Precautions
Warning
- Do not use the cylinder as a shock absorber. Using the cylinder as a shock absorber will cause the cylinder to break.
Caution
- Do not open the cushion valve excessively. Excessive rotation of the cushion valve in the opening direction (counter-clockwise) may result in the valve slipping out or the mating threads becoming too short and/or breaking.
- Contact SMC if the knuckle joint must be installed on the piston rod using the rod end nut. Do not put adhesive tape or other objects on the painted surface.
- The paint on the CS cylinder is dried naturally, so it may peel if tape or other objects are placed on it.
*See the manufacturer's catalog for product information other than that detailed above.
