Page 5: Unpacking Ways Of Main Parts
2 Unpacking Ways Of Main Parts Ordinary Information 1.Please unplug the power cord when you disassemble or maintain the product； 2.Please use the regulation connector lug between the wires as much as possible. Then crimp them firmly by the proper tools and bundle them by the insulating tape; 3.When you plug the wires, please insert the plug to the bottom so it is not easily to be unplugged; 4.Make sure that the wires cannot touch the mobile part such like the drum, and also cannot touch the sharp/hard‐edged party and high‐heat part (motor); 5.Please preserve the screws when you take them down. You will use them when you install the dryer; 6 6.ometimes you must operate the dryer when it is electriferous. In this case, you must be careful and pay attention to the electric shock. - Page 6 2 Unpacking Ways Of Main Parts Steps of disassembling machine Pictures 1.
