  • 3.2 Inspect any exposed steel and/or fabric cords
  • 3.3 Determine any remedial action required
  • 3.4 Prepare steel and/or fabric cords as required
  • 3.5 Review for hidden injuries
  • 3.6 Measure and record dimensions of injury as required
  • 3.7 Make any required decisions about the repair
  • 3.8 Strip liner and prepare inner surface, as required, using appropriate hazard controls
4 Complete repair preparation
  • 4.1 Shape, as required, and final-buff to standard
  • 4.2 Clean injury area ready for further process steps
  • 4.3 Complete any required paperwork
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance.
Tyre securing methods
Tyre securing methods may include, but are not limited to:
mounts and stands
chocks
wall or floor mounted frames, manually, electrically or hydraulically operated
Required tools
Required tools may include, but are not limited to:
rotary gouging and cutting equipment
knives and other blade cutting tools
surface preparation tools, such as contour and doughnut wheels
rotor saw
pin wheel
rotary and hand wire brushes
buffing and wire wheels
rotary stones
rotary rasps and other finishing tools
Foreign material
Foreign material that may contaminate the injury area or cause a health risk must be removed (e.g. spray paint used to mark tyres). This will include removing any rocks or other foreign material
Injuries to tyres
Injuries to tyres may include, but are not limited to:
cuts, abrasion, splits, cracks and crazing
separations within the structure
deformities both surface and internal
penetrations into and through the casing/carcass
Location of repairs
Repairs may be undertaken to the:
tread or crown, including steel components
shoulder
sidewall
bead area
liner
body cords
Injuries
Injuries may include, but are not limited to:
injuries which do not need repair and should be returned to the customer to be used as is
injuries which should be repaired
injuries which are beyond repair and so the tyre should be scrapped
Hidden injuries
Hidden injuries may include, but are not limited to:
cuts
oxidation
separations
Standards
Standards may include, but are not limited to:
AS 4457.2-2008 Earth-moving machinery - Off-the-road wheels, rims and tyres - Maintenance and repair - Tyres
Rubber Manufacturer’s Association of America (RMA)
Supplier standards, such as technical data sheets and manuals
internal organisational standards
Procedures
Procedures may be written, verbal, computer-based or in some other form. They may include, but are not limited to:
all work instructions
standard operating procedures
formulas/recipes
batch sheets
temporary instructions
any similar instructions provided for the smooth running of the plant
good operating practice as may be defined by industry codes of practice
Procedures would be expected to comply with any relevant government regulations.
Paperwork
Paperwork may be paper or electronic-based
Appropriate action
Appropriate action includes, but is not limited to:
determining problems needing action
accessing and applying relevant technical and plant data
applying appropriate problem solving techniques to determine possible fault causes
rectifying problem using appropriate solution within area of responsibility
following through items initiated until final resolution has occurred
reporting problems outside area of responsibility/ability to designated person
Health, safety and environment (HSE)
All operations to which this unit applies are subject to stringent HSE requirements, which may be imposed through state or federal legislation, and these must not be compromised at any time. Where there is an apparent conflict between Performance Criteria and HSE requirements, the HSE requirements take precedence.
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
Critical aspects for assessment and evidence are:
tyre injury is identified and appropriate action for preparation/inspection determined
consistent application of preparation, inspection and testing standards
safety procedures are always followed.
Context of and specific resources for assessment
Assessment will occur on an HOTR tyre repair facility. Resources required include suitable access to an operating plant or equipment that allows for appropriate and realistic simulation. A bank of case studies/scenarios and questions will also be required to the extent that they form part of the assessment method. Questioning may take place either in the workplace, or in an adjacent, quiet facility such as an office or lunchroom. No other special resources are required.
Method of assessment
Competence in this unit may be assessed:
by observation over a range of tyre preparation/inspection procedures undertaken in the workplace
in a situation allowing for the generation of evidence of the ability to respond to problems
by using a suitable simulation and/or a range of case studies/scenarios
through a combination of these techniques.
In all cases it is expected that appropriate practical/simulation assessment will be combined with targeted questioning to assess the required knowledge, and theoretical assessment will be combined with appropriate practical/simulation or similar assessment.
Guidance information for assessment
Assessment processes and techniques must be appropriate to the language, competency and safety requirements of the site and consistent with workplace systems or procedures.
