The low shaft speed monitor shows with lights and a buzzer when beater, straw chopper, grain separator, auger conveyor, grain elevator and tailings elevator are operating less than 85 percent of their designed speed.

NOTE: The electric clutch and low shaft speed monitor are both on the same circuit.

To check operation of monitor, turn key to "ON" (do not start engine) and engage separator and header drive switches. All lights must turn on and buzzer must sound. If they do not, see "Low Shaft Speed Monitor Troubleshooting" in this Section.

If all the lights come on and the buzzer sounds, start engine, engage separator and header drive switches and run engine at fast idle.

If lights continue to stay on, disengage separator and header switches and idle engine. Shut off engine, remove key, and see "Troubleshooting" Section.

CAUTION: Shut off engine and remove key before working on combine.

IMPORTANT: The sensors are not adjustable. If combine is not equipped with a straw chopper, be certain sensor leads are connected to ground plugs to prevent a false alarm.
