Elements and Performance Criteria

1. Prepare for cleaning
   • Machinery is safely switched off before cleaning is started
   • The cleaning equipment and materials most suitable for the machine are selected
2. Commence cleaning
   • Vacuum systems are checked for wear, opened and cleaned with compressed air and suctions replaced if necessary
   • Rollers and drums are checked for wear and cleaned
   • Jaws and grippers are cleaned and checked for wear
   • Glue units are checked for wear and cleaned and excess glue and build-up removed from glue nipples
   • Glue applicators are cleaned and checked for wear
   • Hot melt residues are removed and glue pot is cleaned
   • Base and underneath of machine is cleaned of print ink and glue residue
   • Entire machine is blown down top to bottom and all grease and oil is removed from components, housings and the floor
   • Cleaning methods which are safe, avoid harm to the environment and which follow the manufacturer's instructions are used
3. Complete cleaning
   • Used cleaning agents and waste materials are disposed of safely
   • The machine is checked to ensure that it is safe to operate, when cleaning is finished, and all machine guarding is replaced or repositioned in safe working order
   • Obvious faults and wear are documented and reported

Required Skills

Required skills

OHS in relation to operating machinery such as safely switching off machinery before cleaning is started communication skills by reporting and documenting obvious faults and wear planning and organising by selecting cleaning equipment and materials most suitable for the machine teamwork when maintaining the production process by working in association with others using technology when checking vacuum systems for wear cleaning them with compressed air and replacing suctions if necessary problem solving when disposing safely of used cleaning agents and waste materials

Required knowledge

common faults associated with sack or bag manufacturing machines what causes them and how to correct them enterprise documentation procedures enterprise quality standards enterprise faults procedures OHS procedures for using cleaning fluids

Evidence Required

The Evidence Guide provides advice on assessment and must be read in conjunction with the performance criteria required skills and knowledge range statement and the Assessment Guidelines for the Training Package
Overview of assessment
Critical aspects for assessment and evidence required to demonstrate competency in this unit	Evidence of the following is essential clean and check a sack and bag machine with minimum downtime according to job specifications and within the production timeframe for valid and reliable assessment of this unit evidence should be gathered over a period of time through a range of methods for assessment to indicate consistent performance in cleaning sack and bag machines evidence for assessment may be gathered from assessment of the unit of competency alone or through an integrated assessment activity
Context of and specific resources for assessment	Assessment must ensure assessment may take place on the job off the job or a combination of both of theses off the job assessment must be undertaken in a closely simulated workplace environment access to a sack or bag making machine
Method of assessment	A range of assessment methods should be used to assess practical skills and knowledge The following examples are appropriate for this unit direct questioning combined with review of portfolios of evidence and third party workplace reports of onthejob performance by the candidate
Guidance information for assessment	Holistic assessment with other units relevant to the industry sector workplace and job role is recommended
