Deletion of List of manual labour tasks

Comment: Tasks of this kind have been classified and analysed by researchers and bodies such as the Department of Labor.  For example, see ''http://books.google.co.uk/books?id=Px-oj_GnFHUC&pg=PA235 Handbook for analyzing jobs'' which classifies such tasks as setting up, feeding/off-bearing, &c.  Analyses of this kind are therefore notable and should be improved rather than deleted per our |editing policy
