0. Introduction
0.1 Before using the MBS-053/MBS-053-01
Thank you for purchase of mechanical booster vacuum pump model
MBS -053/MBS-053-01.
This pump is only for vacuum pumping, and may malfunction or cause accidents if
not handled appropriately. Please use instruction manuals after attention enough
for check / maintenance / security sides after a reading well.
Personnel Handling the Equipment
The handling of this product has you read this instruction manual, and a
person understood enough shall perform attention in the security, the
specifications of this pump and a matter about operation method.
Read the Manual Thoroughly
This product please uses instruction manuals after a reading before use
definitely well. Please read the [to have you use it safely] [instructions in the
security] in particular by all means.
Keep This Manual in a Safe Place
Please keep the instruction manual carefully. Please keep it by all means in
the place that used one can read after having read.
Copying This Manual Is Prohibited
No part of this instruction manual may be copied for use by a third party
without our permission.
Statutory Requirements for Disposal
Follow state law and local government regulations for disposal of the pump.

－02－
Safety During Repair
When it is asked us for repair, please inform the use situation of having
hazardous substance or not in particular for the safe management of the
repair worker.
The use situation declines repair in the case of lack of foresight.
Confirmation at the time of the unpacking
Although the pump is delivered with great care, check the following after
unpacking.
(1) The delivered pump is in accordance with your request.
(2) The specified accessories (enough pump oil to use the pump once; optional
equipment) have been provided.
A normal accessory is vacuum-pump oil and a connector of power supply
voltage change use and a power cable is an option parts.
(3) No parts have been damaged in transportation.
(4) Neither screws nor nuts have become loose nor were lost in transportation.
If there are any problems, contact the company from which you purchased the
pump or the sales department of the manufacturer.

0.2 Safety symbols
In this instruction manual and on warning labels attached to the pump, the
following symbols are used so that matters which must be strictly adhered to can
be readily understood.
These symbols are divided as shown below.
Danger
When mishandled, there is an imminent danger of the operator suffering a
fatal accident or serious injury.
Warning
When mishandled, there is a possibility of the operator suffering a fatal
accident or serious injury.
Caution
When mishandled, there is a possibility of the operator suffering an injury
(light or medium injury) or of damage occurring to property.
Note
When mishandled, there is a possibility of the pump being damaged or
malfunctioning.
High temperature Caution
Some parts of the pump may reach temperatures of 90°C or more during
operation. Touching such components may result in burns.

－04－
Electric Shock Caution
The Inlet pipe of the pump
The Outlet pipe of the pump
Always switch off the main power supply before installing electrical wiring or
performing any electrical work on the pump. Failure to do so may result in
electric shock.

－05－
0.3 Cautions for safety
Never allow people other than repair engineers to disassemble or repair the
pump. Failure to do so may result in ignition or malfunction, leading to
injury or electric shock.
Connect the earth wire correctly. It is recommended that a dedicated earth
leakage breaker should be installed. If the earth wire is not connected, there
is a possibility of electric shock occurring in the case of a malfunction or
electrical leakage.
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).
The Vacuum Pump Unit is device a built-in device. Do not install it without
adequate protection against heat hazard. The surface temperature of the
vacuum Pump Unit can exceed 90 degrees in case it is operated under high
pressure (atmospheric to 10kPa).
It gets an electric shock touching the motor energizing part. Please work
after pulling out the power plug without fail when wires electricity is
connected, it checks, and it transfers it.
Do not run with opening a cover of the driver box. It causes electric shock
and the ignition.
Do not use the pump in an explosive atmosphere. Failure to do so will
result in injury or fire.

At the time of shipping, set electric voltage by request in an order. Do not
run by 200-240V line source as 100-120V system connection. Power supply
circuit is damaged when you install wrong power supply voltage selection
connector and in addition of ignition might. In order to operate with
200-240V class, the changeover connector in the terminal box must be
changed into 200-240V class as shown in fig.4.3“Changing the voltage
class.”
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 accidents, and ask the company from which you
purchased the pump or the manufacturer for inspection and repair.
Do not operate the pump without adding pump oil. If it is operated in an
oil-less condition, the pump will be damaged.
