[. . . ] Demonstrations of all operations with the sights and sounds leading to successful drill bit sharpening · Service and contact numbers Again, thank you for buying a Drill Doctor®. For your own safety, please read this User's Guide before operating the Drill Doctor® . Always disconnect the Drill Doctor® when cleaning, inspecting, and changing accessories, such as the diamond sharpening wheel. Never touch internal parts of the sharpener when it is turned on or plugged in. [. . . ] Due to its additional cutting lips along the chisel edge, a split point will begin cutting immediately. Up to 70% less thrust (when compared to a non-split or conventional point) is required to drill a hole with a split point. If the machine quits removing material before the chisel is clean, re-align and sharpen again. The entire surface from the Cutting Edge to the Heel will have a finely ground surface without ridges or indentations. The Heel will always be lower than the Cutting Edge (positive relief). Leave bit in chuck after sharpening Always align and sharpen a bit before splitting it. To split the point, do not remove the bit from the Chuck after sharpening. To increase relief, insert the Alignment Guide on the Chuck closer to the (+) side of the Alignment Port, then sharpen the bit. Bit is backing out or slipping out of the jaws when you are sharpening. Chuck is too loose or you are using too much pressure when sharpening. Use more torque when tightening the Chuck or less pressure when sharpening. Making sure the Cam stays against Cam Guide, push the Cam Guide Chuck into the Sharpening Port Sharpening Port until it stops and tighten the Chuck. Short Drill Bits & Bit Smaller than 1/8" Put the bit in the Chuck as normal, but tighten Chuck so that it is just snug enough for the bit to move freely. Partially insert the Chuck in the Alignment Port, but do not push the Chuck all the way in. Use the Chuck Knob to rotate the bit until it can be held by the Bit Clamp Arms in the narrowest width of the bit. Make sure that the bit is touching the Drill Stop, then release the Alignment Button. Turn the Chuck until the Alignment Guide on the Chuck aligns with the 118º notch on the Alignment Port. Sharpen the small bit as usual, but use very light pressure and an even number of turns. Line up the Sharpening Guide on the chuck with the Cam Guide on the machine. Plunge the Chuck into the Sharpening Port until it touches the Sharpening Wheel. remove the Chuck , rotate one half-turn clockwise and repeat the plunge action. If the bit Cam stops grinding before the edges are sharp, loosen the Cam Guide Sharpening Guide Chuck, push the bit out slightly, tighten the Chuck, and continue sharpening. [. . . ] Sharpened drill bits burn or turn blue no matter how fast or slow you rotate the Chuck. When touching the Sharpening Wheel (with the machine unplugged), the lower portion feels too smooth (nonabrasive). When sharpening the drill bit, it takes too many halfturns to sharpen. With the Drill Doctor® unplugged, use your nail or the tip of your finger to pull the Wheel Access Cover down. [. . . ]
