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.
② Never fail to take the earth connection.
③
Ensure to close the cover of motor
terminal box and never open it during
operation.
④
Be sure to cut the electricity to do
checking or
installation.
⑤
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
(0.3
kg/
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.
When utilizing the oil mist trap, perform the
periodic maintenance so that no -
resistance can be realized in passage of
gas.
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.
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.
