First thing is to make sure the motor drive is the right direction. There is an arrow on the main drive pulley.

The Tos SN 40 has a gear pump
So direction is important
At the back of the machine you have a pulleyshaft
at the other end of that shaft there is the pump
the oil should be visable in the oilsight and should just reach the lower shaft with the couplings
Also air trapped in the system might be the problem
There are some point on the pump to pure it
Manual is available on that french site mentioned in the sticky in the manauls section on PM

Thanks Peter, Really appreciate the information. Have been trying to get this information without success for a while now..Your response is of great help.
I changed the motor from three phase to single phase, therefore that has to be where i went wrong.
