Check the items below in the order they are listed:

• Whether the wall socket is energized
• Whether the power cord of the machine is connected in place (some models need to be plugged into two power cords)
• Whether the circuit breaker is flipped up (as shown in the picture) at the rear of the machine (only some machines come with it)
• Whether the machine's emergency stop button is released (Turn it clockwise to release)
• Whether the laser button of the machine is pressed and lighted

If all the above steps have been performed correctly and the laser button remains unlit, go check if the fuse in the machine socket has blown (as shown in the video).

If the fuse is good, use a voltage tester to measure the wire's on/off position.

If the laser button does light up but the machine is still unresponsive (and the exhaust fan does not work), the laser button will need to be replaced.

If the machine is not completely unresponsive, please troubleshoot it as if some components are not working.
