Adjustments WARNING: Before performing any adjustment, make sure the tool is unplugged from the power supply. Failure to heed this warning could result in serious personal injury. WARNING: Blades coast after turn off. Possible serious injury can occur if hands come in contact with blade. The table saw has been adjusted at the factory for making very accurate cuts. However, some of the components might have been jarred out of alignment during shipping. Also, over a period of time, readjustment will probably become necessary due to wear. To avoid unnecessary set-ups and adjustments, a good practice is to check your setups carefully with a framing square and make practice cuts in scrap wood before making finish cuts in good workpieces. Do not start any adjustments until you have checked with a square and made test cuts to be sure adjustments are needed. TO REPLACe THE BLADE See Figures 43 - 45.  Unplug the saw.  Lower the saw blade, raise the blade guard, and remove the throat plate.  Make sure the bevel locking lever is securely pushed to the left. Raise the saw blade to its full height by turning the height/bevel adjusting handwheel clockwise.  Using the smaller hex wrench, insert the flat open end into the flats on the arbor shaft.  Insert the closed end of the larger hex wrench over the hex nut. Holding both wrenches firmly, pull the larger wrench forward to the front of the machine. Make sure the blade nut is securely tightened. Do not overtighten. Check all clearances for free blade rotation. See To Set the Scale to the Blade. In cutting operations, the scale will be set to the side of the blade where the cut will be measured and made. To replace the blade with an accessory blade, follow the instructions provided with the accessory. To install a standard blade:  Place the new blade on the arbor shaft (the teeth must point down toward the front of the saw to work properly).  Place the blade washer and the blade nut over the blade arbor. Be sure the dome side of the blade washer faces out from the blade and that all items are snug against the arbor housing. Tighten securely.
