Elements and Performance Criteria
ELEMENT | PERFORMANCE CRITERIA |
1. Prepare for maintenance 2. Assess saw condition | 2.1. Applicable Occupational Health and Safety (OHS), environmental, legislative and organisational requirements relevant to maintaining frame saw blades are identified and followed 2.2. Work order is reviewed and checked with appropriate personnel 2.3. Frame saw blades to be maintained are removed from the designated machinery 2.4. Equipment is selected appropriate to work requirements and checked for operational effectiveness in line with manufacturer's recommendations 2.5. Repair process is planned in line with site procedures and environmental requirements 2.6. Communication with others is established and maintained in line with OHS requirements |
2.7. Saws are handled safely without damage to teeth 2.8. Foreign material built up on saw surfaces is cleaned for inspection 2.9. Saw is inspected to assess condition of teeth and saw blade 2.10. Teeth and tips requiring repair or replacement are checked and marked 2.11. Saw is declared unserviceable where hazardous defects are found and disposed of in line with site procedures, manufacturer's recommendations and environmental requirements | |
3. Hammer, tension and back-gauge saw | 3.1. Ridges or lumps across and along saw are assessed and matched on both sides of the blade 3.2. Gauges and straight edges are used in both directions and monitored for accuracy 3.3. Ridges or lumps are progressively removed through hammering and the use of structure rolls or levelling rolls to achieve flatness 3.4. Hammering or rolling patterns are controlled to localise stresses to avoid spring-back and re-occurrence of defects 3.5. Saw is checked against required curvature using a gauge to identify tensioning requirements 3.6. Tension curvature is obtained across and along saw in line with required standard 3.7. Alignment of saw back is checked against saw tolerances using a gauge and areas not conforming rolled to obtain required tolerance |
4. Repair teeth | 4.1. Saw is placed in welding jig for applying heat and undertaking welding activities 4.2. Weld line is marked to identify amount of damaged tooth to be removed and selected to minimise stresses 4.3. Metal is removed to the proposed line, the metal edge is prepared for the welding process and cleaned of burn marks 4.4. Worn, broken or ground surface is prepared for metal build up or replacement by applying heat and pressure 4.5. Teeth are built up or replaced using compatible welding material and welding procedures that ensure specified metal penetration and density 4.6. Weld run-off tabs are used to limit stress and hollows at edges of the saw 4.7. Teeth are ground or filed to required shape, tolerance and pitch 4.8. Metal is heat treated to temper recommended by manufacturer 4.9. Saws damaged during the repair that cannot be repaired are disposed of in line with site procedures, manufacturer's recommendations and environmental requirements 4.10. Repair process and equipment faults are investigated, recorded and reported in line with site requirements |

Evidence Required
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 | A person who demonstrates competency in this unit must be able to provide evidence that they can safely and efficiently maintain frame saw blades within organisational requirements |
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, and satisfy, all of the requirements of the elements of this unit and include demonstration of: following applicable Commonwealth, State or Territory legislative and regulatory requirements and codes of practice relevant to maintaining frame saw blades following organisational policies and procedures relevant maintaining frame saw blades maintaining frame saw blades in line with work order and within prescribed organisational requirements removing and replacing saws from equipment assessing saw condition in line with standard operating procedures |
Context of and specific resources for assessment | Competency is to be assessed in the workplace or realistically simulated workplace Assessment is to occur under standard and authorised work practices, safety requirements and environmental constraints Assessment of required knowledge, other than confirmatory questions, will usually be conducted in an off-site context Assessment is to follow relevant regulatory or Australian Standards requirements The following resources should be made available: workplace location or simulated workplace materials and equipment relevant to undertaking work applicable to this unit specifications and work instructions |
Method of assessment | Assessment must satisfy the endorsed Assessment Guidelines of the FPI11 Training Package Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with application of required knowledge Assessment must be by direct observation of tasks, with questioning on required knowledge and it must also reinforce the integration of employability skills Assessment methods must confirm the ability to access and correctly interpret and apply the required knowledge Assessment may be applied under project-related conditions (real or simulated) and require evidence of process Assessment must confirm a reasonable inference that competency is able not only to be satisfied under the particular circumstance, but is able to be transferred to other circumstances Assessment may be in conjunction with assessment of other units of competency The assessment environment should not disadvantage the candidate Assessment practices should take into account any relevant language or cultural issues related to Aboriginality, gender or language backgrounds other than English Where the participant has a disability, reasonable adjustment may be applied during assessment Language and literacy demands of the assessment task should not be higher than those of the work role |
