1.1.3 Warning Electric shock
Factors
Avoidance methods and measures
Getting electrical shock on
touching the current-carrying
part of the motor.
1) Be sure to cut the electricity to do electrical
connection. Never fail to take the grounding.
2) Ensure to close the cover of motor terminal
box and never open it during operation.
3) Be sure to cut the electricity to do checking or
installation.
4) Never attempt to put in the hand or bar into the
opening of the Motor.
Motor terminal mount gets burnt
Tighten close the terminal. Check the tightening
once a month.(Refer to “3.5 Electrical
connection”)
1.1.4 Warning Explosion
Factors
Avoidance methods and measures
Pressure inside the pump rises
up and the pump explodes.
Ensured pressure value of the Pump is
0.03MPaG
(0.3kg/
cm
2
G)
(Gauge
pressure).Check the Exhaust side pressure of the
pump. If it was over 0.03 MPaG(0.3 kg/cm
2
G)(Gauge pressure) take away anything in and
around the exhaust outlet that hampers gas
passage. If you used the Oil mist trap, replace it
so that it does not hamper the gas passage.
1.1.5 Caution High temperature
Factors
Avoidance methods and measures
Getting burnt on touching the
high temperature part.
1) The Pump gets high temperature during
operation.Apply an appropriate protection to avoid
to touch the surface as necessary.
2) As the surface temperature is high, you have a
risk of getting burnt by accidentally touching it
with the hand or the like. Refrain from touching
the pump during operation. Wait until the
temperature sufficiently cools down after having
stopped the pump to conduct check or something.
3) Do not touch the Pump unit or the Motor when
operating the Gas ballast valve.
