USE THE NUT DRIVER TO LOOSEN THE NUT AND QUICKLY CHANGE BLADES
The saw blade is changed by lowering the blade and arbor assembly all the way so that the blade will clear the table when it is removed. Use the nut driver to loosen the nut that holds the saw , remove the saw and replace it . Make sure the teeth are pointing toward the back of the saw table. Tighten the saw with the nut driver which provided the right amount of torque to hold the blade without making the nut so tight it is difficult to remove next time you change the blade.
The Nut Driver costs $8.00 .
