OPERATION HEELING (PARALLELING) THE BLADE TO THE MITER GAUGE GROOVE See Figures 34 - 35. WARNING: The blade must be parallel to the miter gauge groove so the wood does not bind resulting in kickback. Failure to do so could result in serious personal injury. Do not loosen any bolts for this adjustment until you have checked with a square and made test cuts to be sure adjustments are necessary. Once the bolts are loosened, these items must be reset.  Unplug the saw.  Remove the blade guard and anti-kickback pawls.  Mark beside one of the blade teeth at the front of the blade. Place a framing square even with the front of the saw table and the side of the saw blade as shown in figure 34.  Turn the blade so the marked tooth is at the back.  Move the combination square to the rear and again measure the distance. If the distances are the same, the blade is square. If the distances are different:  Extend the extension table, see page 27.  Place riving knife in "down" position.  Loosen the locking bolts by turning towards the left. NOTE: The bolts are located above the height/bevel adjusting handwheel and under the saw table in the front of the saw.  Turn adjusting bolt left or right until the blade is square.  Tighten the locking bolts. Check again for squareness and continue to adjust if needed. WARNING: To reduce the risk of injury from kickback, align the rip fence to the blade following any blade adjustments. Always make sure the rip fence is parallel to the blade before beginning any operation.
