Easy pro disk repair machine (JFJ). This machine comes with a thermal sensor that shuts off the machine automatically when it gets to hot. This will protect the motor and extend the life of the machine. After your machine has shut down, you'll need to allow it to cool for 15-20 minutes. The yellow push buttons only require you to press the button and hold it for two seconds. The timer is set to a 3-second delay, and by pressing the buttons continuously the machine will not start. Easy Pro #1 (blue), Easy Pro #2 (white), and 2 East Pro Buffering Pads.
