Screwdriver for baby metal drill press

A few times I’ve fancied using this but the top cover is (at least as far as I could see) closed by a security screw - does anyone know where the driver to unscrew this is? Without being able to change speeds the drill is very limited. Had a hunt around but couldn’t see it. Cheers

I have got a set will bring them in

Before we have a induction probably best to leave it on low speed
