Description
This unit of competency covers the skills and knowledge needed to cure repairs to tyres defined by AS 4457.2-2008 Earth-moving machinery - Off-the-road wheels, rims and tyres - Maintenance and repair - Tyres (or its authorised replacement) or similar tyres.
Notes
Elements and Performance Criteria
1 Prepare for job
  • 1.1 Select required curing equipment
  • 1.2 Move tyre into suitable position for curing
  • 1.3 Secure tyre ready for curing
  • 1.4 Determine cure conditions required from injury dimensions, rubber compounds and equipment selected
  • 1.5 Select curing equipment components to suit repairs to be cured
  • 1.6 Check and wear required personal protective equipment (PPE)
2 Set up pressure curing system to procedures
  • 2.1 Place and secure packing
  • 2.2 Position curing system components and secure
  • 2.3 Apply pressure appropriate to the system being used
  • 2.4 Check curing system is ready for the curing process
3 Cure repair to procedures
  • 3.1 Set temperature required for curing
  • 3.2 Monitor heat and pressure over the whole curing cycle and make adjustments if required
4 Complete repair
  • 4.1 Check heat and pressure cure cycle has completed
  • 4.2 Remove curing system
  • 4.3 Remove packing and any other ancillary materials used
  • 4.4 Inspect repair to ensure that it meets the standard
  • 4.5 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
Location of repairs
Repairs may be undertaken to the:
tread or crown, including steel components
shoulder
sidewall
bead area
liner
body cords
Curing equipment components
Curing equipment components may include, but are not limited to:
heat pads
size and shape of air bags (for a Monarch system)
contours (for a Thermopress system)
hydraulic equipment operation
pneumatic equipment operation
compressor operation
Packing
Packing includes, but is not limited to:
tread voids
flow blocks
vent supports
Tread voids are the space between the lugs on the tread. Packing is typically done on voids adjacent to a repair.
Cure cycle
Ensure that the repair has completed its required cure cycle and ensure that the temperature has been reduced to the manufacturer’s recommendations, then release pressure.
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/repair is identified and appropriate action for curing determined
consistent application of curing 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 curing 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.
