Winding direction Pipe tape Expose approx. 2 threads Piping Caution Air Supply 1. Refer to the Fittings and Tubing Precautions (pages 44 to 47) for handling One-touch fittings. 2. Preparation before piping Before piping is connected, it should be thoroughly blown out with air (flushing) or washed to remove chips, cutting oil and other debris from inside the pipe. 3. Wrapping of pipe tape When screwing piping or fittings into ports, ensure that chips from the pipe threads or sealing material do not enter the piping. Also, if pipe tape is used, leave 1.5 to 2 thread ridges exposed at the end of the threads. Lubrication Caution 1. The non-lube type air gripper is lubricated at the factory, and can be used without any further lubrication. In the event that lubrication will be applied, use class 1 turbine oil (without additives) ISO VG32. Furthermore, once lubrication is applied, it must be continued. If lubrication is later stopped, malfunction can occur due to loss of the original lubricant. Refer to the Material Safety Data Sheet (MSDS) of the hydraulic fluid when supplying the fluid. Caution 1. When extremely dry air is used as the fluid, degradation of the lubrication properties inside the equipment may occur, resulting in reduced reliability (or reduced service life) of the equipment. Please consult with SMC. 2. Install an air filter. Install an air filter upstream near the valve. Select an air filter with a filtration size of 5 μm or smaller. 3. Take measures to ensure air quality, such as by installing an aftercooler, air dryer, or water separator. Compressed air that contains a large amount of drainage can cause malfunction of pneumatic equipment such as air grippers. Therefore, take appropriate measures to ensure air quality, such as by providing an aftercooler, air dryer, or water separator. 4. Ensure that the fluid and ambient temperature are within the specified range. If the fluid temperature is 5°C or less, the moisture in the circuit could freeze, causing damage to the seals and equipment malfunction. Therefore, take appropriate measures to prevent freezing. For compressed air quality, refer to SMC Best Pneumatics No.5 catalog. Warning 1. Type of fluids Please consult with SMC when using the product in applications other than compressed air. 2. When there is a large amount of drainage. Compressed air containing a large amount of drainage can cause malfunction of pneumatic equipment. An air dryer or water separator should be installed upstream from filters. 3. Drain flushing If condensation in the drain bowl is not emptied on a regular basis, the bowl will overflow and allow the condensation to enter the compressed air lines. It causes malfunction of pneumatic equipment. If the drain bowl is difficult to check and remove, installation of a drain bowl with an auto drain option is recommended. For compressed air quality, refer to SMC Best Pneumatics No.5 catalog. 4. Use clean air. Do not use compressed air that contains chemicals, synthetic oils including organic solvents, salt or corrosive gases, etc., as it can cause damage or malfunction.
