Specific Product Precautions
Selection
1. 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 perfor-
med, use the regulator with a backflow function (AR20K to
AR60K).
Warning
Maintenance
1. When using the regulator with backflow function between a so-
lenoid valve and an actuator, check the pressure gauge perio-
dically. Sudden pressure fluctuations may shorten the durabi-
lity of the pressure gauge. A digital pressure gauge is recom-
mended for such situation or as deemed necessary.
Warning
Mounting and Adjustment
1. 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 parts.
2. The pressure gauge included with regulators for 0.02 to 0.2
MPa setting
is for up to 0.2 MPa use only (except the AR10).
Exceeding 0.2 MPa of pressure can damage the gauge.
3. Do not use tools on the pressure regulator knob as this may
cause damage. It must be operated manually.
Warning
1. Be sure to unlock the knob before adjusting the pressure and
lock it after setting the pressure. Failure to follow this procedu-
re 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”, i.e., the gap will
disappear).
2. A knob cover is available to prevent careless operation of the
knob. Refer to page 90 for details.

tions and F.R.L. Units Precautions.
