120 mm or less Warning 1. When clamping with the clamping position offset horizontally, ensure that the offset is 120 mm or less from the center of cylinder. With a large offset, twisting forces will be applied to the cylinder. This twisting force can potentially accelerate wear and breakage of parts with the abrasion of sliding parts. In addition, changes in the force on the cylinder parts may cause dangerous movement to occur with forceful impact. 2. Affix a protective cover in places where there is a danger of personal injury. A large gripping force is generated during clamping. If there is a possible pinching hazard, design the structure to avoid contact with the human body. 3. Securely tighten all stationary parts and connected parts so that they will not become loose. Take special care when the cylinder is installed where there is a lot of vibration, ensure that all parts remain secure. 4. Consider a possible loss of power. Measures should be taken to protect against bodily injury and equipment damage in the event that there is a loss of power to equipment controlled by pneumatics, electricity, or hydraulics. 5. Consider emergency stops. Design so that human injury and/or damage to machinery and equipment will not be caused when machinery is stopped by a safety device under abnormal conditions, a power outage or a manual emergency stop. 6. Consider the action when operation is restarted after an emergency stop or abnormal stop. Design the machinery so that human injury or equipment damage will not occur upon restart of operation. When the cylinder has to be reset at the starting position, install manual safety equipment. 7. No self-locking mechanism At air shutoff, there is no force generated to hold the workpiece. External forces will cause the workpiece to move out of place in the event that air is lost. Measures should be taken to protect against bodily injury with the hazard.
