•Before starting the pump, make sure that all piping is properly connected.
•Also, before starting the pump, make sure that all the bolts are securely tightened. (Refer
to the maintenance manual for the bolts that a regulation torque is explained.)
•Make sure that the air valve, regulator and the drain valve on the discharge side are closed.
Also, make sure that the valve on the suction side is opened.
1) Start the air compressor.
2) Open the air valve in front of each piece of peripheral equipment, and adjust the supply air pressure
with a regulator to within the permissible range (see 10.1 Main specifications after p.30).
3) Open the flow valve on the discharge side.
4) Press the RESET button, and then slowly open the air valve of the pump.
5) First, verify that fluid is flowing inside the piping and is being pumped to the discharge side, and
then fully open the air valve.

•Do NOT open the air valve suddenly.
•In case of use lubricator, must be used turbine oil none addition class 1 turbine oil (equivalent
ISO VG 32 grade) for lubricants.
Do not apply lubricants more than required and also do not use any other lubricants,
which designated on this instruction manual. This may cause of pump problem and there is
danger of serious bodily damage.

•Adjust the flow valve on the discharge side. For the relationship among the flow,
supply air pressure and discharge pressure, see 10.3 Performance curve after p.52.

•As you start closing the flow valve, the supply air pressure may rise.
Make sure that the pressure is kept within the normal operating range (see 10.1 Main
specifications after p.30).
•Depending upon the viscosity and specific gravity of the fluid, the suction stroke and
other conditions, the permissible suction flow speed of fluid into the pump will vary
however, if the pump speed (flow speed of fluid) increases greatly, cavitations will occur,
and this not only will reduce pump performance, but it may cause a malfunction. Adjust
the supply air pressure as well as the flow in order to prevent cavitations.
•If fluid is not discharged after you start the pump, or if you hear an abnormal noise
or notice any irregularity, shut down the pump immediately (see 8. Troubleshooting after p.28).
