What is the proper way to remove my kingston device from the jumpdrive?

Either you're talking about removing your kingston device from your computer:
1. You can either just pull out the drive physically while when it is not in use or you can right click on the "Remove Device Safely" icon on the bottom right of your screen where the time is and click on Remove Safely.

OR

You are talking about removing a SD card from an adapter at which point you would just remove the adapter from the computer (if it isn't removed already) then pull out the card.

Either way, you would be safe just pulling on the device in question in either scenario. It is not particularly necessary to follow any other steps although safer other steps may be.

Hope this helps.
