8.3 AIR SHUTOFF VALVE (ASOV) (IF EQUIPPED)
A. Air Shutoff Valve Test
Air Shutoff Valve (ASOV) is an overspeed protection device mounted to the engine’s air
intake system. When the valve is actuated, it obstructs airflow intake and stops the
engine. Weekly tests are recommended to ensure the valve remains in good working
condition.
1. Start the engine, running at idle.
2. Open the red switch guard of ASOV test switch, then activate toggle to test mode
(see page 3 - 2).
3. Rev the engine in neutral until the valve actuates at the test RPM of 1500. Once valve
actuates, engine will stop.
4. Turn ignition to OFF.
5. Visually inspect valve to ensure it appears in good condition.
6. Reset valve by rotating valve handle to the Open position.
Note:
The handle cannot be turned unless the machine is off. Ensure the ignition is moved to
the OFF position.
WARNING
Do not use ASOV as an alternative to shutting down machine properly.
