Range Statement

This section specifies 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. Bold italicised wording, if used in the performance criteria, is detailed below.

Safety and environmental requirements must include:

work health and safety (WHS) and occupational health and safety (OHS) requirements, including procedures for working with:

fluids under pressure

stored pressure hazards

hot fluid hazards

environmental requirements, including procedures for trapping, storing and disposing of fluids released from hydraulic systems.

Analytical and evaluative methodology must include:

diagnostic process, sequence, tests and testing equipment.

Tests must include:

stroke times for tilt and trim operation

leak down and creep

full load water testing.
