This unit applies to identifying and correcting weaving process problems in a textile operating environment. Discretion and judgement may be required, for both self and others, in planning and selecting processes, procedures or outcomes. Repairs are undertaken in accordance with established workplace procedures and practices and may include requirements recommended by manufacturers.

Work may be conducted in small to large scale enterprises and may involve individual and team activities.

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 problem solving to identify faults and problems of equipment used in textile production. This unit also requires the ability to communicate information on equipment operations and production requirements.

Prerequisites

ELEMENT

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 should be assessed in conjunction withLMTTX3003B Set up and operate weaving looms for production

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.
