Maintain screen printing machines
Overview
This standard is for screen printers whose responsibility includes maintaining multiple-station machines in useable condition. It includes all routine tasks such as squeegee fitting and setting, routine cleaning, replacement of common worn parts and record keeping.
This standard may only be assessed in the workplace and simulation is not permitted.
Consistent quality work and productivity on a screen-printing machine can only be achieved if it is properly maintained and adjustments made where necessary. Most adjustments and settings are regarded as the responsibility of the printer, including stencil fitting, squeegee fitting and setting, and ensuring drying equipment is working properly, for example.
A thorough understanding of the machine functions and operation, operator adjustment and settings is required.
Performance criteria
You must be able to:
Keep multiple-station screen printing machinery in a clean and safe operating condition
- clean machinery following manufacturer's instructions and 'safe system of work' or 'code of practice'.
- check it is safe to start cleaning activities, including checking that others are not working elsewhere on machines
- supervise cleaning work of any machine assistants under your direction following standard operating procedures
- run machinery to clean it, check guards are in place and functioning before starting work
- isolate machinery before cleaning following standard operating procedures
- use cleaning equipment and materials suitable for machines
- remove any build-up of materials and dust in or around machines following standard operating procedures
- clean filters, feeders, conveyors, belts, squeegees, and ink delivery systems following standard operating procedures
- use personal protective equipment following standard operating procedures
- dispose of used cleaning agents and waste materials following current environmental regulations
- check machinery is safe to operate, and all guards are fitted when you have finished cleaning.**
Implement a programme of lubrication and maintenance for multiple-station screen printing machines
**
12. obtain schedules of maintenance for machinery following standard operating procedures
13. identify lubrication points on machinery and manufacturer's recommended types of lubricant and lubrication intervals
14. check maintenance plans are implemented and kept up to date following standard operating procedures
15. replenish and use lubrication equipment following standard operating procedures
16. identify filters on machinery and associated equipment following standard operating procedures
17. check filters are cleaned and/or replaced following standard operating procedures
18. examine machinery for defective components or excessive wear at regular intervals
19. remove and replace defective or worn components following standard operating procedures
20. keep records of faults that occur or are developing and check that action is taken to deal with them
21. check squeegees are in serviceable condition and set to the manufacturer's specification
22. maintain a list of parts or consumables likely to require periodic replacement and identify those parts required at short notice
23. check parts or consumables identified as being required to be kept 'in stock' are available in the required quantities.
