Seems you don't see that warning as much these days. I guess someone has figured out that no "User" is going to try to fix anything, anymore, anyway.
Except me, and, I'm sure, some of you all.
I bought this Wagner Furno 500 heat gun a little over a year ago.

As the old, black one I'd been using for twenty-odd years decided to turn into a Roman candle.
I went to use it today and the only button that worked was the on/off. No heat control (it starts on 2 of 5 bars) and no fan control (two-speed). The buttons felt like physical buttons, a haptic click, but weren't moving anymore.
I figured that I could fix that. Disassembly was pretty straightforward. The black plastic cover on the front pried off easily, revealing two screws. Two more in the handle and it still won't come apart, because, of course, there's always the one hidden under the label.


The surface mount micro-switches on the PC board worked just fine. The red plastic "buttons" were jammed in the black escutcheon, which was warped--a heat gun that isn't heat-resistant. Good planning.
Anyway, I got out some files and opened up the clearances by filing the buttons and the escutcheon.

It was easier to hold the file on the desk and scrub the buttons against it.
Back together and no extra parts! This is the display when turned on:

I can now use the buttons to access the heat and fan controls!

The escutcheon is still some warped and I have to smack it with my hand occasionally, but fifteen minutes to save a $35 (locally) tool that I need today... well worth it! Now to figure out how to replace the utterly worthless, stiff-as-rebar cord it came with....
Let's see some things you all weren't supposed to fix but did!
