Benchmark specifications for correctly functioning wheeled mobile plant steering and suspension systems are accessed and interpreted. 1.3. OH&S requirements, including equipment and system isolation requirements and personal protection needs are observed throughout the work. 1.4. Effects of systemic deficiencies/discrepancies or faults are identified and confirmed from indirect and/or direct evidence. 1.5. Possible safety impacts of the work are considered and responded to in accordance with regulatory and enterprise obligations and practices. |
2. Prepare for analysis and evaluation |
2.1. Evaluative criteria are developed/adopted to meet the objective of the work. 2.2. System performance achievements and/or discrepancies are identified from an analysis of technical support information and available on-board diagnostic systems. 2.3. Analytical and evaluative methodology, including diagnostic process, sequence, tests and testing equipment are developed and/or identified and selected from the range of available options. 2.4. Testing equipment is obtained and prepared for application in accordance with regulatory, manufacturer/component supplier and enterprise requirements. 2.5. Tooling and materials required to support the diagnostic process are identified, selected and prepared for use. 2.6. Wheeled mobile plant steering and suspension system components are prepared for the diagnostic process, including park-up, isolation and cleaning requirements. |
3. Apply the analysis and evaluative methodology |
3.1. Selected analytical and diagnostic process is followed in accordance with specifications and directions and/or the locally authorised method. 3.2. Tests and testing equipment are applied in accordance with regulatory requirements and manufacturer/component supplier specifications. 3.3. Analytical and other diagnostic findings are verified, if necessary, by using reliable alternate or optional processes, and documented. 3.4. Analytical findings and results are evaluated against the agreed criteria. 3.5. Valid conclusions are drawn from the available evidence and documented to enterprise requirements. 3.6. Information and detail related to the analysis and evaluation is provided to the appropriate parties in accordance with regulatory and commercial obligations. |
4. Select response measure |
4.1. Options for responding to the objective or need are identified from further research of technical support information. 4.2. A response option is selected from an analysis of the options, prevailing circumstance, regulatory requirements and commercial policies. 4.3. Selected response option is documented and reported in accordance with regulatory and enterprise requirements and practices. |
5. Restore the workplace |
5.1. Materials that can be reused is collected and stored. 5.2. Testing equipment and other support materials are cleaned, maintained and prepared ready for further use or stored in accordance with manufacturer/component supplier specifications and enterprise requirements. 5.3. Waste and scrap is removed following workplace procedures. 5.4. Equipment and work area are cleaned and inspected for serviceable condition in accordance with workplace procedures. 5.5. Unserviceable equipment is tagged and faults identified in accordance with workplace. |

Overview of assessment |
|
Critical aspects for assessment and evidence required to demonstrate competency in this unit |
|
Context of , and specific resources for assessment |
Assessment may occur on the job or in a workplace simulated facility with process equipment, material, work instructions and deadlines. Access to a requirement and objective(s) for analysis and evaluation, wheeled mobile plant steering and suspension systems with real or simulated faults, monitoring processes and testing equipment appropriate to the objective(s), research facilities and technical information and a work environment. |
Method of assessment |
Assessment of this unit of competence is most likely to be project related under real or simulated conditions and require portfolios or other forms of indirect evidence of process. Direct evidence may include certification of compliance of the final outcome/product or authorisation for use by a competent authority. Assessment must confirm the inference that competence is able not only to be satisfied under the particular circumstances, but is able to be transferred to other circumstances. Competence in this unit may be assessed in conjunction with other functional units which together form part of the holistic work role. |
Guidance information for assessment |
Range Statement
RANGE STATEMENT |
|
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included. |
|
