Application
This unit of competency describes the outcomes required to plan and set up the assembly of timber floor trusses using a purpose built jig or computer-operated truss table and to oversee the operation of the truss press.
The unit applies to machine operators and product technicians in a timber and wood products production environment at either a truss/frame fabrication facility or timber merchant’s facility.
No licensing, legislative, regulatory, or certification requirements apply to this unit at the time of publication.
Elements and Performance Criteria
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. |
