Disengage the head lockpin (yellow) and move the indicator away from the target.11.36 Proceed with cutting the rotor.Note: It is not necessary to make another scratchcut because the cutter head has not moved significantlysince the lock pin (yellow) was re-enaged.11.4 Switch power ON. With both cutting tipsbacked away from the rotor, advance the carbideinserts toward the center of the rotor diameter, usingthe feed handwheel, being careful not to run the carbideinserts into the hub portion of the rotor.11.5 Reposition carbide inserts to the cleanupposition by turning each insert adjustment knob clockwiseone revolution, plus 0.004-inch cut depth forresurfacing each side of the rotor. Make sure the toolholder locking levers are locked in place before engagingfeed.Completing the CutCAUTIONFor optimum results, once the automaticfeed is engaged, do not disturb the lathe orstand during the cut or damage to the rotormay result.12.0 Engage feed by pushing the feed engagementknob (gray) forward into the slots.
