This unit applies to the setting up of spinning machines for production and the maintenance, repair, adjustment and testing of machines to ensure efficient working order. Discretion and judgement may be required, for both self and others, in planning and selecting processes, procedures or outcomes.

This unit does not cover all repair and adjustment functions associated with spinning machines. In particular skills associated with general engineering (fitting), electrical and electronic systems , and fluid power systems may be required according to the nature of the set up, repair or adjustment, and the workplace practices of a particular enterprise.

Work may be conducted in a variety of environments, such as operational workplace activities, restricted space, hazardous, controlled or exposed conditions.

The application of this unit is according to OHS practices of the enterprise and workplace practices, which may include:

requirements prescribed by legislation, awards, agreements and conditions of employment

standard operating procedures

work instructions

oral, written and visual communication

quality practices, including responsibility for maintenance of own work quality and contribution to quality improvement of team or section output

housekeeping

tasks related to environmental protection, waste disposal, pollution control and recycling

This unit requires the application of skills associated with planning and organising of resources and machinery for the required work, as well as applying skills and knowledge of machines and equipment to ensure production outcomes are met. Initiative and enterprise, and problem solving are key skills required to ensure operational efficiency of machines. This unit also requires and ability to communicate in writing and verbally with others.
