5 06 PM Page 347348 Series AR10 to AR60 Series AR20K to AR60 KSpecific Product PrecautionsSelection1. Residual pressure disposal (outlet pressure removal) is not possible for the AR20 to AR60 even though the inlet pressure is exhausted. When the residual pressure disposal is per-formed, use the regulator with a backflow function (AR20K to AR60K). WarningMaintenance1. When using the regulator with backflow function between a solenoid valve and an actuator, check the pressure gauge peri-odically. Sudden pressure fluctuations may shorten the durabil-ity of the pressure gauge. A digital pressure gauge is recom-mended for such situation or as deemed and Adjustment1. Set the regulator while verifying the displayed values of the in-let and outlet pressure gauges. Turning the regulator knob ex-cessively can cause damage to the internal The pressure gauge included with Regulators for to MPa setting is for up to MPa use only (except the AR10).

6 Exceeding MPa of pressure can damage the Do not use tools on the pressure regulator knob as this may cause damage. It must be operated Be sure to unlock the knob before adjusting the pressure and lock it after setting the pressure. Failure to follow this proce-dure can cause damage to the knob and the outlet pressure may fluctuate. Pull the pressure regulator knob to unlock. (You can visually verify this with the orange mark that appears in the gap.) Push the pressure regulator knob to lock. When the knob is not easily locked, turn it left and right a little and then push it (when the knob is locked, the orange mark , , the gap will disappear).2. A knob cover is available to prevent careless operation of the knob. Refer to page 389 for markBe sure to read before handling. Refer to front matters 42 and 43 for Safety Instructions and pages 287 to 291 for Precautions.
