Description
Employability Skills
Learning Outcomes and Application This unit describes the performance outcomes required to return outdoor power equipment engines to original manufacturer tolerances and clearances. It involves preparing for the task, dismantling and evaluating the engine, carrying out the overhaul procedures, reassembling and testing the engine, and completing workplace processes and documentation.It applies to those working in the outdoor power equipment and the engines may be two and four stroke spark ignition and four stroke compression ignition engines. The unit does not apply to light or heavy vehicle engines. This unit does not apply to light or heavy vehicle engines.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 workplace or simulated workplace

workplace instructions

manufacturer outdoor power equipment engine specifications

two different outdoor power equipment engines requiring overhaul

tools, equipment and materials appropriate for overhauling and adjusting outdoor power equipment engines.
