The stopper block has three adjusting hex bolts which raise or lower 0.8 mm (about
1/32") per turn. You can easily obtain three different depths of cut using these adjusting
hex bolts without readjusting the stopper pole.
Adjust the lowest hex bolt to obtain the deepest depth of cut, following the method of
"Adjusting depth of cut". Adjust the two remaining hex bolts to obtain shallower depths
