Saw Blade Alignment on a Table Saw

Saw blade alignment on a table saw:

If the saw blade and the saw are not correctly aligned to the table and the fence, then there is the possibility that a serious accident may occur such as violent kickbacks. An improperly aligned saw can also cause burning, splintering, or chipping on the workpiece. Always read and follow all instructions and warning contained on the machine, on the tool or the tool packaging and in the operators manual for the machine.

Before carrying out the following instructions, make sure that the starter switch is off and that the power is disconnected from the machine. Follow all company and OSHA procedures for "Equipment Power Lockout."

MOUNTING THE SAWBLADE ON TO THE TABLE;
We advise you to use precise measuring instruments when mounting the saw blade on to the arbor. Adjust the arbor to its maximum height. With the aid of the most precise measuring instrument at hand, verify that the saw blade is parallel to the miter gauge crosscuts with the maximum in quality finish and for setting up the fence for ripping.

POSITIONING THE FENCE FOR RIPPING:
After you have positioned the saw blade so that it's parallel to the miter gauge slots, you may proceed with setting the fence. The fence should be set in accordance with the in sturctions found in the operators manual for your machine. Machine manufacturers have recommended fence settings that if not followed could cause injury or death.

The maximum RPM of a circular saw blade varies based on the diameter of the saw blade (table 1). Never exceed the maximum RPM on the balde. Doing so could result in serious injury or death.

The sawblade's projection (t) with respect to the work piece must be greater than the height of the blade's tooth (fig. 18). Increase or decrease the projection of the saw blade to improve finish quality.

The number of teeth cutting the wood simultaneously must be between 3 or 4 for ripping and ideally 5 to 7 for crosscutting. With less than 3 teeth cutting the sawblade begins to vibrate leading to an uneven cut. If you want to cut work pieces with increased thicknesses (T-fig.21), but wish to maintain the same diameter saw blade, then use a blade with less teeth. If instead you want to cut work pieces with a reduced thickness, but also maintain the same diameter saw blade, then use a blade with more teeth.
