Adjusting the reduced speed of the Auto Trim valve

The Auto Trim valve is factory set to approximately 70% of full speed. To decrease the speed, decrease the length of L. To increase the speed, increase the length of L.

Turn the support ring (1)to adjust the length of L.

On very hard joints (<30°) at low torque levels, further speed reduction might be necessary. When the tool is used only on soft joints, less or no speed reduction is needed.

The factory set length of L is depending on the tool size, refer to Length of "L" and "N" for different tool sizes
