Loosen the two locking screws on the bar. 2. Turn the adjusting screw in the positive direction until it becomes snug. The adjusting screw becomes snug when it locks the tuner mass. 3. Turn the screw one complete turn in the negative direction and take a test cut. 4. Repeat Step 3 until chatter is eliminated. 5. Once chatter is eliminated, note that chatter starts between the current screw setting and one turn in the positive direction. Make 1/4 turn adjustments within this range, taking test cuts for each setting, until you can identify the adjusting screw setting that causes chatter to start. 6. Once the adjusting screw setting that causes chatter is determined, back the adjusting screw off a 1/2 turn in the negative direction. 7. Tighten both clamping screws and take a test cut to confirm desired results. widia.com C83
