Low Shaft Speed Monitor (General Information)

Low shaft speed monitor warning lights (A) come ON and a buzzer sounds when the feed accelerator, chopper, discharge beater, auger conveyor, grain elevator, tailings elevator and premium straw chopper (if equipped) are operating less than 85% of the normal speed.

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

To check operation of monitor warning lights, turn key switch to ON position (do not start engine) and engage separator and header drive switches. All lights must turn ON and buzzer must sound.

If all lights come ON and 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, set parking brake and remove key (see Low Shaft Speed Monitor Troubleshooting).

CAUTION: Shut OFF engine, set parking brake and remove key before working on combine.

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