Each piece of machinery will have its own set of alarms, monitoring systems and gauges to assist the driver in the effective and efficient operation of the vehicle.
Some of the alarms, gauges, and monitoring systems you may find on a piece of machinery could include:
• Brake Monitors – air pressure, oil temperature, parking alarms.
• Temperature Gauges – oil, water.
• Filters – fuel, steering, transmission.
• Engine Gauges – fuel, engine oil pressure.
• Gauges And Meters – tachometer, torque converter, voltmeter, speedometer, odometer, service meter, retarder.
For a list of the specific gauges, alarms, and monitors on the scraper you are operating, refer to the operator’s manual.
If an alarm, gauge, or monitoring system shows that something is wrong or not working within the specified range, you must stop your machine and respond to the alarm in an appropriate manner. It is essential that you stop the machine in a safe and controlled manner, and that this is communicated to any other relevant personnel working within your area. Some work sites will need you to remove your scraper to a designated maintenance area before stopping.
The response required from the operator will be dependent upon the type of alarm, gauge or monitoring system that is indicated.
Basic Warnings
Basic Warnings to fill your fuel or oil, check your speed or arrange servicing of the vehicle can be attended to as soon as practical or possible without danger.

Other Alarms
Other alarms require an immediate response to minimise the risk of danger. For example, a sudden drop in oil pressure could indicate a broken or leaking hose. In these cases the machinery will need to be removed from the work area, reported immediately to your supervisor, and fixed by either the operator or a mechanic. If you are unsure about the meaning of an alarm, gauge or monitoring system check your operator’s manual, and talk to colleagues or your supervisor.
In all cases, any faults found on your scraper must be reported in writing or verbally. The work site induction will outline the particular requirements for each individual site you work on.
