If the belts are not tight enough they will slip, they should all be fairly tight but not like a piano string if you know what I mean. As you do not describe what the machine is doing wrong I can not really say any more at present, except make sure there is no oil on the belts and the machine has no tight spots when you turn it over by hand.
