Elements and Performance Criteria

1. Undertake preventative maintenance checks/adjustments on hydraulic systems
   • System components, assemblies or sub-assemblies are identified and prepared for inspection/preventative maintenance.
   • Visual inspection and testing with appropriate test equipment are carried out according to fluid power principles, procedures and safety requirements.
   • Scheduled preventive maintenance tasks are performed including obvious repairs and adjustments according to manufacturers' specifications using fluid power techniques/practices.
2. Undertake fault finding on hydraulic systems
   • Designated hydraulic system components are identified and a visual inspection of the system is carried out for the collection of fault finding data.
   • System operator is consulted where appropriate and additional data is collected.
   • Maintenance reports and preventative maintenance schedules are checked and reviewed for additional fault finding data.
   • Using fluid power principles, checks and tests are undertaken using appropriate test equipment and techniques.
   • Faults and malfunctions are identified and verified.
   • Faults and malfunctions are documented or reported by appropriate means to designated personnel and actioned.
3. Repair and/or rectify hydraulic system
   • System or sub-assembly is isolated safely and residue pressure is discharged in accordance with prescribed procedure and checked for correct isolation.
   • Isolated system or sub-assembly is tagged according to designated means.
   • Components or sub-assembly is removed from system using correct removal principles and techniques.
   • Components or sub-assemblies are dismantled, examined and verified for replacement, overhaul or repair, using correct and appropriate techniques and procedures.
   • Replacement items are selected from manufacturers' catalogues to meet specifications.
   • Faulty items are rectified using correct and appropriate principles, techniques and procedures.
   • Component or sub-assembly items are refitted to equipment and tested for correct operation against specifications.
4. Recommission hydraulic system
   • System or sub-assembly is recommissioned according to prescribed procedures and specifications.
   • Using fluid power principles and system applications techniques, correct operation of the system is verified.
   • Appropriate follow-up procedures are instigated.
   • Maintenance records/service reports are updated and completed by appropriate designated means.

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 maintain hydraulic systems Competency in this unit cannot be claimed until all prerequisites have been satisfied
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 on and off the job Where assessment occurs off the job that is the candidate is not in productive work then an appropriate simulation must be used where the range of conditions reflects realistic workplace situations The competencies covered by this unit 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 maintaining and repairing hydraulic systems 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 techniques 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.
Preventative maintenance	Preventative maintenance is undertaken on a periodic basis and appropriate documentation is maintained
Systems	For the purposes of this unit a system is regarded as a functionally related group of elements. The unit extends to tests involving interacting, interrelated, or interdependent components
Test equipment	Leak testers, escape rate gauges, hand held pressure testers and other appropriate equipment
Rectify	Replacement, repair and/or reuse of components
