Notes
Elements and Performance Criteria
1. Prepare for maintenance
  • 1.1. Applicable Occupational Health and Safety (OHS), environmental, legislative and organisational requirements relevant to maintaining wide band saw blades are identified and followed
  • 1.2. Work order is reviewed and checked with appropriate personnel
  • 1.3. Wide band and gang saws to be maintained are removed from the designated machinery
  • 1.4. Equipment is selected appropriate to work requirements and checked for operational effectiveness in line with manufacturer's recommendations
  • 1.5. Maintenance process is planned in line with site procedures and environmental requirements
  • 1.6. 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 blade surfaces is cleaned for inspection
  • 2.3. Saw is inspected to assess condition of teeth and saw blade
  • 2.4. Teeth and tips requiring repair or replacement are checked and marked
  • 2.5. Saw is declared unserviceable where hazardous defects are found and disposed of in line with site procedures, manufacturer's recommendations and environmental requirements
3. Level, tension and back-gauge saw blade
  • 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 levelling and the use of stretcher rolls or levelling rolls to achieve flatness
  • 3.4. Levelling or rolling patterns are controlled to localise stresses to avoid spring-back and re-occurrence of defects
  • 3.5. Saw blade is checked against required curvature using a gauge to identify tensioning requirements
  • 3.6. Tension curvature is obtained across and along saw blade in line with required standard
  • 3.7. Alignment of saw back is checked against saw tolerances using a gauge and areas not conforming are rolled to obtain required tolerance
4. Repair teeth and blade cracks
  • 4.1. Saw blade is placed in welding jig for applying heat and undertaking welding activities
  • 4.2. Weld line is marked to check amount of damaged tooth to be removed or crack to be repaired 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 free 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 or cracked area is 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 blade
  • 4.7. Teeth or cracks are ground or filed to required shape, tolerance and pitch
  • 4.8. Saws where teeth, tips or blade cracks are damaged during the repair process and cannot be repaired are disposed of in line with site procedures, manufacturer's recommendations and environmental requirements
  • 4.9. Repair process and equipment faults are investigated, recorded and reported in line with site requirements

Curvature
is the distance or chord height measured when the centre of the blade falls away as a result of an elongating inner zone
chord height 'tension drop' is generally measured with a tension gauge having a curvature that suits blade width, thickness, and production conditions
Tensioning
is the process of using mechanically driven rolls to compress and elongate certain sections of the inner zone of a blade; compression of the inner zone places the outer edges of the blade in tension
artificially stiffens the cutting edge and reduces the influence of sawing forces that cause buckling of the cutting edge and lateral instability

Overview of assessment
A person who demonstrates competency in this unit must be able to provide evidence that they can safely and efficiently maintain wide band saw blades and gang 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 maintaining wide band saw blades
following organisational policies and procedures relevant to maintaining wide band saw blades
maintaining wide band and gang saw blades in line with work order and within prescribed organisational requirements
removing and replacing saws from equipment
assessing 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 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
