Just got this machine w/out instruction manual so i have no idea about the ground balancing , and the retune switch what it is for. Also tune norm/auto. I turn on machine and in all metal threas does not go on until i turn to 3:00 position and does not sound loud at all, even turned all the way clockwise. This is my first tesoro machine , so easy on me lol. Thanks in advance for any info. GS
