Application
This unit describes the performance outcomes required to inspect and service pumping systems according to manufacturer instructions. 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 outdoor power equipment service and repair industry. The pumping systems include centrifugal pumps used for firefighting, irrigation and water transfer, high pressure piston pumps used for pressure cleaners, or diaphragm pumps used in orchard spraying.
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 pumping 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:
outdoor power equipment repair workplace or simulated workplace
workplace instructions
manufacturer specifications for pumping systems
three pumping systems specified in the performance evidence and requiring servicing
tools, equipment and materials appropriate for inspecting and servicing pumping systems.
