The Home Machinist!

I bought this and the wires behind the machine and right below mill motor are pulled lose one is a yellow/green that i found out went to the start button the other two are blue and brown can anybody tell me the color that go to off button it does not have any two it , i think this come from the rev and forward switch i picked a manual up it shows the motor wires but no color coded and does not show rev forward switch or on off button ,if any body can help thanks

I do not know about that machine but conventions are:
Blue is the line Cold (European standard) same as the US white lead.
Brown is the line Hot, same as the US Black
Green-striped-jellow is safety ground/chassis

thanks found out today they went to that off switch
