Service and repair chainsaw cutting systems


Application

This unit describes the performance outcomes required to service and repair faults in the chainsaw cutting systems of outdoor power equipment according to manufacturer specifications. It involves preparing for the task, determining the service and repair requirements, carrying out the service and repair, performing post-repair testing, and completing workplace processes and documentation.

It applies to those working in the outdoor power equipment service and repair industry. The chainsaw cutting systems include those of electric, cordless and hydraulic or petrol powered systems, or pole saws.

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 chainsaw cutting systems that they have serviced and repaired, 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 chainsaw cutting systems

area and equipment, including PPE, required to safely test chainsaw cutting systems

three different chainsaw cutting systems requiring service and repair

tools, equipment and materials appropriate for inspecting, servicing and repairing chainsaw cutting systems, including:

sharpening equipment

saw chain
