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.
•Periodically check the condition of the rod seal and forthe presence of
lubrication, where possible. If these areas appear to be dry, please
follow the lubrication procedure.
•Replace theseals, 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)

7.5 Reassembly Procedure
•Inserting the collar assembly into the piston rod assembly.
Apply grease to the end of the piston rod, especially on the 30° chamfer
and on the flats. Insert with care the piston rod into the rod cover to
prevent any damage to the rod seal.
•Inserting piston rod assembly and rod cover assembly into the cylinder
tube.
Insert slowly with care the piston assembly and the rod cover assembly
into the cylinder tube to prevent any damage of the piston seal and tube
gasket.
•Installing retaining ring.
Use appropriate pliers (tool for C-Shape Snap Ring) for installation.
Caution
When installing the retaining ring, be aware that the snap ring may come
off the pliers and could result in operator injury or equipment damage.
Also make sure the ring is firmly seated inside the ring groove before
removing the tool.
•Checking Assembly.
Make sure that no air is leaking form the rod seal and that the cylinder
operates smoothly atminimum operating pressure. Ensure there is no air
leakage.
8 Limitations of Use

stated operating range. Caution
•SMC products are not intended for use as instruments for legal
metrology.
Measurement instruments that SMC manufactures or sells have not
been qualified by type approval tests relevant to the metrology
(measurement) laws of each country.
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 ATEX 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.
