Adjusting the Pulsing Power of the Auto Trim valve

The Auto Trim valve is factory set to full pulsing power, that is, the length of N is set according to the table, refer to Length of "L" and "N" for different tool sizes

To improve accuracy (more pulses before shut off) on hard or medium hard joints, reduce the power. The power is reduced by turning the nut (1) clockwise (increased length of N).
