INTENDED CONDITIONS OF USE
2.1 Specifications
Note 1)
In accordance with dynamic performance test of JIS B 8374-1981 (coil temperature 20ºC,
at rated voltage, without surge voltage suppressor)
Note 2)
Impact resistance
: No malfunction resulted from test using a drop impact tester. The test
was performed one time each in the axial and right angle directions of the main valve and
armature, for both energized and de-energized status
Vibration resistance
: No malfunction resulted in a 45 to 2000Hz one sweep test
performed in the axial and right angle directions of the main valve and armature, for both
energized and de-energized status.

SAFETY RECOMMENDATION
1.1 General recommendation
These safety instructions are intended to prevent a hazardous situation and/or equipment damage. These
instructions indicate the level of potential hazard by label of "Caution", "Warning" or "Danger". To ensure safety,
be sure to observe ISO4414 (Note1), JIS B 8370 (Note2) and other safety practices.
Note1: ISO 4414: Pneumatic fluid power - General rules relating to systems.
Note2: JIS B 8370:Pneumatic system axiom.
WARNING
The compatibility of pneumatic equipment is the responsibility of the person who designs the
pneumatic system or decides its specifications.
Since the products specified here are used in various operating conditions, their compatibility for the
specific pneumatic system must be based on specifications or after analysis and/or tests to meet your
specific requirements.
Only trained personnel should operate pneumatically operated machinery and equipment.
Compressed air can be dangerous if an operator is unfamiliar with it. Assembly, handling or repair of
pneumatic systems should be performed by trained and experienced operators.
Do not service machinery/equipment or attempt to remove components until safety is confirmed.
Inspection and maintenance of machinery/equipment should only be performed after confirmation of safe
locked-out control positions.
When equipment is to be removed, confirm the safety process as mentioned above. Switch off air and
electrical supplies and exhaust all residual compressed air in the system.
Before machinery/equipment is re-started, ensure all safety measures to prevent sudden movement of
cylinders etc. (Bleed air into the system gradually to create backpressure, i.e. incorporate a soft-start
valve).
Contact SMC if the product is to be used in any of the following conditions:
Conditions and environments beyond the given specifications, or if product is used outdoors.
Installations on equipment in conjunction with atomic energy, railway, air navigation, vehicles, medical
equipment, food and beverage, recreation equipment, emergency stop circuits, press applications, or
safety equipment.
An application, which has the possibility of having negative effects on people, property, or animals,
requiring special safety analysis.
CAUTION
Ensure that the air supply system is filtered to 5 micron.
1.2 Conformity to standard
This product if certified to and complies with the following standards:
3.2 Piping
CAUTION
Before piping make sure to clean up chips, cutting oil, dust etc.
When installing piping or fitting into a port, ensure that sealant material does not enter the port inside.
When using seal tape, leave 1.5 to 2 threads exposed on the end of pipe/fitting.
