Using this Venice 7.5 Ft square crank umbrella is easy. First, you'll need to assemble it as assembly is required. Once assembled, you can open it up to a width of 90 inches, a depth of 90 inches, and a height of 103.54 inches to enjoy its shade outdoors. When you're done using it, close it down to a more compact size. Here are some important things to keep in mind. This umbrella contains nickel compounds which are associated with cancer, so handle it with care. For maintenance, when the umbrella is not in use, store it indoors or cover it well. If there's any wooden part, make sure to keep it away from standing water. Regularly dust the umbrella with a small brush or a vacuum cleaner. If there are spills, clean them up immediately with a slightly damp sponge. Never use bleach solutions as they may damage the umbrella.
