that nobody is present near the cylinder to be acti-
vated.
AIR QUALITY (Section 5.3)
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

ELECTRIC CIRCUITS (Section 5.4)
a) Check forthe presenceof any currentleak fromthe
external control device because it may cause an er-
roneousvalveoperation.
When a programmable controller or a similar controlde-

PERIODIC INSPECTION (Section 6.1)
Before providing a maintenance service, cut the power
and the supply of compressed air and confirm the ab-
senceofresidualpressure.
Theaboveisrequiredtoensuresafety.
Regularly perform the daily and periodic inspections to

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 solenoid valves,
readtheinstructionmanualcarefullyandunderstandthe
