Description
This unit covers the process of non-company specific service and repair of milking equipment on farm so as to meet prescribed maintenance schedules or to rectify poor performance and defines the standard required to monitor and evaluate the performance of milking equipment; operate the full range of milking equipment components; carry out mechanical testing of milking equipment; apply information from operator's manuals and supplied maintenance and diagnostic data; disassemble and re-assemble a range of milking equipment components such as pulsators, regulators and vacuum pumps.

Elements and Performance Criteria
1. Service and repair vacuum pumps and the vacuum regulator
- 1.1. Vacuum pump capacity is established as a part of mechanical testing and performance assessed against design parameters and shed requirements.
- 1.2. Vacuum pump is disassembled, serviced and reassembled.
- 1.3. Vacuum pump exhaust and housing is checked and repaired as required to minimise noise and ensure that levels remain within prescribed workplace standards.
- 1.4. Regulators are checked for performance cleaned and defective parts replaced.
2. Service pulsators and electronic systems
- 2.1. Pulsator performance is assessed during milking and as a part of mechanical testing.
- 2.2. Electronic or pneumatic pulsators are removed and repaired or replaced as identified in mechanical testing.
- 2.3. Extra low voltage segments of the pulsation and wash systems controllers are tested and replaced as required.
3. Service and repair milk pumps and the milk releasing system
- 3.1. Milk pumps are checked for pumping performance.
- 3.2. Milk pumps are disassembled and repairs as required including drives and couplings.
- 3.3. Milk releaser is inspected and checked with rubber seals and flaps replaced as required.
4. Repair and maintain the milk transport system
- 4.1. Rubberware is inspected for correct specification including liner/teat cup matching and replaced or adjusted as required.
- 4.2. Claws and claw bowls are inspected for cleanliness and correct connection to suit the specific pulsation system.
- 4.3. The operation of automatic vacuum cut-off in the claw is assessed and air admission holes cleaned as required.
- 4.4. Milk lines and air lines are inspected and joins checked for compliance with industry minimum standard recommendations.
- 4.5. Cans and vessels are checked for dents and damage and shut off valves checked for correct operation.
- 4.6. Plate cooler is disassembled, cleaned and re- assembled and filters cleaned and replaced as required.
5. Service and repair non-milking systems
- 5.1. Jetters and cleaning system are inspected to ensure adequate air admission during cleaning and correct water volumes are circulating.
- 5.2. Repairs or replacement of cleaning system components are effected as required
- 5.3. Automatic cup removers are checked to ensure that detectors are clean and effective and that the pistons operate effectively.
- 5.4. Automatic cup removers are repaired or replaced as required.
- 5.5. Herd recording equipment is inspected and valves and rubberware replaced as required.
- 5.6. Feed systems are inspected and repaired or maintained as required.

EVIDENCE GUIDE
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:
monitor and evaluate the performance of milking equipment
operate the full range of milking equipment components
carry out mechanical testing of milking equipment
apply information from operator's manuals and supplied maintenance and diagnostic data
disassemble and re-assemble a range of milking equipment components such as pulsators, regulators and vacuum pumps.
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.
