Blade ParallelismYour table saw will give the best results if themiter slot is parallel to the blade. If they are notexactly parallel, your cuts and finished work willbe lower in quality. To check and adjust bladeparallelism:1. Using an adjustable square, measure thedistance between the miter slot and the frontof your blade as shown in Figures 41 and42.2. Note the first measurement. Rotate theblade 180° and move the square to the rearof the blade. You may find it helpful to markyour blade with a felt-tip pen (as a rotationguide) at the point where the straightedgeand blade meet.3. Compare the measurements. If the differencein measurements is less than 0.004",your blade and table are in acceptable alignmentmove to Step 7. If the difference isgreater, you will need to adjust the trunnionand table.4. To adjust blade alignment, remove themotor, wings and the upper half of the sawfrom the stand. Place it upside down on 4 x4 blocks to allow the saw blade to rotatefreely.5. Remove the handwheels and the sheetmetal body. To maintain the trunnion assemblyas one unit, place a bar clamp across theentire trunnion assembly. The four trunnionbolts (Figure 43) can now be loosened. Thiswill allow the trunnion assembly to be shiftedin order to change the alignment betweenthe blade and the miter slot.Figure 41. 90° blade parallelism measurement.6. Now measure the miter slot to the blade asin Steps 1 and 2. Move the trunnion assemblyuntil proper alignment has beenobtained. Tighten the trunnion bolts andremove the bar clamp.#4 Shim LocationClamp Here#3 Shim LocationTrunnionBoltsTrunnionBoltsFigure 42. 90° blade parallelism measurement.#2 Shim Location#1 Shim LocationClamp HereFigure 43.
