Thanks for posting this, I also was baffled by the four screws included with the sander, I have never installed them, and feel the pads are already hard enough to take on and off without the screws.
Removing the sanding pad (Fig. 3):
- Push the sanding pad forwards (e.g. by
pressing the rear edge of the sanding pad
against a flat surface),
- keep the sanding pad pressed forwards and
swivel the front edge of the sanding pad away
from the tool,
- release the pressure slightly, remove the
sanding pad from the rear.
The new sanding pad is fitted in the reverse
order.
Make sure that the four lugs (3.1) of the sanding
base catch in the four recesses (3.2) in the
sanding pad. To ensure a better grip of the sanding pad on
the sanding base of the LS 130 EQ you can
fasten the sanding pad in the four holes in the
corners (1.7) using the enclosed screws. These
screws have to be removed before
exchanging sanding pads.

I cannot imagine needing those screws even with use of coarse grits. But if you are using one of the double wide or double long pads, or if you broke the retainers on any of these pads, maybe the screws could be used to keep on sanding? (Although I have an LS 130 and the double wide pad, I am just guessing at when these screws might be needed.) Maybe someone from Festool will read this string and let us know.
Well that figures. Right there in the manual. I actually looked through the manual before I posted this. Since I had read the seperate install/removal instructions , I did not thoroughly read through the same instructions in the manual.
