Application
This unit of competency covers the skills and knowledge required to identify and deal with routine mechanical and low voltage electronic faults in textile machinery. It includes repair or replacement of the faulty component or referral to other personnel.
The unit of competency applies to identifying and correcting mechanical faults and rectifying low voltage electrical problems in textile manufacturing machinery.
It does not include 240 Volt or higher equipment and circuits or higher level engineering skills. Work covered by engineering requirements and restricted electrical licences will require additional training to meet licence requirements.
Discretion and judgement may be required, for both self and others, in planning and selecting processes, procedures or outcomes.
Work may be conducted in a variety of environments including operational workplace activities, restricted space, hazardous, controlled or exposed conditions and day or night conditions.
No licensing, legislative or certification requirements apply to this unit at the time of publication.
