SMC Networks MGC Seires Operation Manual page 11

1) Operation manual
Install the product and operate it only after reading the operation manual carefully and understanding its
contents. Also, keep the manual in a location where it can be referred to as necessary.
2) Ensure sufficient space for maintenance activities.
When installing the products, allow access for maintenance and inspection.
3) Tighten threads with the proper tightening torque.
When installing the products, follow the listed torque specifications.
4) Do not place a magnetic object near the product.
The auto switch is a magnetic sensing type. If a magnetic object is placed close to it, the actuator could
operate suddenly, which could pose a hazard to humans or damage the machinery and equipment.
5) Do not perform additional machining on the product.
Performing additional machining on the product can result in insufficient strength and cause damage to the
product. This can lead to possible human injury or damage to the surrounding equipment.
6) Do not enlarge the fixed throttle by modifying the pipe connectors
If the hole diameter is enlarged, the product's rotation speed will increase, causing the shock force to increase
and damage the product. As a result, it could pose a hazard to humans or damage the machinery and equipment.
7) Do not open the cushion valve after rotating it numerous times in a row. Though uncommon, there
are cases in which the cushion valve may leak air.
The cushion valve should be adjusted by gradually opening it while checking the operation of the cylinder
cushion.
1) Be certain to align the rod axis with the load and direction of movement when connecting.
When not properly aligned, the rod and tube may be twisted, and damage may be caused due to wear on certain
areas, such as the inner tube surface, bushings, rod surface, or seals.
2) When an external guide is used, connect the rod end and the load in such a way that
there is no interference at any point within the stroke.
3) Do not scratch or gouge the sliding parts of the cylinder tube, piston rod, etc., by striking or
grasping them with other objects.
Cylinder bores are manufactured to precise tolerances, so even a slight deformation may cause a malfunction.
Also, scratches, gouges, etc., on the piston rod may lead to damaged seals or cause air leakage.
4) Do not use until you can confirm that equipment can operate properly.
Confirm correct mounting by performing function and leak tests properly after compressed air and power are
connected following mounting or repair.
5) Cantilever fastening
If a cylinder is actuated at a high speed when mounted with one side fastened and one side free (basic type,
flange type, direct mount type), the bending moment may act on the cylinder due to vibration at the stroke end,
causing damage to the cylinder. In such cases, install a mounting bracket to suppress the vibration of the
cylinder body, or reduce piston speed until the cylinder body does not vibrate at the stroke end.
Also, use a mounting bracket when moving the cylinder body or mounting a long stroke cylinder horizontally with
one-sided fastening.
6) Be very careful when handling the product.
Depending on the handling method, there is a risk that the corners of the product will injure your hands,
fingers, etc.
7) Use caution that no scratch or dent will be given to the slide part of the guide rod.
Because the outer circumference of the guide rod is manufactured with precise tolerances, even a slight
deformation, scratch, or gouge can lead to faulty operation or reduced durability.
8) When fitting the guide body, use the guide body which has high flatness of the fitting surface.
If the guide rod has twisted, operation resistance will become abnormally higher and the bearing will wear at an
early stage, thereby resulting in poor performance.
9) When mounting a workpiece to the plate, do so only when the piston rod is retracted.
Otherwise, the guide parts has twisted and lead to a malfunction.
