  • WARNING! 1. Safety Measures

    WARNING! 2. Installation and Operation Environment

    1.1 Handling Cylinders Ensure that only personnel with sufficient knowledge and experience handle cylinders. Compressed air can be dangerous if dealt with improperly. Ensure that only personnel with sufficient knowledge and experience assemble, operate, maintain, etc. machines and equipment that utilize pneumatic equipment.

    1.2 Confirming Safe Conditions Never attempt to handle machines or equipment, or remove machinery before safety is ensured. Please confirm that the actuated body’s anti-drop and run-away prevention measures are in place before inspecting or servicing machines and/or equipment. When removing machinery, confirm the aforementioned safety measures, then shut off the power to the supply air- which is the energy source - and any applicable equipment, exhaust all compressed air within the system, and make sure the valve’s internal pressure and temperature have dropped. Confirm operation safety precautions (cylinder operation, valve opening and shutting, electrical leakage, etc.) before restarting the machines and equipment.

    1.3 Cylinder and Valve Attachments Design Ensure that no thrust load or lateral load has joined to the cylinder’s output shaft when attaching. To prevent axial movement of the rotation shaft on the valve side from occurring, please install an independent stopper. Never apply the stopper on the rotation shaft to the cylinder’s output shaft. Furthermore, when the dimensions for insertion of the cylinder’s output shaft are too small, contact pressure on the fitting increases and the clearance gap will expand; it is possible that slippage may occur in the working position of the work load; therefore, it is important to ensure that the dimensions for insertion are adequate.

    1.4 Mechanical Backup If loss of all functionality due to pneumatic pressure occurs, to safely activate the cylinder, please adopt a method of operation which utilizes a different energy source, such as a Springback cylinder (hereinafter referred to as a single- acting cylinder).

    2.1 Maximum Operating Speed Do not exceed the maximum operating speed listed in the catalog. With regard to work load conditions, the cylinder may break or become damaged due to inertial force. Furthermore, water hammer may occur even if within the range noted in the catalog, due to pipe and valve operating conditions.

    2.2 Installation Space Perform installation work and maintenance at easy-to-work sites/locations.

    2.3 Operation Confirmation Procedure First, verify that the cylinder unit itself is not malfunctioning. Next, ensure that the thrust load and lateral loads of the output shaft are not joined when coupled with the work load. Also, confirm that there are no abnormalities such as air leaks in the output shaft and piping connections, then proceed to install the equipment. Lastly, confirm operation of all the equipment.

    2.4 Residual Pressure As there is a jet of compressed air going to the cylinder, unexpected movements of the cylinder may occur due to residual pressure even after air has been exhausted from the equipment; it is important to understand the risks when operating, even during installation.

    2.5 Training Ensure that installation and maintenance of cylinders is performed by personnel with sufficient knowledge and experience.
