Using your Walker Edison Circle Weave Outdoor Patio Umbrella Base is a breeze. First, find a flat and stable spot on your patio or deck. Place the base there. Then, insert the interchangeable sizing insert that matches your umbrella pole size into the base. Next, put your umbrella pole into the insert and use the adjustable tightening knob to secure it firmly. As for maintenance, since it's rust and weather - resistant, you don't have to worry too much. But it's a good idea to clean it with mild soap and water every once in a while to keep it looking its best. When the weather gets really harsh, like in a heavy storm or extreme cold, you can store it indoors to extend its lifespan. Also, always check the sizing inserts and the tightening knob regularly to make sure they're in good condition and your umbrella stays secure.
