Critical aspects of evidence
It is essential that competence in this unit signifies ability to transfer competence to changing circumstances and to respond to unusual circumstances in the critical aspects of:
observing safety procedures and requirements
communicating effectively with others involved in or affected by the work
selecting methods and techniques appropriate to the circumstances
completing preparatory activity in a systematic manner
conducting inspection in accordance with workplace requirements
interpreting inspection findings
carrying out service and repair to manufacturer/ component supplier requirements on a minimum of two different systems
completing service and/or repair of auxiliary braking systems and associated components within workplace timeframes
auxiliary braking system presentation to customer in compliance with workplace requirements
Relationship to other units
Competence in this unit may be assessed in conjunction with other functional units which together form part of the holistic work role
Underpinning knowledge
A working knowledge of:
OH&S regulations/requirements, equipment, material and personal safety requirements
importance of the role of auxiliary brakes and the necessity of working within manufacturer/component supplier tolerances and adjustments
operating principles of engine and exhaust brakes, hydraulic and electrical retarders and their component functions
types and layout of service/repair manuals (hard copy and electronic)
service procedures
repair procedures
enterprise quality procedures
work organisation and planning processes
Context of assessment
Application of competence is to be assessed in the workplace or simulated worksite
Assessment is to occur using standard and authorised work practices, safety requirements and environmental constraints
Assessment is to comply with regulatory requirements, including Australian Standards
Method of assessment
Assessment must satisfy the endorsed assessment guidelines of the automotive industry's RS&R Training Package
Assessment methods must confirm consistency and accuracy of performance together with application of underpinning knowledge
Assessment must be by direct observation of tasks, with questioning on underpinning knowledge and it must also reinforce the integration of key competencies
Assessment may be applied under project related conditions and require evidence of process
Assessment must confirm a reasonable inference that competence is able not only to be satisfied under the particular circumstance, but is able to be transferred to other circumstances
It is preferable that assessment reflects a process rather than an event and occurs over a period of time to cover varying quality circumstances. Evidence of performance may be provided by customers, team leaders/members or other persons subject to agreed authentication arrangements
Specific resource requirements for this unit
The following resources should be made available:
workplace location or simulated workplace
material relevant to the inspection, service and repair of auxiliary braking systems
equipment, hand and power tooling appropriate to the inspection, service and repair of auxiliary braking systems
activities covering mandatory task requirements
specifications and work instructions
