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.
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the range of conditions. |
1. Prepare for repair | 1.1 Review work order and where required check with appropriate personnel. 1.2 Select appropriate repair, maintenance and personal protective equipment and check for operational effectiveness in line with manufacturer's recommendations. 1.3 Plan levelling and tensioning process in line with work order. |
2. Assess saw condition | 2.1 Follow organisational safety procedures thoughout all maintenance and repair processes. 2.2 Handle saws to avoid damaging teeth. 2.3 Clean foreign material on saw surfaces for inspection. 2.4 Inspect saw to assess condition of teeth and saw plate. 2.5 Declare saw unserviceable where hazardous defects are found. 2.6 Segregate and dispose of unserviceable saws in line with organisational procedures and environmental protection practices. |
3. Level saw blades | 3.1 Assess and match radial and circular ridges or lumps on both sides of blade. 3.2 Use gauges and straight edges in radial and circular directions and monitor for accuracy. 3.3 Remove ridges or lumps progressively through levelling and use stretcher or levelling rolls to flatten. 3.4 Control hammering and rolling patterns to reduce internal blade stresses and avoid spring back and re-occurring defects. |
4. Tension saw blades | 4.1 Assess consistency of required blade curvature with straight edge or tension gauge. 4.2 Tension and check blade to ensure tension amount, distribution, placement and level are in line with manufacturer’s recommendations. 4.3 Complete repairs to damaged saw blades and dispose of irreparable saw blades line with and environmental protection practices. 4.4 Identify routine processing and equipment faults and resolve or report to appropriate personnel. |
