Elements and Performance Criteria

1. Set up industrial sewing machine for production operation or product change
   • Production specifications and work orders are interpreted to determine optimum sewing machine settings for product and operator.
   • Documentation relating to machine settings, operation and maintenance is interpreted, referenced and applied according to the needs of the task and operator
   • Tools appropriate for the machine and task are selected, prepared and used in a safe and effective manner to set up machine for operation
   • Machine is set up according to required specifications for operation or product change including fixing of required attachments and to run at optimum quality and efficiency levels
   • Needle or needles are threaded, checked and tension set for planned sewing operations
   • Oil reservoir and lubrication system is checked prior to operation
   • Fabric feed system is checked prior to operation
   • Sewing machine operators are instructed of any special operating requirements
2. Test industrial sewing machine settings
   • Sewing machine is operated in accordance with manufacturer's and workplace instructions to test settings against specifications and operational standards
   • Sewn product or sample is examined to confirm desired sewing motion and stitch is achieved and to identify required adjustments to machine settings or production specifications
   • Quality tests are conducted or organised as required to ensure optimal production outcomes are achieved
   • Required adjustments are identified and documented and machine settings adjusted accordingly
3. Diagnose and fix sewing problems
   • Industrial sewing machine operation is monitored to assess operational efficiency and safe operation in accordance with OHS procedures
   • Discuss the nature and extent of sewing faults with operator
   • Sewn product is assessed to identify sewing faults
   • Problems and faults are identified and analysed to determine root cause
   • Fault diagnosis is established and strategy for repair is determined
   • Sewing machine is returned to optimal performance through readjustment of settings or repair or replacement of faulty machine parts
   • Sewing machine is tested and sample produced to ensure problems have been fixed
4. Communicate operational information
   • Records are maintained and reports prepared where necessary
   • Adjustments to machines are documented and discussed with appropriate personnel
   • Instructions to operators are given and documented

Range Statement

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the Performance Criteria, is detailed below. Add any essential operating conditions that may be present with training and assessment depending on the work situation, needs if the candidate, accessibility of the item, and local industry and regional contexts.
Legislative/regulatory requirements	All work must comply with relevant Federal and State or Territory legislative or regulatory requirements.
Industrial sewing machine may include	Industrial sewing machines include: lockstitch and chain stitch table mounted machines with power being from a motor mounted under the table and connected to the sewing machine by a pulley overlock table mounted sewing machines and sergers with power being from a motor mounted under the table and connected to the sewing machine by a pulley high volume automatic and manually operated hem, selvedge and embroidery sewing machines
Machine settings may include	gaps tolerances clearances tension needle speed and timing air cooling and lubrication system settings direction feed rate other settings depending on the industrial sewing machine settings depending on the machine model and function and production requirements
OHS procedures	OHS procedures must include hazard identification and control, risk assessment and implementation of risk reduction measures specific to the tasks described by this unit, and may include: manual handling techniques standard operating procedures personal protective equipment safe materials handling taking of rest breaks ergonomic arrangement of workplaces following marked walkways safe storage of equipment housekeeping reporting accidents and incidents other OHS practices relevant to the job and enterprise
Faults may include	contamination incorrect thread tension mechanical breakdown electrical or electronic fault poor feeding and threading of needle/s dirty or oily marks on thread or fabric incorrect stitch thread, lint or debris in rotary hook, bobbin case, needleplate and feed dog and the motor and oil reservoir puckering thread breakages uneven thread delivery including loop stitches and slip stitches poor lubrication and cooling resulting in needle overheating and fabric burn
Repairs include	Repairs may include the following depending on the nature of the fault and workplace practices in the enterprise: correcting threading faults tensioning removal and replacement of faulty or worn parts setting of clearances, limits and fits re-setting or re-programming of controls and sensors repair or replacement of pneumatic or hydraulic components Depending on the fault, particular repairs may require additional training in general engineering, fluid power and control systems.
