1. Excessive drainage Compressed air containing large amounts of drainage can cause malfunction of pneumatic equipment. As a countermeasure, install an air dryer or drain catch before the filter. 2. Drain flushing If the drain removal from air filter is missed, drain will be flown out to the outlet side and may result in a malfunction of the pneumatic equipment. When removing drain is difficult, use of a filter with an auto drain is recommended. Refer to SMC's “Air Cleaning Equipment” catalog for further details on compressed air quality. 3. Use clean air. If the compressed air includes chemicals, synthetic oils containing organic solvents, salt or corrosive gases, etc., it can cause damage or malfunctions in the system. 1. Install an air filter. Install an air filter upstream, near the valve. Select an air filter with a filtration degree of 5 μm or finer. 2. Compressed air containing large amounts of drainage can cause malfunction of pneumatic equipment. As a countermeasure, install an aftercooler, air dryer or drain catch. 3. Ensure that the fluid and ambient temperature are within the specified range. If the fluid temperature is 5°C or below, the moisture in the circuit could freeze, causing damage to the seals and leading to equipment malfunction. Therefore, take appropriate measures to prevent freezing. Refer to SMC's “Air Cleaning Equipment” catalog for further details on compressed air quality. 6. Do not use in environments where there is direct contact with liquids such as cutting oil, lubricating oil or coolant oil, etc. Consult SMC regarding use in environments where there will be direct contact with cutting oil, lubricating oil or coolant oil, etc. 7. Do not use in locations influenced by vibrations or impacts. This may cause air leakage and fitting damage. Consult SMC regarding use in this kind of environment. 8. Do not use in places or environments where foreign matter sticks to the product or gets inside the product. It may cause air leakage or tube release. 1. Do not use in atmospheres of corrosive gases, chemicals, salt water, water, steam, or where there is direct contact with any of these. 2. Do not use in direct sunlight. 3. In locations near heat sources, protect against radiated heat. 4. Do not use in locations where static electric charges will be a problem. Consult with SMC regarding use in this kind of environment. 5. Do not use in locations where spatter occurs. There is a danger of spatter causing a fire. Consult with SMC regarding use in this kind of environment. 1. Follow the procedures given in the operation manual to perform a maintenance inspection. Improper handling could lead to malfunction or damage the machinery and equipment. 2. Maintenance work If handled improperly, compressed air can be dangerous. Assembly, handling, repair and element replacement of pneumatic systems should be performed by qualified personnel only. 3. Drain flushing Remove drainage from air filters regularly. 4. Removal of equipment, and supply/exhaust of compressed air When components are removed, first confirm that measures are in place to prevent workpieces from dropping, run-away equipment, etc. Then, cut the supply pressure and power, and exhaust all compressed air from the system using the residual pressure release function. When machinery is restarted, proceed with caution after confirming that appropriate measures are in place to prevent cylinders from sudden movement. 5. Be absolutely sure to wear safety glasses when conducting periodic inspections. 6. Check for the following during regular maintenance, and replace components as necessary. a) Scratches, gouges, abrasion, corrosion b) Leakage c) Twisting, flattening or distortion of tubing d) Hardening, deterioration or softness of tubing 7. Do not repair or patch the replaced tubing or couplers for reuse. Do not disassemble the S coupler.
