For the filter 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
Piping
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.
Blow out or clean piping before piping to eliminate swarf, cutting oil, solid foreign material.
Contamination of piping may cause damage or malfunction.
Check inlet pressure before setting up.

pressure regularly.
will disappear.)
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.
Be sure to unlock the handle before adjusting the pressure and lock it after setting the
pressure. Failure to follow this procedure can damage the handle and the outlet pressure may
fluctuate.
・Pull the pressure regulator handle to unlock. (You can visually verity this with the "orange
mark" that appears in the gap.)
・Push the pressure regulator handle to lock. When the handle is not easily locked, turn it left

The piping for drain from auto drain should be connected under the following requirements to
avoid operating failure.
threads of the end of thread exposed.
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.
Do not apply any torsional moment, or bending moment except the weight of the filter
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.
Drain guide is not equipped with valve function. Be sure to connect piping for drain. No piping
for drain allows the drain and compressed air to exhaust freely. Also, the piping should be
performed with drain guide held by spanner to prevent breakage of bowl.
