HOT ENGINE COMPONENTS CAN CAUSE SERIOUS BURNS. SHUT THE ENGINE DOWN AND ALLOW IT TO COOL BEFORE WORKING IN THE ENGINE COMPARTMENT.
With the engine running, note the system pressure gauge. The pressure should be 95 to 110 psi (655 to 758 kPa). If it is necessary to adjust the governor cut-out pressure: 1. SHUT THE ENGINE DOWN, remove the protective rubber cap from the governor, loosen the jam nut, insert a screwdriver into the slot of the adjusting screw and turn the adjusting screw slightly. Turning the adjusting screw clockwise will raise the cut-out pressure. Turning the adjusting screw counterclockwise will lower the cut-out pressure.2. Tighten the jam nut. 3. Start the engine and check the pressure gauge reading. Repeat steps 1 through 3 until the cut-out pressure is correctly adjusted.4. SHUT THE ENGINE DOWN. Check to be sure the jam nut is tight and replace the protective rubber cap.Repair Procedures
