How to cut vin connect on Arduino Motor Shield

I have a new Arduino Motor Shield. I have to connect to it 2 DC Motors 12V. However I read on Shield's documentation that if motors need more than 9V, I have to cut the "vin connect". I'm not very able in electronic: could someone explain me how to cut it in a practical and easy way? Thanks

Can you post a link to the schematic for that shield ?

This is the link for schematic:

It looks like there is a pair of solder pads that connect Vin to V motor. The schematic says the DEFAULT is CLOSED (connected) so if you want to "cut" Vin, just remove the solder on those pads with solder-wick.

Thanks for your helpful answer.
