Description
This unit of competency describes the skills and knowledge required to level, tension, back gauge, weld and replace teeth on wide band saw blades that are over 70mm in width.The unit applies to individuals who maintain wide band saw blades in a forest and forest product factory setting.All work must be carried out to comply with workplace procedures, according to state/territory health and safety regulations, legislation and standards that apply to the workplace.No licensing, legislative or certification requirements apply to this unit at the time of publication.
Notes
Elements and Performance Criteria
1. Prepare for maintenance
  • 1.1 Review work order to determine job requirements and, where required, seek clarification from appropriate personnel
  • 1.2 Review environmental protection procedures and workplace health and safety requirements, including the use of personal protective equipment, equipment lock-out and safe manual handling techniques
  • 1.3 Identify, assess and take actions to mitigate risks and hazards associated with maintaining wide band saw blades
  • 1.4 Identify and implement workplace procedures for minimising waste material and maximising energy efficiency
  • 1.5 Select appropriate tools and equipment, and check for operational effectiveness according to manufacturer recommendations
  • 1.6 Plan maintenance process according to work order and workplace requirements
2. Assess saw blade condition
  • 2.1 Remove wide band saw blade from machinery
  • 2.2 Handle saw blade to avoid damaging teeth
  • 2.3 Clean foreign material from blade surfaces
  • 2.4 Inspect saw blade to assess the condition of teeth, tips and saw blade
  • 2.5 Check and mark teeth or tips requiring repair or replacement
  • 2.6 Declare saw blades unserviceable where hazardous defects are found,or blade has become too narrow for use
  • 2.7 Segregate and dispose of unserviceable saw blades according to workplace procedures and environmental protection practices
3. Level, tension and back gauge saw blade
  • 3.1 Use a straight edge to identify lumps and ridges across and along saw blade on both sides of the blade
  • 3.2 Remove ridges or lumps progressively by levelling the saw blade with hammers, levelling attachments or stretcher rolls
  • 3.3 Control rolling patterns to induce the correct amount of tension into the saw blade
  • 3.4 Use a tension gauge of appropriate curvature to verify the saw blade has sufficient tension, and tension is correctly positioned across the blade and is evenly distributed along the length of the blade
  • 3.5 Use an accurate back-gauge to check back length, and roll nonconforming areas to adjust back length to workplace tolerance
4. Repair teeth and blade cracks
  • 4.1 Place saw blade in welding jig for heat application and welding activities
  • 4.2 Check amount of damaged tooth to be removed or crack to be repaired and mark weld line
  • 4.3 Remove metal to proposed line, prepare the edge for welding and clean burn marks
  • 4.4 Apply heat and pressure to prepare worn, broken or ground surface for metal build-up or replacement
  • 4.5 Build up or replace teeth or cracked area using material and processes that ensure specified metal penetration and density
  • 4.6 Use weld run-off tabs to limit stress and hollows at edges of the saw blade
  • 4.7 Grind or file teeth or cracks to required shape, tolerance and pitch
  • 4.8 Dispose of saws with irreparable teeth, tips or blades according to workplace procedures and environmental protection practices
  • 4.9 Identify routine processing and equipment faults, and resolve or report to appropriate personnel
