not sureabout then letting you take out a machine after 30mins training but (and i may be wrong)its your responsibillity and not the hire companies to make sure you are trained and have the specific licences to satisfy site needs aswell as your insurance needs, i say this as when we 1str hired we didnt have a licence but hire company said nop probs if we are prepared to take a chance, it was upto us to have licence and not for them to check, happy to be put right if i am wrong but info going on past experiance
