REQUIRED SKILLS AND KNOWLEDGE 

This section describes the skills and knowledge required for this unit.

Required skills 

• collect, organise and understand legal and technical information related to contemporary gas fuel systems modifications.
• communicate ideas and information to enable confirmation of work requirements and specifications, coordination of work with site supervisor, other workers and customers, reporting of work outcomes and completion of regulatory, commercial and vehicle information systems inputs.
• plan and organise activities, including the development and planning of modification processes, preparation and layout of the worksite and the obtaining of tooling, equipment, materials and testing equipment to avoid backtracking, workflow interruptions or wastage.
• work with others and in a team by recognising dependencies and using cooperative approaches to optimise workflow and productivity.
• use mathematical ideas and techniques to complete measurements, calculate specifications, calibrate and establish testing equipment and evaluate modification results against pre-established criteria.
• establish modification methods and processes which anticipate and allow for risks and avoid or minimise reworking and avoid wastage.
• use the full range of workplace technology related to gas fuel systems modification, including testing equipment, maintenance equipment, tooling, calculators and measuring devices and information management systems.

Required knowledge 

• mechanical theory covering the concepts and principles of mechanical, hydraulic and pneumatic systems.
• general knowledge of the theory of diagnosis, including concept, design and planning.
• detailed knowledge of the concepts, types, functions, operations and limitations of gas fuel systems.
• detailed knowledge of the types, functions, operations and limitations of diagnostic testing equipment.
• general knowledge of the methods and processes for documenting and reporting diagnostic findings and recommendations.
• general knowledge of personal computer operation.

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 

• Interpret work order and locate and apply information.
• Apply safety requirements, including the isolation of equipment and use of personal protective equipment.
• Follow work instructions, operating procedures and inspection processes to:

• minimise the risk of injury to self and others
• prevent damage and wastage of goods, equipment and products
• maintain required production output and product quality.

• Modify a significant gas fuel system or sub-system including:

• selection, development and documenting of success factors and evaluation criteria before undertaking the modification
• selection, development and validation of the modification methodology, processes and specification
• application of modification specification, methodology and process
• the documenting and reporting of the outcomes.

• Work effectively with others.
• Modify activities to cater for variations in workplace context and environment.

Context of , and specific resources for assessment 

Assessment may occur on the job or in a workplace simulated facility with process equipment, materials, work instructions and deadlines.

Access to an operational gas fuel system requiring modification, testing equipment as stipulated in the Range Statement, technical information and a work environment.

Method of assessment 

Assessment of this unit of competence is most likely to be project related and require portfolios or other forms of indirect evidence of process. Direct evidence will 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 projects.

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 

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.

Gas fuel systems modifications 

Gas fuel systems modifications to be covered by this unit may include those to:

• enhance engine performance
• maintain emissions
• meet Australian Design Rules
• meet legislative requirements retrospectively.

Inputs to the modification method and processes 

Inputs to the modification method and processes may be obtained from customer requirements, manufacturer/ component supplier specifications, outcomes of diagnostic processes or from regulatory, licensing, intellectual property legislation, safety requirements and Australian Design Rules.

Unit context 

• WHS requirements include legislation, vehicle industry regulations, safety management systems, hazardous substances and dangerous goods code and safe operating procedures.
• Work is carried out in accordance with legislative obligations, Australian Design Rules, environmental legislation, health regulations, manual handling procedures and organisation insurance requirements.
• Work requires individuals to demonstrate research, analytical, judgement and problem-solving skills in the diagnosis of faults.

Evaluation criteria 

Evaluation criteria, sometimes referred to as success factors, are to be established prior to a modification being undertaken and are to cover safety, functionality, survivability, maintainability, life cycle cost and aesthetics.
