You can easily obtainthree different depths of cut using these adjusting hexbolts without readjusting the stopper pole.Adjust the lowest hex bolt to obtain the deepest depthof cut, following the method of "Adjusting depth of cut".Adjust the two remaining hex bolts to obtain shallowerdepths of cut. The differences in height of these hexbolts are equal to the differences in depths of cut.To adjust the hex bolts, turn the hex bolts with a screwdriver orwrench. The stopper block is also convenient for making three passeswith progressively deeper bit settings when cutting deep grooves.CAUTION:• Since excessive cutting may cause overload of themotor or difficulty in controlling the tool, the depthof cut should not be more than 15 mm at a passwhen cutting grooves with an 8 mm diameter bit.• When cutting grooves with a 20 mm diameter bit, thedepth of cut should not be more than 5 mm at a pass.• For extra-deep grooving operations, make two orthree passes with progressively deeper bit settings.Switch action12► 1.
