Before wiring, read the instruction manual carefully and
understand the instructions.

A person who wires needs to have knowledge for safely
performing such operation based on the understanding
about the mechanisms and operating principles of solenoid
valves.
Before supplying the power, check the power supply
voltage and the current type (AC or DC).
a) Once the manual operating device has been operated,
always return it to its origin (initial position), and then
start the operation of the device.
b) Before using the manual operating device, make sure
that nobody is present near the cylinder to be acti-
vated.
a) Do not supply anything other than compressed air.
b) Supply clean compressed air without any mixture of
corrosive gas.
a) Compressed air usually contains a large amount of
drain, oxidized oil, tar, foreign matter, and rust from
the piping. Filter out those elements in the supplied
air because they may cause a malfunction and de-
crease service life. In addition, clean the exhaust
before it is released to the air to minimize pollution.
b) Once you have lubricated a pre-lubricated valve, the
valve is no longer capable of running without being lu-
bricated from the outside. Do not leave the valve
without lubrication but keep it lubricated.
c) Do not use spindle oil or machine oil. They may in-
duce expansion of the rubber parts, which may cause
a malfunction.
