This unit describes the performance outcomes required to diagnose and repair faults in the pumping systems of outdoor power equipment according to manufacturer specifications. It involves preparing for the task, selecting the correct diagnostic procedure, carrying out the diagnosis and the repair, performing post-repair testing, and completing workplace processes and documentation.
It applies to those working in the automotive service and repair industry. The pumping systems are those of outdoor power equipment and include:
centrifugal pumps used for firefighting, irrigation and water transfer
diaphragm pumps used in orchard spraying
high pressure piston pumps used for pressure cleaners
No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.
You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)
