6Stopper blockThe stopper block has three adjusting hex bolts which raise or lower 0.8 mmper turn. You can easily obtain three different depths of cut using these adjust-ing hex bolts without readjusting the stopper pole.Adjust the lowest hex bolt to obtain the deepest depth of cut, following themethod of “Adjusting depth of cut”. Adjust the two remaining hex bolts toobtain shallower depths of cut. The differences in height of these hex bolts areequal to the differences in depths of cut.To adjust the hex bolts, first loosen the hex nuts on the hex bolts with thewrench and then turn the hex bolts. After obtaining the desired position,tighten the hex nuts while holding the hex bolts in that desired position. Thestopper block is also convenient for making three passes with progressivelydeeper bit settings when cutting deep grooves.CAUTION:When using a bit having total length of 60 mm or more, or edge length of 35mm or more, the depth of cut cannot be adjusted as previously mentioned. Toadjust, proceed as follows:Loosen the lock lever and carefully adjust bit protrusion below the tool base tothe desired depth of cut by moving the tool body up or down. Then retightenthe lock lever to lock the tool body at that depth of cut. Keep the tool bodylocked at this position during use. Since the bit always protrudes from the toolbase, be careful when handling the tool.Adjusting the lock leverThe locked position of the lock lever is adjustable. To adjust it, loosen the locklever 3/4 turn and press the center of the lock lever. The hex nut will come out.Set the hex nut to the desired position and tighten the lock lever.Switch actionCAUTION:• Before plugging in the tool, always check to see that the switch triggeractuates properly and returns to the “OFF” position when released.To start the tool, simply pull the switch trigger.
