Elements and Performance Criteria

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.

The Evidence Guide provides advice on assessment and must be read in conjunction with the Performance Criteria, Required Skills and Knowledge, the Range Statement and the Assessment Guidelines for the Training Package.

Critical aspects of evidence to be considered
Demonstrates skills and knowledge to:
interpret production specifications accurately
set and operate industrial sewing machine safely and correctly
perform sample runs and analyse results
identify and make appropriate re-adjustments
determine root cause of operational problems
solve operational problems
apply workplace health and safety policies in production operations
maintain accurate records

Consistency in performance
Consistently applies skills and knowledge when:
organising work
completing tasks
identifying improvements
using workplace practices
using OHS practices
recording and reporting accidents and incidents
assessing operational readiness of equipment used and work processes
recognising and adapting to cultural differences in the workplace, including modes of behaviour and interactions
completing work systematically with attention to detail without damage to goods and equipment

Resource implications
Access is required to real or appropriately simulated situations, including work areas, materials and equipment, and to information on workplace practices and OHS practices.

Context for assessment
Assessment may occur on the job or in an appropriately simulated environment.

Interdependent Assessment
This unit may be assessed independently or in combination with other relevant units.
