Hello, this is Matthew Christian from Tampa, Florida and on behalf of Expert Village, today we're here to talk about cordless nail guns. This model cordless nailer comes with an adjustment. What that adjustment is is the depth or flush setting of your nail. There may be in some cases where you're nailing to a very hard wood and the nailer is not driving the nail deep enough where the nail may be sticking out of the surface of the wood. Or there may be some instances where the nailer is driving the nail too deep. Well there's a setting for this and it's right here, it has little arrows to show you. You can turn the adjustment that way to get more of a flushed nail meaning flush the nail is close to the surface of the board. Or you could go deeper by adjusting the dial in this direction and that will drive the nail deeper into with the width that you're attempting to fix.
