Using this umbrella is easy. First, find a flat and stable spot on your patio or deck. Then, place the umbrella firmly on the base. Open it up by pulling the lever or turning the crank. When not in use, close it properly to protect it from the elements. As for maintenance, clean it regularly with a mild soap and water solution. Make sure to dry it completely before storing it. Avoid using harsh chemicals or abrasive materials as they may damage the polyester fabric or the aluminum frame. Also, in case of strong winds, it's best to take the umbrella down to prevent it from getting damaged.
