Stand for drip tank goes inside drip tray, so it serves as a splash gard and water is retained in drip tray.
You can run a 6" or 4" saw on the machine. A 4" saw blade is thinner and a good idea to use for your more expensive material to minimize saw blade loss.
Align the saw body with the saw so blade does not scrape on sides of acrylic cover. When you turn on the saw and it make a scraping noise, turn off machine and adjust.
