Installation and Piping
1. When the motor is installed its shaft should face downward.
2. The motor must be installed that it is concentricity below 0.05 mm.
3. The tightening torque of bolts for mounting the motor to the bracket is shown in assembly drawing the customer’s reference.
4. Since the casing inside is always kept filled with oil, the drain must be returned to the tank through the return pipe which is once raised higher tank that of the motor itself as shown in Figure 8.
5. Motors will tolerate in the casing pressure up to maximum 3 kg/cm2, but for common pressure, 2 kg/cm2 below must be kept.
6. Piping must be cleaned and flushed well.
7. Be care to as the installation to piping.
8. Use the drain pipe bigger than the port size and short as possible.

Oil Filling and Air Ventilation
1. Fill in the casing with oil using the drain port before operating.
In the motor, there are many kinds of high-speed sliding surface like bearing, piston, shoe, spherical bushing, and etc. So If there isn’t enough oil, it can cause problems like sticking or breaking in those parts.
2. All the air in the motor and circuit must be removed, otherwise, it will be likely to be cause of imperfect working or damage of the motor.

Instructions Before Starting to Operate
1. Check that the direction of revolution is correct.
2. Check for oil leaks from the motor.
3. If the equipment vibrates abnormally or not during operation or when the revolution direction is changed.
4. If the oil temperature rises rapidly despite running for a short period of time.
5. Whether the pressure varies to a great extent as compared with the established one.
6. If the piping is fully connected or not.
