3.2 Environment Warning
•Do not use in an environment where corrosive gases, chemicals, salt
water or steam are present.
•Do not use in an explosive atmosphere except within the specified
rating.
•Do not expose to direct sunlight. Use a suitable protective cover.
•Do not install in a location subject to vibration or impact in excess of
the product’s specifications.
•Do not mount in a location exposed to radiant heat that would result in
temperatures in excess of the product’s specifications.
•Do not use in a place subject to heavy vibration and/or shock.
•Do not usein wet environments, where water can remove the presence
of the lubrication.
•Do not use in case of heavy dusty environments where dust can
penetrate into the cylinder and dry the grease.
•Do not allow dust layers to build up on the cylinder surface and insulate
the product.
3.3 Piping Caution
•Before connecting piping make sure to clean up chips, cutting oil, dust
etc.
•When installing piping or fittings, ensure sealant material does not
enter inside the port. When using seal tape, leave 1 thread exposed
on the end of the pipe/fitting.
•Tighten fittings to the specified tightening torque.

3.4 Lubrication Caution
•SMC products have been lubricated for life at manufacture, and do not
require lubrication in service.
•If a lubricant is used in the system, refer to catalogue for details.
3.5 Basic Circuit
•Plugging one of the ports on the actuator is considered a non-intended
use, and could relate to an increase in maximum surface temperature
above what the product specification declares.
3.6 Electrical Connection
•The product should be grounded by the piston rod and the body in
order to create an electrically conductive path to the
system/application.
•Ground the product in accordance with applicable regulations.
•Do not pass an electrical current through the product.
4 Settings
Refer to the standard product catalogue for general setup precautions.
5 How to Order
Refer to the product catalogue for ‘How to Order’.
6 Outline Dimensions
Refer to the standard product catalogue for general dimensions.
7 Maintenance
7.1 General maintenance Caution
•Not following proper maintenance procedures could cause the product
to malfunction and lead to equipment damage.
•If handled improperly, compressed air can be dangerous.
•Maintenance of pneumatic systems should be performed only by
qualified personnel.
•Before performing maintenance, turn off the power supply and be sure
to cut off the supply pressure. Confirm that the air is released to
atmosphere.
•After installation and maintenance, apply operating pressure and
power to the equipment and perform appropriate functional and
leakage tests to make sure the equipment is installed correctly.
•If any electricalconnections are disturbed during maintenance, ensure
they are reconnected correctly and safety checks are carried out as
required to ensure continued compliance with applicable national
regulations.
•Do not make any modification to the product.
•Do not disassemble the product, unless required by installation or
maintenance instructions.
•Do not use a product which looks or contains damage, this will
invalidate the certification. If damage is seen, please replace the
product immediately.
•Periodically check the product for any damage or rust appearing. This
could result in an increase in friction and lead to dangerous conditions.
Replace the whole actuator if any of these conditions appear.
•Replace the product, when air leakage is above the allowable value
given in the table below;
Allowable Leakage
Internal Leakage
10 cm3/ min (ANR)
External Leakage
5 cm3/ min (ANR)

8 Limitations of Use
8.1 Limited warranty and disclaimer/compliance requirements
Refer to Handling Precautions for SMC Products.
Caution
8.2 Obligations of the end-user
•Ensure the product is used within the specification outlined.
•Ensure that the maintenance periods are suitable for the application.
•Ensure any cleaning processes to remove dust layers are made with
the atmosphere in mind (e.g. using a damp cloth to avoid static build
up).
•Ensure that the application does not introduce additional hazards by
mounting, loading, impacts or other methods.
•Ensure that there is sufficient ventilation and air circulation around the
product.
•If the product is subject to direct heat sources in the application, they
should be shielded so that the actuator temperature stays within the
stated operating range.
Danger
•Do not exceed any of the specifications listed in Section 2 of this
document as this will be deemed improper use.
•Air equipment has an air leakage during operation within certain limits.
Do not use this equipment when the air itself introduces additional
hazards and could lead to an explosion.
•Use only Ex certified auto switches. These should be ordered
separately.
•Do not use this product in the presence of strong magnetic fields that
could generate a surface temperature higher than the product
specification.
•Avoid applications where the piston rod end and the adjoining part in
the application can create a possible ignition source.
•Do not install or use these actuators where there is the possibility for
the piston rod to impact foreign objects.
•In the event of damage or failure of any parts located in the vicinity
where this product has been installed, it is the responsibility of the user
to determine whether or not this has compromised the safety and
condition of this product and/or the application.
•External impact on the cylinder body could result in a spark and/or
cylinder damage. Avoid any application where foreign objects can hit
or impact the cylinder. In such situations the application should install
a suitable guard to prevent this occurrence.
•Do not use this equipment where vibration could lead to failure.
