Limit Switches

 As you can see, there are limit switches at the top, at the bottom, and between the saws. We use these to prevent the saw collars from being rammed into the bearings at the top and bottom and together in the middle. Without these limit switches there would be a lot of unnecessary wear on the guide arm bushings and the saw collars from the cocking that would be created as well as the extra heat that is created every time the hydraulic system goes over the pressure relief. The limit switches also play a part in the system the sawyer uses to clear the saws until he has another log ready for edging.   Limit Switches
