Application

This unit describes the skills and knowledge required to service and repair faults in the chainsaw cutting systems of outdoor power equipment according to manufacturer specifications. The unit 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.
The unit 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

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
• equipment stands and vices
• grinders
• chain breaking and riveting equipment.
Assessors of this unit must satisfy the requirements for assessors in applicable vocational education and training legislation, frameworks and/or standards.
