Application
This unit describes the performance outcomes required to inspect, service and repair faults in spraying and spreading equipment. It involves preparing for the task, inspecting the equipment to determine 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 automotive service and repair industry. The spraying and spreading equipment is that of agricultural machinery and refers to specialised equipment that may be self-propelled, trailed or three-point linkage, with controls for pressure, volume and coverage. It does not cover generalised equipment or systems that form the platform or the towing vehicle.
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 spraying and spreading equipment 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:
automotive repair workplace or simulated workplace
workplace instructions
manufacturer spraying and spreading specifications
one spraying equipment and one spreading equipment requiring service and repair
diagnostic equipment for spraying and spreading equipment
tools and equipment appropriate for inspecting, servicing, repairing and adjusting spraying and spreading equipment.
