Precautions For Safety
Precautions for Use (Danger / Warning)
Danger
Indicates an imminently hazardous situation that, if the product is misused, may bring about death or
serious injury to the operator.
Keep flammable or explosive gas out.
Keep the pump from inhaling flammable or explosive gases. Do not use the unit in
the place where flammable or explosive gas exists. It may cause explosion or
fire.
Warning
Indicates a potentially hazardous situation that, if the product is misused, may bring about death or
serious injury to the operator.
Do not block the exhaust piping. (B type and V・B type)
Do not operate the pump while the pressure controller is totally closed or the exhaust
piping is blocked. Blocking the exhaust air may increase the pressure and
temperature in exhaust piping, and result in injury and malfunction due to burst
of the piping and pump parts.
Do not wash filter element with organic solvents.
When cleaning the filter element, do not use organic solvents such as thinner,
alcohol, benzine, gasoline, and kerosene. It may result in explosion or fire.
Do not remove the cover during operation.
Do not operate this product while the main cover is removed. Otherwise, your
hand(s) may be cut off or be seriously hurt because the cooling fan and the coupling
rotate at high speeds.
Prevent the power cord from any damage.
Do not damage, bend, pull, or bind the power cord. Do not place heavy object on it
or let it get caught or pinched. It may damage the cord, and may cause electric
shock or fire.
Keep this product away from water.
Do not pour water over the pump and the motor, and do not use water for cleaning
this product. Also, do not use this product where it may touch water or other liquid.
It may cause electric shock or fire.
Be alert to electric shock.
Do not touch electrical parts such as power plug with wet hands. Also, do not
operate switch with wet hands.
It may cause electric shock.
Never fail to put the terminal box cover on.
In the case of a motor with the terminal box, do not operate it with the terminal box
cover removed. It may cause electric shock.
Do not modify the product.
Do not modify the product.
It may cause abnormal operation and may result in injury, electric shock or
fire.
Be sure to ground this product.
Be sure to ground the product with the screw for grounding inside the terminal box or
at the lower part of the frame of the motor.
Failure to do so may cause electric shock.

Precautions For Safety
Precautions for Use (Warning / Caution)
Warning
Indicates a potentially hazardous situation that, if the product is misused, may bring about death or
serious injury to the operator.
Installation must be done by specialized personnel.
The product may fall down or drop if it is improperly installed. It may result in
personal injury, electric shock or fire.
Do not operate this product under abnormal conditions.
Stop the operation when it is abnormal. Then, pull out the power plug or shut off the
main power supply, and consult with our dealer or a specialized company. If the
operation is continued under such conditions, it may cause electric shock or fire.
Shut off the main power supply before cleaning, maintenance and
inspection.
Shut off the main power supply before cleaning, maintenance, and inspection, and
clearly post a sign on the power supply switch to indicate it is under cleaning,
maintenance, and inspection. Failure to do so may result in electric shock or
personal injury.
※Consult with a specialized company for maintenance and inspection.
Inspect the power plug periodically.
If the product is operated with the power plug, periodically inspect the power plug
and confirm it is not covered with dust. The power plug must be fully inserted to the
root of pins. If the power plug is covered with dust or not fully inserted, it may cause
electric shock or fire.
Be sure to install the protective device.
Consult with a specialized company to install an earth leakage breaker. Failure to
do so may cause electric shock or fire. Also, install an overload protection
device (thermal relay). Operation without such a device may cause
malfunction due to overload or fire.
Contact with a specialized company when the earth leakage breaker is
activated.
When the earth leakage breaker is activated, contact with a specialized company. If
you force to turn on the power supply, it may cause electric shock or fire.
Do not use this product outdoors.
This product is intended for indoor use. If the product is used outside and is
exposed to wind or rain, the motor may suffer from incomplete insulation and may
cause electric shock or fire.
Caution
Indicates a critical situation that, if the product is misused, may bring about injury to the operator or
damage to the product.
Do not use the machine over the specified pressure.
If using the machine over the specified pressure, it may shorten the life of product
and may cause failure, abnormal generation of heat or trouble.
Prohibition of operation with the vacuum pipe closed (V type and V・B type)
Do not operate the pump with the vacuum controller closed completely to close the
vacuum pipe. Negligence may cause an abnormal pump temperature rise resulting
in a product failure, protective cover deformation or burn injury.
Do not sit on, lean on, or place objects on this product.
Do not place heavy objects or object containing water on the product, and do not get
on it. If you get on the product, you may fall and be injured. If water spills, it may
cause rust inside or poor insulation and may cause leakage or electric shock.

Precautions For Safety
Precautions for Use (Caution)
Caution
Indicates a critical situation that, if the product is misused, may bring about injury to the operator or
damage to the product.
Do not operate this product with any voltage other than the rated one
specified for the motor.
Operation with any voltage other than the rated voltage specified for the motor
may
result in failure or accident.
Prevention of melting of distribution cable covering due to contact.
Install the motor so that wiring cables do not touch the motor frame.
Contacting
with cables may result in melting covering or ignition.
Be alert to burn.
Do not touch areas around the dry pump, and the exhaust port and the piping
surface of exhaust side. They are heated to high temperature, and it may result
in burn.
Inspect the earth leakage breaker periodically.
Periodically check performance of the earth leakage breaker. If using the product
with failure of the earth leakage breaker, it may cause electric shock in case of
short circuit.
Installation of check valve
Residual pressure may reverse the rotation when the pump is stopped. Be sure to
install the check valve horizontally within 50cm from the inlet port (or the exhaust
port) of pump. No installation of check valve may cause malfunction.
Turn off the main power supply in case of not using the pump for a long
time.
When you do not use the product for a long time, shut off the main power supply.
Otherwise, it may cause electric shock or short circuit ignition due to
degenerated insulation.
Be sure to wear personal protective equipment for cleaning and
maintenance.
When you carry out cleaning or maintenance, be sure to wear gloves. Failure to
do so may result in injury or burn.
When you transfer the product, be sure to wear nonslip gloves and safety shoes.
Failure to do so may result in injury.
Continuous operation is recommended.
If the start and stop frequency is high, start and stop cycle in 5 minutes or less, it
may cause significant lifetime deterioration or malfunction of the product.
