How to make disk sander pad stick

@woodtechs the large abrasive pad doesn’t seem to stay stuck to the Axminster disk sander. The manual talks about an abrasive disk with a backing that needs peeling off.
Do we have any of these?
Or please could someone show me / add instructions to the tool page how to make the pad stick?

~Also, do we have any rougher sanding belts?~ found them

Thank you

The blue one? The velcro pad is a bit melted for that unfortunately - I’ve found it you use the vacuum on max it helps it stick a lot better

Good to know, but I actually meant the standing white one

We need to order a new hook and loop pad for the big disksander (white axminster) and more belts @mbg do you have the details of this machine?
