The only thing not so intuitive is a manual shy Leien like me is that one does not put the staples or nails as in a normal stapler from behind on the clamping slide but the unit upside down must hold and direct the brackets sets purely at the outlet. Then the clamping slide before pushing again and turn the power on again.
Did not much stapled but uptight has until now nothing and even the nails are 1A just stapled to the wood.
