  There are several reasons why your Kärcher Floor Machine might not start: * The battery plug might not be inserted. Ensure it is properly connected. * The main switch might be off. Set it to “1”. * The safety switch might not be activated. Sit on the seat, as the machine only operates when someone is seated. * The emergency-stop button might be engaged. Release it. * The system may need a reset. Set the key switch to "0", wait about 10 minutes, and then turn it back to "1". Try to use the unit on level surfaces. * The accelerator might be engaged.
