Description
Employability Skills
Learning Outcomes and Application This unit describes the performance outcomes required to diagnose and repair faults in the spark ignition and compression ignition engines of outdoor power equipment. 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 engines include those in outdoor power equipment. This unit does not apply to light or heavy vehicles.No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

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 outdoor power equipment engines 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 outdoor power equipment engine specifications

different types of outdoor power equipment engines specified in the performance evidence

diagnostic equipment for outdoor power equipment engines

tools, equipment and materials appropriate for diagnosing and repairing outdoor power equipment engines.
