Sometimes the sucked oil leaks out of the muffler.
This always happens when:
Fig.16- When oil is sucked keeping air continuously connected to the equipment and the transparent
chamber is filled over the STOP mark on the bowl.
Fig.17- When oil is discharged from the transparent bowl into the lower reservoir without opening
valve B (turning it counter clockwise). It is not necessary to open the valve B only when the lower
reservoir is depressurized (when there is a vacuum).

Fig.18- When the equipment is moved and the transparent chamber is full of oil.
Oil splashes can dirty the Venturi group.
Fig.19- In these cases proceed as follows:
-remove the muffler, dismantle it and clean all the components.
Fig.20- Hold a rag as indicated, connect the compressed air to the device until all the oil comes out of
the Venturi group.
-Reassemble and mount the muffler again.
