You can easily obtain threedifferent depths of cut using these adjusting hex bolts withoutreadjusting the stopper pole.Adjust the lowest hex bolt to obtain the deepest depth of cut,following the method of “Adjusting depth of cut”. Adjust thetwo remaining hex bolts to obtain shallower depths of cut.The differences in height of these hex bolts are equal to thedifferences in depths of cut.To adjust the hex bolts, first loosen the hex nuts on the hexbolts with the wrench and then turn the hex bolts. Afterobtaining the desired position, tighten the hex nuts whileholding the hex bolts in that desired position.
