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 replacement | 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 replacement process in line with work order. |
2. Remove worn tips | 2.1 Follow organisational safety procedures thoughout all maintenance and repair processes. 2.2 Clean foreign matter from saw and check for defects. 2.3 Identify and mark broken tips. 2.4 Remove broken tips minimising damage to the tooth seat and dispose of in line with environmental protection practices. 2.5 Repair tooth seats to specified tolerance and dimensions. |
3. Replace tips | 3.1 Set up saw in brazing jig in line with manufacturer's instructions. 3.2 Select brazing material and suitable technique for application and heat control. 3.3 Select appropriate replacement tip and braze into position. 3.4 Trial weld one tip and adjust to confirm weld pressure, current temperature and annealing settings against specifications. 3.5 Segregate and dispose of tips with sub-standard welds in line with environmental protection practices. 3.6 Set manual or automatic feeds in line with number of tips to be welded. 3.7 Complete tip replacement regularly; check and adjust annealing process temperatures to keep within specified range. 3.8 Remove surplus brazing material from saw surfaces and dress tip faces for sharpening. 3.9 Identify routine processing and equipment faults and resolve or report to appropriate personnel. |
