Precautions
- Piping: Do not force a connection in a way that lateral force is applied to the cylinder tube. This could cause the cylinder tube to slant and malfunction.
- Mounting: Do not install by directly grasping the cylinder tube. This could cause the tube to deform and malfunction. Do not install by directly grasping the piston rod with pliers, etc. Scratches on the piston rod will cause damage to the bearing or rod seal, resulting in malfunction and air leakage.
