
