Why is there oil in the chamber?

If there is oil in the chamber, there are two possible reasons why:

  1. Check oil level. It should be at the half way mark in the oil-sight glass of the pump. Over -filling the reservoir can cause "back-suction" from the pump and "shoots" the oil into the chamber during air release. Also, we recommend replacing the filter after every oil change. A clogged filter could also cause oil to "shoot" into the chamber.

  2. If the machine was tilted or laid on it sides, oil can move in to the hoses and components. This oil can "shoot" itself into the chamber during the air release cycle. Please keep machine leveled.
