5 Precautions Be sure to read before handling. Refer to p.0-33 to 0-3 for Safety Instructions and common precautions. Design Warning q Contact SMC if using fluids other than air. w Do not supply air pressure from 2(A) port. The air will leak to 1(P) port. e Since the valve may have slight air leakage, it may not be suitable for holding pressure in a pressure vessel. Selection Operation method: To stop the knob in a midway position can cause malfunction. Switch it to ON or OFF quickly and firmly. Mounting L type bracket mounting: Tightening torque of 0.5 to 0. N should be applied to the bolts when mounting the bracket to the body. Piping Precautions for handling the male threads of the R (PT) pipe fitting with a seal; q Use a wrench to secure the hexagon portion to screw in the fitting. If the size of the wrench is not appropriate it will be stripped. w To screw in the fitting, first hand-tighten; then, use a tool to rotate it 2 to 3 turns. If it is tightened excessively, the amount of sealing agent that protrudes will increase, so make sure to remove the sealing agent that has protruded. e Re-use of fittings: (1) Ordinarily, the fitting can be reused 2 to 3 times. (2) Using an air blower, remove the sealing agent that is peeling from the removed pipe fitting before reusing the fitting. If the peeled sealing agent enters the peripheral equipment, it could cause air leakage. (3) If the sealing effect has been lost, place a seal tape over the sealing agent to reuse the fitting. Do not use any other agent except a seal tape. One-touch fitting (1) When tubes other than SMC's are used, verify that the tube O.D. satisfies the following accuracy; Nylon tube Within ±0.1mm Soft nylon tube Within ±0.1mm Polyurethane tube Within +0.1mm, 0.2mm If the tube's external accuracy is not satisfied, it might not be possible to connect the tube or after it is connected, it could lead to air leakage or cause the tube to pull out.
