Hello,

I just received  a new Vacuum Degassing System - Small Vacuum Pump. 
After toping the Oil as per instructions, I am running some trial runs. During these,  I noticed a significant amount of Oil in the vaccum chamber (see image below). 
Otherwise the pump pulls a vacuum. 

Is there a step I am missing which is leading to this issue ?

Many thanks,
