These safety icons warn the operator and others of possible dangers and damage and should always
be followed.

before working on electrical wiring, or engaging in any electrical work.
・ Cautions for Safety in Use
Applications
(1) This pump is not designed to be explosion-proof, and should therefore not be used to
discharge explosive gases. Such use may result in injury and fire.
(2) In addition to discharge of gas via the outlet, gas may also leak from other parts of the
pump, and it should therefore not be used with toxic gases. If toxic gas is discharged for
any reason it is important to note that the interior of the pump will be contaminated by the
gas, requiring appropriate caution during maintenance.
Maintenance and Repair
(3) When requesting the manufacturer’s service division to dismantle and repair the pump,
always note the gas which the pump has been used with on the Usage Check Sheet. Note
that if it has been used to discharge toxic gas for any reason it will be contaminated. Please
be aware that use with some gases will preclude dismantling and repair.
