First, dig a 40*40*40cm hole in the ground. Note the individual metal teeth and the position of the turntable. Now rotate the bottom plate and tighten the screws on the umbrella stand tube and the bottom plate. 2. Make sure the two parts are mated and there is no cement in the threaded hole. Fill the gap with cement so that the base is embedded in the cement. 3. Use a spirit level to check the alignment of the stand. It takes about three days for the cement to harden. After that, you can finish installing and using your umbrella.
