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.
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.
