— Measure the stack to check the width.

DO NOT use the dado stack if the arbor nut and arbor flange will not fully thread onto the arbor. The arbor nut may come loose, allowing the dado blades to fly out of the table saw, causing serious injury or death.

6. Set the dado blades to the desired height,

make a test run in scrap wood, and then measure the finished dado to make sure it is the correct depth and width.

7. If the width is incorrect, repeat Steps 2–6, adding or removing shims between the chip per blades to reach the desired width.

Never reach behind the dado or place hands in the path of the dado while the saw is run

ning. If kickback occurs while reaching over

the blade, hands or arms will be pulled into the spinning saw blade causing serious injury.
