Adjusting the Free Speed
The AutoTrim valve is factory set to approximately 70% of full speed. To reduce the free speed, reduce the length of L. To increase the free speed, increase the length of L.
Adjust the length of L by turning the support ring (1).
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, see table.
