Application
This unit describes the performance outcomes required to inspect, service and repair faults in pneumatic systems and components. It involves preparing for the task, inspecting the system to determine the service and repair requirements, carrying out the service and repair, performing post-repair testing, and completing workplace processes and documentation.
It applies to those working in the automotive service and repair industry. The pneumatic systems include those of agricultural machinery, heavy commercial vehicles or mobile plant machinery. Work includes compressors, linear or rotary actuators, drive motors, conductors and control valves.
No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.

Assessment Conditions
Assessors must satisfy NVR/AQTF assessor requirements.
Competency is to be assessed in the workplace or a simulated environment that accurately reflects performance in a real workplace setting.
Assessment must include direct observation of tasks.
Where assessment of competency includes third-party evidence, individuals must provide evidence that links them to the pneumatic systems that they have serviced and repaired, e.g. repair orders.
Assessors must verify performance evidence through questioning on skills and knowledge to ensure correct interpretation and application.
The following resources must be made available:
automotive repair workplace or simulated workplace
workplace instructions
manufacturer pneumatic system specifications
two different vehicles or machinery with pneumatic systems requiring service and repair
tools, equipment and materials appropriate for inspecting, servicing and repairing pneumatic systems.
