Elements and Performance Criteria

1. Prepare for filing and saw setting
   • Review work order and where required check with appropriate personnel.
   • Select appropriate repair, maintenance and personal protective equipment and check for operational effectiveness in line with manufacturer's recommendations.
   • Plan setting process in line with work order.
   • Follow organisational safety procedures thoughout all maintenance and repair processes.
   • Set up saw in selected jig to enable setting work.
   • Check kerf and finish requirements to suit machine horsepower, saw type and cutting conditions.
   • Examine individual teeth to check amount of setting required.
   • Maintain welding condition, saw temper and consistency of set between alternate teeth.
   • Measure and assess teeth for correct setting.
   • Bevel teeth and assess bevel length.
   • Apply set to teeth and allow for estimated spring back.
   • Check set to teeth using gauges in line with organisational procedures.
   • Identify routine processing and equipment faults and resolve or report to appropriate personnel.
