• workplace procedures required for removing, inspecting and fitting earthmoving and OTR tyres, including: documentation procedures; establishing serviceability of tools and equipment; housekeeping procedures, including: disposal of excess materials and scrap tyres, examination of tools and equipment, identification, tagging and isolation of faulty equipment, storage of equipment, tyres and wheel assemblies; hazard identification and risk control methods, including: ballast identification, types and application, crack testing for rim components, crushing or trapping, falling or dropped objects, inflation and deflation including pre- and post-checks, moving mobile plant, operating indoors, outdoors, underground, and at nighttime, overhead obstructions, projectiles, flying debris or components, rupturing wheel components, serviceability requirements relating to tyres, wheels and rims, suitability of the wheel or rim to the tyre, types and applications of tyre additives, tyre fill adding/removal methods, tyre fill identification, types and application, working on unstable ground
• removal procedures of earthmoving and OTR wheel and rim assemblies, including: pre-removal inspections; removal of wheel fasteners and retaining components; removal procedures for different wheel and rim assembly types, including: one-piece wheels and rims, rim- or hub-mounted split rims, multipiece lock rings assemblies, divided wheel assemblies; identification of wheel and rim components and matching criteria
• fitting and refitting procedures of earthmoving and OTR tyres, including: checking correct assembly; identifying compatible and serviceable components; OEM rim and component tolerance checks; methods for fitting multipiece and divided wheel assemblies; post-fitting inspection
• earthmoving and OTR vehicle tyres, wheels and rim assembly information including: types and classifications of earthmoving and OTR tyres, rims and wheel assemblies; types of retaining systems, tools and equipment for removing and fitting earthmoving and OTR wheel and rim assemblies; workplace tyre management systems, including: paper-based tyre management systems, digital tyre management systems; identifying tyre pressure monitoring systems (TPMS) in assemblies

Foundation skills

• Reading: reads and interprets: written information in workplace procedures, OEM instructions, and Work Health and Safety (WHS) requirements relating to removing, inspecting and fitting earthmoving and OTR tyres; charts, lists, drawings and other applicable documents.
• Writing: documents inspection findings and recommend repair and replacement actions; engages with workplace documents.
• Oral communication: asks questions to clarify inspection observations, instructions and procedures; reports inspection results; briefs team and customers
• Numeracy: reads and interprets metric and imperial systems of measurement; reads and interprets mathematical information, including charts and drawings; uses specialist tools and measuring equipment, including: gauges and pressure regulators; pressure testing tools.
• Digital literacy: uses workplace computerised technology and tools relating to the removal and refitting of earthmoving and OTR tyres.
• Planning and organising: plans and prioritises own work to achieve required outcomes; plans appropriate risk controls to minimise risks before, during and after the tyre fitting process.
• Self-management: selects and uses appropriate equipment, materials, processes and procedures; recognises own limitations when selecting and using tools and equipment and seek timely advice.
• Problem-solving: seeks information and assistance as required to solve problems; identifies tyre, wheel and rim assembly condition and performance; matches tyres to wheel and rim assemblies and vehicle type.
• Teamwork: works alongside other team members in a work environment, including those fulfilling other roles, such as riggers, dogmen, mechanics, tyre fitters, drivers and site operators.
