My dealer told me that if I get an Out of Stroke error message, I will need to reset the control panel or it will continue to glitch in the future. You reset the panel by hitting the Retract All button. After this the controls should work satisfactorily. The only time I have had Out of Stroke messages is when I had any of the jacks not able to extend far enough. Using more blocks has always corrected the problem.
