Elements and Performance Criteria

1. Identify faults in milking machines
   • Occupational Health and Safety (OHS) hazards are identified, risk assessed and recorded.
   • Poor performance of milking equipment is identified from observations at milking.
   • Minor machine adjustments are carried out to rectify identified poor performance characteristics.
   • Fault finding and fault diagnosis is completed with minimum disruption to milking routines.
2. Identify external faults
   • Independent electrical appliances that impact on the farm dairy operation are identified and isolated.
   • Animal behaviour during milking is observed and recorded to identify abnormalities.
   • Earthing systems and grids are installed to minimise potential differences in the milking shed.
3. Carry out operational service&maintenance of milking machines
   • Machine components are cleaned, adjusted and defective parts or components repaired or replaced to bring machine up to industry performance standards.
   • Defective electric motors are disconnected, removed and replaced to conform to manufacturer's recommendations and OHS guidelines.
   • Programmed maintenance routines are completed to replace consumables and maintain lubrication in accordance with manufacturer's recommendations.
   • OHS hazards identified in safety audits are eliminated or risk controlled according to manufacturer's guidelines and industry standards.
   • Adjustments are completed to restore optimum performance of milking equipment.

Evidence Required

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria required skills and knowledge range statement and the Assessment Guidelines for the Training Package
Overview of assessment
Critical aspects for assessment and evidence required to demonstrate competency in this unit	The evidence required to demonstrate competency in this unit must be relevant to workplace operations and satisfy holistically all of the requirements of the performance criteria and required skills and knowledge and include achievement of the following observe and critically evaluate the performance of milking equipment operate the full range of milking equipment components identify common sources of air leakage operate hand tools and use a range of test equipment proficiently read and interpret operators manuals and maintenance data supplied disassemble and assemble a range of milking equipment components such as pulsators regulators
Context of and specific resources for assessment	Competency requires the application of work practices under work conditions Selection and use of resources for some worksites may differ due to the regional or enterprise circumstances
