Operation
4.1 Cautions
for operation
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).
It leads to the trouble of the pump when I use it with having breathed in water.
When this absorbed the medicines such as acid / the solvent in this vacuum pump,
an oil level gauge jumps out. In addition, This causes the pomp rock. Please change
pumps oil.
4.2
Start of operation
To start operation, close leak valve (B), open vacuum valve (A) to the inlet port, and
turn on the power switch. Then the pump starts beings to exhaust. (see Figure2.)
Never insert hands, fingers, or thin objects through the motor opening.
The motor and pump become hot (temperature increase under non-load operation: 35K,
temperature increase under high-load operation: 40K) during operation of the pump.
There is a risk of burns. Never touch the motor or pump during operation.
If operation is performed at high pressure, oil mist is generated at the exhaust
side. Install an oil mist trap or connect a duct to discharge the oil mist outside
the room. Or, install a ventilator.
