Using the Bosch TS1012 zero clearance insert is easy. First, make sure your Bosch GTS1031 table saw is turned off. Then, use the included hardware to attach the insert to the saw. You're now ready to make precise 90 - degree cuts. When using it, always wear safety goggles. Don't force the material through the saw. For maintenance, keep the insert clean. Wipe it down after each use to prevent debris buildup. If it gets dirty, you can wash it with mild soap and water. Just let it dry completely before using it again.
