Make sure the on/off switch is set to off to prevent any accidental unwanted inputs to the machine

Apply heat to the leftmost pad as shown in the image, near where the back of the palm rests while in use.

Once heated, try to gently pry off the PTFE pad with a spudger or a guitar pick

Heat the adhesive again and try to pry it off in one piece so you can reuse it.

In my case, the PTFE came off without the adhesive, if you manage to get it all off at once, even better.

Now, using your T5 Torx screwdriver, remove the 2 screws as marked in the image.
