Assessment

Assessment tasks will be designed to reinforce and extend knowledge and skill competence within set and controlled parameters in accordance with each unit's learning outcomes and performance criteria requirements, including the setting of work based practical application tasks designed to provide evidence of competence outcomes, within periodic and scheduled timelines. Students will be expected to demonstrate the following required skills: - following work instructions, standard operating procedures (SOPs) and safe work practices; - obtaining and interpreting maintenance reports and preventative maintenance schedules; - inspecting and testing hydraulic system components, assemblies or sub-assemblies and carrying out preventative; - maintenance tasks to predetermined specifications using fluid power principles, tools and equipment; - consulting with system operator and carrying out visual inspection of hydraulic system and components with respect to the fault being investigated and other anomalies; - undertaking fault-finding and verifying and confirming faults/malfunctions; - checking component parts visually and dimensionally for compliance to specification and, where appropriate, marking faulty parts for repair, replacement or adjustment; - isolating and depressurising system or sub-assembly, confirming and using appropriate tagging system according to SOPs; - removing, dismantling and repairing/overhauling faulty system components or sub-assembly, including selecting replacement parts from manufacturers'/suppliers' catalogues, to site or manufacturers' specifications; - assembling hydraulic components or sub-assembly for compliance to specifications, refitting items to equipment and testing for correct operation; - recommissioning hydraulic system/sub-assembly to specifications and verifying correct operation and initiating any follow-up procedures, and; - updating and completing maintenance records and/or service reports.Students will also be expected to demonstrate the following knowledge: - safe work practices and procedures and use of personal protective equipment (PPE); - hydraulic principles; - manufacturers' specifications and structure of common hydraulic system components and their constituent parts; - hydraulic system/component faults that can be determined by visual inspection; - application of common hydraulic system/component test equipment; - scheduled preventative maintenance tasks; - common hydraulic system and component faults and any previous faults; - any previous maintenance carried out on the hydraulic system/components; - typical checks/tests that can be carried out on hydraulic systems/components and their application; - hydraulic system/component tests and testing techniques; - apparent faults/malfunctions; - documentation/reporting requirements with respect to verified faults/malfunctions; - procedures for initiating repair and/or overhaul of the hydraulic system; - procedures for isolating and depressurising hydraulic systems; - tagging requirements for isolated systems; - appropriate repair/overhaul procedures of hydraulic components; - hydraulic system operational specifications and system recommissioning procedures; - any appropriate follow-up maintenance or operational checks, and; - maintenance recording/reporting requirements and consequences of inaccurate or incomplete recording/reporting of maintenance/service activities.
