What safety precautions should I follow when using the power cord on the XH2164-001?

Only use the power cord included with the machine, and plug it directly into the electrical outlet without using extension cords or multi-plug adapters. Always turn off the main power first before unplugging, and grasp the plug itself rather than pulling on the cord to remove it. Unplug the machine when not in use for a long period of time, and never touch the plug with wet hands to avoid electric shock. (Page 1)
