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 at minimum operating pressure. Ensure there is no air
leakage.

Refer to Handling Precautions for SMC Products located on
www.smcworld.com
.
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.
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.
• Do not use this equipment where vibration could lead to failure.
