Using this Tony Kart OTK water pump is easy. First, make sure it's properly connected to the water source and the place where you want the water to go. You can use standard hoses for the connection. Turn it on, and it will start pumping water right away. When using, keep an eye on the water flow. If it seems too slow or stops, check for any blockages in the hoses or the pump itself. For maintenance, it's a good idea to clean the pump regularly. You can use a soft brush to remove any dirt or debris. Also, store it in a dry place when not in use to prevent rust and damage. Avoid using it with dirty or abrasive water for long periods as it may wear out the pump parts.
