On rare occasions the H3 inflation valve on your board is not tightened 100% by the factory. If this is the case on the board you received, when you try to inflate it you'll notice air seems to be leaking out the side of the valve fitting. If this is the case, get out the included gray plastic valve wrench and tighten the valve fitting by turning it clockwise. You'll have to have the board mostly deflated so you can grip the internal component of the valve with your hand to hold it still while the outer component gets turned with the gray plastic valve wrench.
Because the skin of the board is pretty thick, it's not so easy to get a good grip on the back side of this valve. It's difficult, but not impossible. This is exactly how the factory installs these valves.
