Issue Date: April 2024


Qualification -
Unit of Competency PMBPROD337A - Prepare heavy off-the-road tyres for repair
Description This unit of competency covers the skills and knowledge needed to prepare 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 for repair.
Employability Skills This unit contains employability skills.
Learning Outcomes and Application This competency is typically performed by operators applying knowledge of materials, knowledge and basic understanding of the tyre design, product purpose and processes to the preparation of tyres for repair. They will also validate the decision to repair the tyre once the injury has been exposed. It also requires the use of some discretion and judgment to recognise and resolve a range of problems.This unit should be interpreted in line with AS 4457.2-2008 Earth-moving machinery - Off-the-road wheels, rims and tyres - Maintenance and repair – Tyres.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.
Prerequisites/co-requisites Not applicable.

Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

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.

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

Required skills

Required skills include:

using skiving, rotary cutting and buffing tools

taking measurements

using required inspection equipment

communicating effectively

working safely in accordance with operational requirements and safe systems of work

reading and interpreting typical product specifications, job sheets and material labels as provided to operators

writing to the level of completing workplace forms and production reports

Required knowledge

Required knowledge includes:

organisational procedures

heavy off-the-road (HOTR) tyre construction

methods of identifying injury position, lug/position identification

tyre injury repair preparation methods

hazards and hazard controls associated with HOTR tyre repair preparation

reporting procedures

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

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.

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
