EVIDENCE GUIDE 

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment 

Critical aspects for assessment and evidence required to demonstrate competency in this unit 

The evidence required to demonstrate competency in this unit must be relevant to workplace operations and satisfy holistically all of the requirements of the performance criteria and required skills and knowledge and include achievement of the following:

• diagnose faults and repair requirements
• dismantle and reassemble parts and components of machinery and equipment
• select and use tools and materials appropriate to the task
• carry out repairs and servicing of a range of machinery and equipment
• determine appropriate cutting and welding techniques
• operate welding equipment safely and effectively.

Context of and specific resources for assessment 

Competency requires the application of work practices under work conditions. Selection and use of resources for some worksites may differ due to the regional or enterprise circumstances.

RANGE STATEMENT 

The range statement relates to the unit of competency as a whole.

Machinery and equipment may include:

• harvesters
• tractors
• seeding machines with components such as metering systems, air flow control, blower drives, air system, electronic monitoring systems, hydraulic hoses and couplings
• engines
• boom spray units
• harvesters
• associated grain-handling equipment.

The repair and replacement process for machinery may involve:

• rectifying major faults and restoring machinery and equipment systems to an acceptable status of operation by replacing worn, failed, faulty or damaged mechanical, hydraulic, basic electrical or frame and support structure parts and components.

The repair and replacement process for machinery may include:

• carrying out tests and making adjustments
• rectifying faults by welding, aligning, tightening, securing or adjusting components that are not a part of normal service operations
• Major repairs may require dismantling and assembly operations.
