Making Adjustments to Your Saw
Next, set the tilt angle to 0º. When setting the tilt angle and blade elevation, be sure to back the handwheels off
slightly after reaching the limit stops. As with all table saws, pulling the handwheels tight against the limit stops
can cause a slight twisting of the trunnion assembly and lead to inaccurate alignment measurements.
Raise the blade elevation to about 3 inches above the table. Position the dial test indicator so that the
measurement arm rests against the right side of the blade and about
1
⁄
4
inch above the center of the arbor
fl ange. Slide the mount forward until the measurement arm is about
1
⁄
2
inch inside the front edge of the blade
(see Fig. 94).
Set the dial indicator to zero. Slide the dial test indicator mount smoothly toward the back of the saw until the
measurement arm is about
1
⁄
2
inch inside the rear edge of the blade. Note the reading of the dial indicator as
the mount moves across the blade.
If the dial indicator moves positive and then negative (or vice versa) a substantial amount, or if there is a
sudden change in the reading rather than a gradual change, this indicates a non-fl at area of the blade. If this
happens, try rotating the blade
1
⁄
4
turn and retesting. Repeat this process until you get a reading that is not
signifi cantly affected by blade fl atness. If you cannot get a good reading, try a different blade.
If there is a gradual and continuous change in the dial reading of over 0.002 inch in either the positive or
negative direction, rotate the blade
1
⁄
2
turn. Slide the dial indicator mount back toward the front of the blade
and reset the indicator to zero. Now slide the mount toward the back of the saw again while noting the dial
reading. If there is similar change but in the opposite direction, this indicates that the left and right surfaces of
the blade are not parallel. Rotate the blade
1
⁄
4
turn and repeat the process from the beginning. If you cannot
get consistent readings, try a different blade.
If the dial indicator reads a relatively consistent difference between the front and rear of the blade, take the
average of the readings. A measurement of 0.002 inch or less indicates that the table is aligned within the
margin of error for this measurement and no further alignment is necessary. For measurements larger than
0.002 inch, you can adjust the position of the table to improve the parallelism between the blade and the miter
slot.
