5 Perform planned maintenance activities

• 5.1WHS/OHS risk control measures and procedures for carrying out work are followed
• 5.2Maintenance schedule and process compliance requirements are confirmed and work is appropriately sequenced according to job specification
• 5.3Appropriate person/s is consulted to ensure work is coordinated effectively with others
• 5.4Resources needed to conduct maintenance are obtained according to organisational procedures and are checked against job requirements
• 5.5Tools, equipment and testing devices needed to conduct maintenance are obtained according to organisational procedures and checked for correct operation and safety
• 5.6Live and operating system is tested or measured strictly according to WHS/OHS requirements and within established safety procedures
• 5.7Electrical equipment is checked as being isolated, where necessary, strictly according to WHS/OHS requirements and within established safety procedures
• 5.8Electrical equipment to be maintained is inspected and evaluated for compliance with system specifications
• 5.9Non-compliant electrical equipment components are rectified or repaired according to system specifications

6 Perform breakdown maintenance

• 6.1Nature of breakdown is confirmed with appropriate personnel
• 6.2Extent of breakdown is evaluated and confirmed using diagnostic and troubleshooting techniques
• 6.3Restrictions are applied to operations, as necessary, and agreed to with the Master
• 6.4Electrical equipment is checked as being isolated, where necessary, strictly according to WHS/OHS requirements and within established safety procedures
• 6.5Repair work is carried out according to system specifications
• 6.6Master is notified of completion of repair work and details are documented

7 Monitor, adjust and report on implementation of maintenance plan

• 7.1Maintenance tasks are monitored to ensure they are completed according to maintenance plan and statutory survey requirements
• 7.2Electrical systems are monitored to ensure achievement of planned outcomes
• 7.3Costs are monitored and controlled
• 7.4Adjustments are made to maintenance plan to take into account failure to achieve planned outcomes
• 7.5Reports are completed according to maintenance plan requirements and organisational procedures
• 7.6Recommendations to improve maintenance plan safety, efficiency and effectiveness are implemented under regular review of SMS
• 7.7Maintenance tasks are monitored to ensure they are completed according to maintenance plan and statutory survey requirements

What does an assessment tool for MARB047 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for MARB047 needs to address all 70 unit components: 7 elements with 46 performance criteria, 12 performance evidence requirements, 12 knowledge evidence requirements, and the foundation skills. A coverage matrix mapping each question and task to these components is what an auditor looks for.

How does Auditori generate an assessment tool for MARB047?

Auditori pulls the current release of MARB047 from training.gov.au and generates a complete package: candidate assessment, assessor guide with model answers and observation criteria, and a coverage matrix mapping every component. A suitably qualified person then reviews and approves the draft in a built-in workflow — consistent with ASQA's guidance on AI use in VET — before export as branded PDF and editable Word.

Is the first assessment tool really free?

Yes. Every new account includes one free credit — enough to generate the complete assessment tool for MARB047 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing MARB047 assessment instead of generating a new one?

Yes — upload your existing assessment or learner guide and Auditori maps it against every element, performance criterion, PE and KE of MARB047, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
