Application
This unit describes the performance outcomes required to inspect and service line trimming systems and components according to manufacturer instructions. It involves preparing for the task, inspecting the system and components, reporting the inspection findings, servicing and adjusting the system and components, and completing workplace processes and documentation.
It applies to those working in the outdoor power equipment service and repair industry. The line trimming systems include brush cutters and grass trimmers which may be electric or petrol driven, stand-alone or fitted to other equipment 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 line trimming systems and components 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 line trimming specifications
outdoor power equipment line trimming system and components specified in the performance evidence and requiring servicing
tools, equipment and materials appropriate for inspecting and servicing line trimming systems and components.
