Application
The unit involves levelling and tensioning circular saws in a forest products factory setting The skills and knowledge required for competent workplace performance are to be used within the scope of the person's job and authority |
Elements and Performance Criteria
ELEMENT | PERFORMANCE CRITERIA |
1. Prepare for repair | 1.1. Applicable Occupational Health and Safety (OHS), environmental, legislative and organisational requirements relevant to levelling and tensioning circular saws are identified and followed 1.2. Work order is reviewed and checked with appropriate personnel 1.3. Equipment is selected appropriate to work requirements and checked for operational effectiveness in line with manufacturer's recommendations 1.4. Levelling and tensioning process is planned in line with site procedures and environmental requirements 1.5. Communication with others is established and maintained in line with OHS requirements |
2. Assess saw condition | 2.1. Saws are handled safely without damage to teeth 2.2. Foreign material built up on saw surfaces is cleaned for inspection 2.3. Saw is inspected to assess condition of teeth and saw plate 2.4. Saw is declared unserviceable where hazardous defects are found 2.5. Unserviceable saws are segregated and disposed of in line with site procedures, manufacturer's requirements and environmental requirements |
3. Level saw | 3.1. Radial and circular ridges or lumps are assessed and matched on both sides of the blade 3.2. Gauges and straight edges are used in both radial and circular directions and monitored for accuracy 3.3. Ridges or lumps are progressively removed through levelling, the use of structure rolls or levelling rolls to achieve flatness 3.4. Hammering and rolling patterns are controlled to reduce internal blade stresses to avoid spring-back and re-occurrence of defects |
4. Tension saw | 4.1. Consistency of blade curvature is assessed with a straight edge or tension gauge 4.2. Tension requirements are determined from assessment of curvature consistency and curvature required for site production requirements 4.3. Blade is tensioned using appropriate tools and equipment in line with required standard 4.4. Final checks are made to ensure tension amount, distribution, placement and level in line with site production requirements 4.5. Saws damaged in the levelling and tensioning process are repaired/sent for repair and those that cannot be repaired are disposed of in line with site procedures, manufacturer's recommendations and environmental requirements 4.6. Levelling and tensioning 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 level and tension circular saws 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 levelling and tensioning circular saws following organisational policies and procedures relevant to levelling and tensioning circular saws levelling and tensioning circular saws in line with work order and within prescribed organisational requirements removing and replacing circular saws from equipment assessing circular saw conditions 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 essential underpinning 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 underpinning knowledge Assessment must be by direct observation of tasks, with questioning on underpinning 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 essential underpinning 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 |
Range Statement
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included. | |
OHS requirements: | are to be in line with applicable Commonwealth, State or Territory legislation and regulations, and organisational safety policies and procedures, and may include: personal protective equipment and clothing safety equipment first aid equipment fire fighting equipment hazard and risk control fatigue management elimination of hazardous materials and substances safe forest practices including required actions relating to forest fire manual handling including shifting, lifting and carrying machine isolation and guarding |

Levelling | is the process of removing lumps and ridges in the blade using the appropriate and specialised saw hammers |

Equipment may include: | hammers stretcher rolls specialised levelling rolls tensioning instruments gauges and straight edges to check accuracy of hammering or rolling processes on particular sections of the saw blade |
Communication may include: | verbal and non-verbal language constructive feedback active listening questioning to clarify and confirm understanding use of positive, confident and cooperative language use of language and concepts appropriate to individual social and cultural differences control of tone of voice body language |
Disposing of may include: | recycling unserviceable saws/saws damaged in the levelling and tensioning process that cannot be repaired re-using unserviceable saws/saws damaged in the levelling and tensioning process that cannot be repaired |
Radial and circular ridges or lumps are to include: | defects obtained during saw operation |
Gauges and straight edges are to include: | measuring instruments used to check the results of hammering and/or rolling the blade |
Stretcher and levelling rolls are to include: | devices for assisting in the process of removing saw defects such as ridges and lumps |
Patterns | are the sequences applied when hammering or rolling identified areas of the blade to remove distortions and stresses in the form of lumps, ridges, twists, loose, tight, or neutral sections |
Spring-back | is the principle of compensating for 'metal creep' that causes saw blade steel to stress-relieve over time thus reducing tension permanence in blades |
Curvature | is the amount of tension achieved in a blade by compressing and elongating predetermined sections or zones in the blade |
