Servicing the AutoTrim Valve
Make sure all parts are clean. O-rings should be lightly greased. Valve and bracket should be sparsely oiled with light oil. Make sure that the valve moves easily on the bracket. When adjusting the throttle valve, start from fully closed position (clockwise) and open between 6-8 turns. Check and adjust again if needed.
Check and adjust the lengths of L and N corresponding to the ordering number of the AutoTrim valve (as of 2008 the ordering number is engraved on the AutoTrim casing). See Adjusting the Free Speed and Adjusting the Pulsing Power.
Test the valve function on the corresponding EP tool. Change the filter regularly to prevent clogging, decreased power, and incorrect function.
