Drum sander needs help

Hi



My twin drum sander (Hare and Forbes) has stopped working after many good years of service. When I now turn it on, the motor starts and after 10 seconds trips the safety switch on my switchboard.



i was hoping someone could recommend an electrician who has some experience with woodwork machinery to come out and investigate what is wrong. I am in Essendon, Victoria. So preferable to have someone on my side of town.



I have tracked down some electricians but they all seem to be on the other side of town and not too to travel.



Thanks in advance.
