This product closes the exhaust vent with the oil cap so that the vacuum pump oil
should not leak while transporting it because it ships it by injecting the vacuum
pump oil in a regulated amount. Please remove the oil cap for transportation without
fail before starting the pump, and exchange it for the attached exhaust entrance
cap.
There is a risk of explosion. Never block the outlet or operate the pump with
equipment mounted at the outlet side which blocks the passage of gas. Otherwise,
the internal pump pressure increases causing the pump to explode, the oil level
gauge to protrude or the motor to be overloaded. This pump is not resistant to
pressure. The internal pump pressure is limited to 0.03 MPa (gauge pressure).
