Operation

WARNING

This pump is not pressure-proof.

Do not run the Pump

on blocking the exhaust outlet or putting any device

that might hamper gas passage onto the outlet. There is a risk that the

pressure inside the Vacuum pump rises up

to cause break or oil leak of

the casing or Oil level gauge resulting in overload of the motor.

This product is not made as the withstand pressure structure. Ensured

pressure value of the Pump shall be 0.03MPaG (0.3kg/cm2

G) (Gauge

pressure).

WARNING

Do not operate the Pump

in hazardous area (where there is a risk of

creating hazardous atmosphere by explosive gas). It might cause injury

and/or fire.

WARNING

①

operation and just after stopped it while the Pump

unit keeps high

temperature. You have a risk of getting burned.

④

Should you found any malfunction or error, just turn OFF the Power

Supply to prevent accident and ask the agency or closest Service

Center for check and repair.

WARNING

①

Do not attempt to put your hand or article in the opening of the motor;

you have a risk of getting electrical shock, injury or casing a fire.

②

Do not touch any rotary section such as the motor, main spindle or

spindle joint during operation of the Vacuum pump;

it shall bring in injuries.

③

Strictly refrain from putting any combustible substance in and around

1m of the motor and Vacuum pump;

there is a risk of getting a fire.

④Do not put a wall or obstacle in and around 0.1m of the air in

let of the

motor (Motor edge face).

You have a risk of getting burned or fire caused by over heat.

0.4 Types and Descriptions of Warning Labels Displayed on This Machine and

Displayed Positions

Warning labels are attached on the warning locations in this system.

Be sure to check them before starting operation of the Pump.

Before use, read through the instruction manual and fully

understand its contents.

・

You may get an electric shock in the area around a portion

with this warning label. Before maintenance or wiring, be sure

to turn off the primary power supply.

・

Be sure to close the lid of the terminal box before operating

this unit. Never open it during operation.

During operation or for a while after operation stops, do not

touch the unit as each portion is at a very high temperature. -

If a human body touches the unit, it may get burned.

・This product is not made as the withstand pressure

structure. Ensured pressure value of the Pump shall be

0.03MPaG (0.3kg/cm2G) (Gauge pressure).

・Do not run the Pump on blocking the Exhaust outlet or

putting any device that might hamper gas passage onto the

outlet. There is a risk that the pressure inside the vacuum

pump rises up to cause break the casing or Oil level gauge

resulting in overload of the motor.

・Following gases cannot be evacuated because these gases

may cause the

pump inner pressure to increase due to internal combustion.

1) explosive gas

2) flammable gas

3) gas which increases the susceptibility of substances to

burn.

Long term storage of the Vacuum pump without operation

might possibly cause trouble in operation caused by rust i

you kept the Pump

long time without operating it, ask a closest

Service Center for the check.

Indoor Use Only

Mount at least 100mm from side walls.

Before wiring, please confirm the power-

supply voltage you

use.

Please confirm the power-supply volta

ge you'll use and

change crossline in the terminal box.

Refer to “3.5 Electrical Connection”.
