A motor grader, or road grader, is a self-propelled earthmoving machine with an adjustable blade between the front and rear axle. The blade is most commonly used for cutting, spreading and levelling of material. HRETD’s short skills grader training course has been developed for the benefit of novices and experienced operators who may be expected to do grading operations while performing their daily duties in the construction and earthmoving plant industries.
This unit standard forms part of the National Certificate: Construction Plant Operations (SAQA ID 65789). Learners who achieve the course objectives will, upon completion of the course, contribute to the development of a professional community of construction plant operators.
Entry requirements
Grade 9 certificate or ABET level 4 is required to attend this course and a code B national driver’s license if mandatory, if operating on South African roads in accordance with The National Road Traffic Act 93 of 1996.

Course contentIntroduction
We explain what a grader is, give a list of different makes of graders, explain the grader’s functions, list different types of PPE and explain why personal protective equipment is so important.
Grader components and structure familiarisation
We identify the different components found on a grader, the external and internal components of a typical grader engine, explain the difference between petrol and diesel engines and we discuss how the following components function - hydraulic, electrical, cooling and braking systems, power train and tyres.
Gauges and warning devices
We explain the different types of gauges, warning devices, the different warning levels found on electronic and computer monitoring systems, identifying the different symbols found thereupon.
Grader controls
We explain why the operator’s compartment must be kept clean, neat and tidy, the function of the floor pedals, direction control function, steering control and the implementation of such functions.
Grader checks
We list and explain why the operator must perform and complete different machine checks and explain how to stop, shut down and park the machine.
General grader safety
We explain who is responsible for the operator and machine’s safety and list general and site safety rules.
Grader operating techniques
We explain how to perform all the basic grader operations safely, list the different operating techniques; explain what the different engine smoke colours indicate, why intermittent revving is not desired and how to start a cold engine.
Transporting the grader
We explain how to safely load the grader onto a transporter, what aspects to check for while loading and off-loading the grader, how to off-load the grader from the transporter and how to position and secure the grader on the transporter.
Assessment methods
We conduct a formative theoretical assessment at the beginning of the course to gauge the learner’s initial understanding (novices only). At the end of the training, a summative theoretical and practical application assessment is conducted, to find if the learner is competent; if not, additional developmental areas are identified and suggested.
