Hello, this is Matthew Christian from Tampa, Florida and on behalf of Expert Village, today we're here to talk about cordless nail guns. In the rear event that you're using your nail gun, and you get a jam and this can be caused by a number of things that's possible that you were nailing into a wall and hit something hard like perhaps concrete and it caused the nail to jam inside the head of the nail gun. Well to clear this jam, first we will depress this lock nut and remove our nails. Then we will lift up this locking mechanism on top of the nail head and open it up like so and now we can clear the jammed nail. It's not recommended to use any screwdrivers or anything that may mar the surface that the nail travels in. If you need to use something to free that nail, do so with care and try not to mar the surface in here where the nail travels. You may cause damage to the unit. Once you have the nail cleared, close the lid, make sure this little tab is in place, close it, reinsert your nails, pull back the latch, and you're ready to go again.
