Elements and Performance Criteria

1. Determine system requirements
   • Instructions regarding system requirements are obtained, understood and clarified as necessary.
   • Circuit drawings using standard symbols are interpreted correctly.
2. Select components for simple hydraulic circuits
   • Suitable fluids are selected for given hydraulic systems from specification charts and in accordance with safety procedures involving fluids.
   • Linear actuators and motors are selected to suit system requirements.
   • Control valves are selected to suit system requirements.
3. Verify component selection
   • Circuits are set up and operated on laboratory benches.
   • Operation is analysed and outcomes are verified against system requirements.

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	A person who demonstrates competency in this unit must be able to set up basic hydraulic circuits and verify outcomes
Critical aspects for assessment and evidence required to demonstrate competency in this unit	Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the criteria including required knowledge and be capable of applying the competency in new and different situations and contexts
Context of and specific resources for assessment	This unit may be assessed on the job off the job or a combination of both Where assessment occurs off the job ie the candidate is not in productive work an appropriate simulation must be used where the range of conditions reflects realistic workplace situations The competencies covered would be demonstrated by an individual working alone or as part of a team The assessment environment should not disadvantage the candidate This unit could be assessed in conjunction with any other units addressing the safety quality communication materials handling recording and reporting associated with setting up basic hydraulic circuits or other units requiring the exercise of the skills and knowledge covered by this unit
Method of assessment	Assessors should gather a range of evidence that is valid sufficient current and authentic Evidence can be gathered through a variety of ways including direct observation supervisors reports project work samples and questioning Questioning should not require language literacy and numeracy skills beyond those required in this unit of competency The candidate must have access to all tools equipment materials and documentation required The candidate must be permitted to refer to any relevant workplace procedures product and manufacturing specifications codes standards manuals and reference materials

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.
Simple hydraulic circuits	Limited to linear actuators, motors, control valves
Safety procedures	Selecting a suitable fire resistant fluid for a system, given its operating conditions; following required precautions when changing a system from one fluid to another
