The horizontal stop screw limits the downward travel of the saw bow to keep the blade from running into the cast iron bed. The stop screw is located on the saw bow just next to the left hand blade wheel cover. See Figure 7.
Lower the saw bow by opening the feed rate valve. Stop the bow when the teeth are just 1⁄8'' below the top surface of the bed. Adjust the stop screw so it touches the bed surface. Tighten the locknut on the stop screw.

The motor should shut off immediately after the blade has cut through the material and just before the head comes to rest on the horizontal stop screw. The automatic shut off limit switch is located near the saw bow pivot point next to the hydraulic cylinder. See Figure 8.
Turn the saw on (after making sure the blade tensioning and tracking is correct), and lower the saw bow slowly. The saw should turn off just before the saw bow hits the stop screw. If it does not shut off at the proper point, the limit switch needs adjustment.
Loosen the two screws holding the limit switch bracket, and raise or lower the switch until the proper shut off point is achieved. If the switch is manually depressed, you will hear a click at the point the switch is being activated. You can use this activation point to set the switch in the proper position without the saw power being on.
After positioning the switch, double check its operation to make certain it is shutting off the blade just before contacting the horizontal stop screw.
