DeWalt 28-682 Saw User Manual


 
The lower bearing adjustments are similar to the upper bearing
adjustments. Adjust the blade support bearing (A) Fig 23 so that
it is within 1/64” of, but not touching the back of the saw blade
when the blade is at rest. To adjust, loosen hex screw (B) and slide
the bracket in or out until the adjustment is correct. Tighten the
screw. Adjust the blade guide bearings (C,G) by loosening the
screw (E) and rotating the bearing on the shaft (F) so that the
bearings touch, but do not pinch the blade. To gain access the
back bearing (G), you will need to remove the table insert and tilt
the table to the right. Return table to level position. The front edge
of the guide bearings (C) should be just behind the “gullets” of the
saw teeth. To adjust, loosen the hex screw (D) and slide the bearing assembly into place. Tighten the hex screw (D).
