There is no depth adjustment on this tool - If the staples are going too deep - most likely the piston (#17) has threaded off the driver inside the tool, you have a broken piston bumper (#62) inside, or the teflon foot pad (#56) on the bottom of the tool is the wrong thickness for the flooring you are using.
