AIR QUALITY (Section 5.2)
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.
PERIODIC INSPECTION (Section 6.1)
Before providing a maintenance service, cut and the sup-
ply of compressed air and confirm the absence of residu-
al pressure.
The above is required to ensure safety.
Regularly perform the daily and periodic inspections to
correctly maintain product performance.
If the product is not correctly maintained , product per-
formance may deteriorate dramatically, resulting in a
shorter service life, fractures of components, and mal-
functions.
DISASSEMBLING AND REASSEMBLING (Section 6.2)
Before disassembling and reassembling master valves,
read the instruction manual carefully and understand the
instructions.
A person who disassembles and reassembles a master
valve system needs to have a knowledge for safely per-
forming such operation based on the understanding about
the mechanisms and operating principles of master valves.
Personnel involved ｉｎ this step must have passed the
Pneumatic Pressure Skill Test Class 2 or higher.
