ASSEMBLY TO CHECK SAW BLADE INSTALLATION See Figure 13. NOTICE: To work properly, the saw blade teeth must point down toward the front of the saw. Failure to do so could cause damage to the saw blade, the saw, or the workpiece.  Unplug the saw.  Lower the saw blade and remove the throat plate.  Make sure the bevel locking lever is securely pushed to the right. Raise the saw blade to its full height by turning the height/bevel adjusting handwheel clockwise.  Place riving knife in "up" position. To loosen the blade:  Using the open end blade wrench, place the flat open end on the flats on the arbor shaft.  Insert the closed end blade wrench over the blade nut. Holding both wrenches firmly, pull the closed end wrench forward to the front of the machine. To tighten the blade:  Using the open end blade wrench, place the flat open end into the flats on the arbor shaft.  Insert the closed end blade wrench over the blade nut. Holding both wrenches firmly, push the closed end wrench to the back of the machine. Make sure the blade nut is securely tightened. Do not overtighten.  Reinstall the throat plate.  Check all clearances for free blade rotation. OPEN END BLADE WRENCH CLOSED END BLADE WRENCH BLADE NUT Fig. 13 19
