Im told that holding the 2nd ls switch overides the overlimit but it dosent work for me..... I manually turn the screw untill its off the switch and then re start the machine Ive done this several times with our kitamura mycenter1
if the machine is not in overtravel and you acttivated the switch and it wont come out of lock even if you restart the switch is probably stuck so take the switch apart and find the problem
take care
