Final answer:
When setting up a table saw, check that the blade is sharp, undamaged, clean, properly aligned with the miter slot and fence, and set to the correct height for safe and accurate cutting.
Step-by-step explanation:
When setting the table saw up for a job, the saw blade should be checked for several key factors to ensure safety and accuracy.
Firstly, one should ensure the blade is sharp and free from damage such as nicks or bent teeth. A dull or damaged blade can lead to inaccurate cuts and can be dangerous.
Secondly, the blade should be checked to make sure it is clean, as pitch and resin buildup can affect the quality of the cut and the operation of the saw.
Finally, the blade should be properly aligned with the miter slot and fence, and set to the correct height for the operation – typically, the blade should extend above the material by about the height of a tooth to minimize the risk of kickback.
