Warning
Explosion
Cause
Prevention method and measures
The pressure in the pump
increased causing the pump to
explode.
⇒
The maximum internal pump pressure is
0.03[MPa](gauge pressure).Measure the
pressure at the outlet side and, if the
pressure is 0.03[MPa]or more (gauge
pressure); remove objects which block the
passage of gas from the outlet side.
Warning
This pump does not become the withstand pressure structure. The limit value
of the inside pressure of the pump is 0.03 MPa (gauge pressure). Pressure in
the pump rises when the pump is driven with the equipment that obstructed the
street of the gas to blockage and the exhaust entrance side of the exhaust vent
put up
，
and there is a thing that the motor becomes an overloaded.
1.2 Safety Data Sheet (SDS)
The attached “Safety Data Sheet (SDS)” shows chemical materials which may
be used or touched when operating the pump. Read the SDS carefully in order
to understand the harmful properties of these materials.
Contact us before using chemical materials (vacuum pump oil) other than
those mentioned in this instruction manual.
Caution
SDS is submitted as reference information to ensure safe handling of
hazardous and harmful materials. Personnel handling the pump oil should be
aware that proper measures must be taken depending on the conditions of
use as their responsibility. Keep in mind that the SDS itself is not a warranty
for safety. Newest SDS shall be used when the safety of material is
investigated
