About this product and this instructions manual
To use this product for many years, be sure to read this instructions
manual before installation, operation, inspection, or maintenance of this
product and fully understand the safety precautions, specifications, and
operation method of this product.
This product is supposed to exhaust inactive gas (air, nitrogen, argon)
so exhaust of other gas (toxic gas, combustion gas, flammable gas,
corrosive gas, explosive gas) is extremely dangerous. Do not exhaust
any gas with these properties.
If combustion/flammable/explosive gas is sucked in the vacuum pump, it
is extremely dangerous because the residual gas or products may cause
ignition/explosion not only in operation but also after a stop. Do not
exhaust any gas with these properties.
If toxic gas is sucked in the vacuum pump, it goes without saying that
not only the pump body but also the pump oil will be toxic. Take care
during the maintenance work.
If the details on the hazardous substances you have used are not
disclosed, or if substances that are hard to detoxify are exhausted, we
may refuse maintenance and other operations at your site.
Note that the specifications, prices, etc. of the product and the
description of the instructions manual are subject to change without

instructions manual is updated and the document is released as a
revised version.
