When installing piping, avoid chips and sealing materials from piping screws entering the
inside of equipment. Or malfunction may occur. When use sealing tapes, leave 1.5 ～ 2
threads of the end of thread exposed.
Piping
Hold the female screw side and screw in piping with recommended tightening torque.
Insufficient tightening torque lead to cause loose piping or sealing failure. Excessive torque
may lead to cause screw breakage. Tightening without holding female screw side applies
excessive force to the piping bracket which lead to cause breakage.
Outlet pressure may change if regulator is used for long periods. Please confirm set pressure
regularly.
Blow out or clean piping before piping to eliminate swarf, cutting oil, solid foreign material.
Contamination of piping may cause damage or malfunction.
・ Push the pressure regulator handle to lock. When the handle is not easily locked, turn it left
and right a little and then push it. (When the handle is locked, the "orange mark", i.e., the
will disappear.)
For the regulator with the pressure gauge, do not apply pressure exceeding the maximum
scale of the pressure gauge in order to protect the gauge.
Adjust pressure incrementally. Pressure may become lower than set pressure if adjusted by
decreasing the value. Rotate the handle clockwise to raise the set pressure.
Counterclockwise to reduce the pressure. Moreover, please lock the handle after setting
pressure.
Outlet pressure may rise if eliminate the inlet pressure after pressure setting and supply
pressure again. The pressure becomes close to the set pressure after air is consumed in
outlet.

Maintenance
If the first operation is performed and defective setting and the exhaust leakage is found, it is
likely there is foreign object in an internal valve sliding surface or an internal valve seat part.
Failure to remove these parts may cause damage to internal parts.
Do not apply any torsional moment, or bending moment except the weight of the regulator
itself. External piping needs to be supported separately. Hard piping like steel tube is
susceptible to excessive moment load or vibration. Insert the flexible tube to cancel the
influence.
Maintenance and checks should be done by following the procedure in the operation manual.
Incorrect handling of the product may cause breakage or malfunction of the equipment or
device.
Use clean air. Compressed air containing chemicals, organic solvent, synthetic oil or corrosive
gas may lead to cause breakage of parts or malfunction.
Air containing too much moisture may cause malfunction. Install the air drier or the aftercooler
before the regulator.
