Do not use the pump in an explosive atmosphere. Failure to do so will result
in injury or fire.
Mount vacuum valve and leak valve between the vacuum chamber and pump.
To stop the pump, always close vacuum valve and then open leak valve. If this
procedure is neglected, the pump oil fills the cylinder, making restart
difficult or causing damage to the pump. The pump oil also may flow back to
the vacuum chamber side.
Do not insert fingers or objects into the opening of the motor. Doing so may
result in electric shock, injury, or fire.
Never touch the rotating section of the motor, shaft or coupling while the
pump is in operation. Failure to do so will result in injury.
Never place combustible materials around the motor or pump. There is a risk
of fire.
Also, do not place objects which block ventilation around the motor. Abnormal
heat generation may result in burns or fire.
Do not touch the motor while the pump is in operation or when the pump is
still hot immediately after it stops. Touching it will result in burns.
Arrange wires correctly in accordance with the “Electrical Equipment
Technical Standard” and “Wiring Regulations.” Incorrect wiring may result
in fire.
If the pump ceases operation or malfunctions, turn off the power switch
immediately to prevent acidents, and ask the company from which you purchased
the pump or the manufacturer for inspection and repair.
