Using your Zimmerman outdoor square market umbrella is a breeze. First, assemble it following the included instructions. Once assembled, use the crank mechanism to easily open and close the umbrella. You can also adjust the tilt to block the sun from different angles. When it comes to maintenance, it's important to take good care of your umbrella. When not in use, either store it indoors or cover it well to protect it from the elements. 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 you spill something on it, quickly clean it up with a slightly damp sponge before the spill hardens or leaves a stain. And remember, never use bleach solutions as they can damage the umbrella.
