Elements and Performance Criteria

1. Identify pneumatic/hydraulic system problems
   • Categorise the types of equipment malfunctions due to fluid power problems
   • Identify the effects on product quality of fluid power problems
   • Describe the function of components on the fluid power circuit diagram
   • Identify possible faulty components from a circuit diagram
   • Identify hazards arising from the problem and implement appropriate hazard control

Range Statement

This field allows for different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included.
Regulatory framework	The latest version of all legislation, regulations, industry codes of practice and Australian/international standards, or the version specified by the local regulatory authority, must be used, and include one or more of the following: legislative requirements, including work health and safety (WHS) industry codes of practice and guidelines environmental regulations and guidelines Australian and other standards licence and certification requirements
Procedures	All operations must be performed in accordance with relevant procedures. Procedures are written, verbal, visual, computer-based or in some other form, and include one or more of the following: work instructions standard operating procedures (SOPs) safe work method statements (SWMS) formulas/recipes batch sheets temporary instructions any similar instructions provided for the smooth running of the plant
Equipment using fluid power control systems	Equipment that uses fluid power control systems include one or more of the following: pumps pressure controls directional control valves (DCVs) remote operated valves (ROVs) flow control actuators accumulators filters heat exchangers proportional, servo and cartridge valves
Non-routine problems	Non-routine problems must be resolved by applying operational knowledge to develop new solutions, either individually or in collaboration with relevant experts to: determine problems needing action determine possible fault causes develop solutions to problems which do not have a known solution follow through items initiated until final resolution has occurred report problems outside area of responsibility to designated person Operational knowledge includes one or more of the following: procedures training technical information, such as journals and engineering specifications remembered experience relevant knowledge obtained from appropriate people
Hazards	Hazards include one or more of the following: high pressures (hydraulic and pneumatic) hot surfaces equipment failures heat, smoke, dust or other atmospheric hazards flammability and explosivity equipment or product mass slippery surfaces, spills or leaks noise, rotational equipment or vibration electricity other hazards that might arise
