Application
This unit describes the performance outcomes required to inspect and service hydraulic systems. It involves preparing for the task, inspecting the system, reporting the inspection findings, servicing and adjusting the system, and completing workplace processes and documentation.
It applies to those working in the automotive service and repair industry. The hydraulic systems include those of agricultural machinery, heavy commercial vehicles, marine vessels, mobile plant machinery or outdoor power equipment. This unit is not intended for drive systems, power steering or hydraulic braking systems.
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 hydraulic systems that they have worked on, 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 hydraulic system specifications
- AS 1101.1 Graphic symbols for general engineering, Part 1: Hydraulic and pneumatic systems
- two different hydraulic systems requiring servicing
- tools, equipment and materials appropriate for the inspection and servicing of hydraulic systems.
