Service Information
Service Schedule
The manufacturer recommends that the following service procedure should be performed at each machine’s
scheduled service interval.
Service Procedure
1. Perform a visual inspection and include the following:
a) Control unit
b) Wiring connections and looms
c) All switches and sensors as below
d) Engine fluids
2. Perform a system test as per the following:
a) Refer to the Operation and Use section of this manual for the operation of the control unit and each
function.
b) Test each circuit individually as per the Test Procedure.
Note: All monitoring switches should be changed when fitting a new or repaired engine to a machine.
Coolant Level Sensor
Every 2000 hours or six months
1. Remove the sensor from the radiator.
2. Plug the hole to minimise coolant loss.
3. Inspect the condition of the sensor ensuring the centre of the sensor is insulated from outer mounting.
Ensure the sensor is free from grease, oil, and dirt.
4. Inspect electrical connection point for thread damage, burrs, corrosion and ensure the nut tightens on the
thread (if applicable).
5. Refit the sensor ensuring the thread is free from coolant leaks.
Engine Oil Pressure Switch
Every 2000 hours or six months
1. If engine oil faults are present and tests performed on the electrical circuit prove inconclusive, it is
recommended that the engine oil pressure switch be replaced.
2. Due to the critical function of this switch, it is recommended that the engine oil pressure switch be replaced
every 2000 hours or every six months.
Engine Temperature Switch
Every 2000 hours or six months
1. If temperature faults are present and tests performed on the electrical circuit prove inconclusive, it is
recommended that the coolant temperature switch be replaced.
2. Due to the critical function of this switch, it is recommended that the coolant temperature switch be replaced
every 2000 hours or every six months.
Oil/Fuel Level Switch
Every 2000 hours or six months
1. It will be necessary to remove the switch for testing.
2. Remove switch and plug hole to prevent fluid loss.
3. Inspect the switch for physical damage.
4. Reconnect the 3-pin Deutsch plug.
5. Turn the ignition switch to the ON position.
6. Verify the oil/fuel level alert indicator is now illuminated.
7. Immerse the threaded end of the switch in oil and verify that the oil/fuel level alert indicator is no longer
illuminated.
8. If the switch tests okay, refit the switch using thread sealant.
