●Circuit configuration
qThe basic configuration comprises a NACHICCO
) as a standard product plus external
(NSPmanifold (circuit).
wPiping should be arranged with a sufficient
deflection between the NACHICCO and external
manifold.
■ We recommend use of a hose having a normal
pressure of 14 MPa {2027 psi} and a length of
about 1 through 2 meters (40~80 inch).
■ The maximum peak pressure (set pressure +
surge pressure) should not exceed 14 MPa {2027
psi}.
■ When the pressure rises above 14 MPa {2027
psi} , install a relief valve for surge cutting on the
circuit side.
qWhen a manifold block (optional) is mounted on the
pump, the total weight of the block and valve should
not exceed 15 kg (33.07 lbs).

●Specifications for painting
qThe inner and outer sides of the tank and motor
portion are provided with melamine resin baking,
and the pump portion is provided with lacquer
blowing. Their color conforms to Fujikoshi standard
color (Munsell NO.5B6/3).
wFor the color of exterior features, consult our
company.

Notes:
1. For 5.0 MPa {724 psi} of a 1.10-liter
tank, it should be noted that there is a
big rise in oil temperature under
continuous operation. In this case, we
recommend use of a 20-liter tank.
2. Rise of oil temperature depends on the
conditions of using an actual machine,
and so may be different from the above
description in some cases.

Handling procedure
●Precautions in startup
qCheck if the tank is filled with hydraulic oil up to the
specified level.
Å Upper limit, Yellow mark: specified oil level (nominal
capacity)
ıLower limit, Red mark: minimum oil level
Hydraulic oil: Based on general mineral oil,
ISO VG32 or its equivalent
wElectric connection should be made correctly according
to the following procedure:

motor side
and power
supply side
U➞R
V➞S
W➞ T
a
If electric connection is incorrect:
¡The motor pump rotates in the reverse
direction without discharging oil. If the
operation is continued, the pump may
be damaged.
¡Use the pressure gauge mounted on
the discharge side and make sure that
pressure rises.
eRepeat the procedure of starting and stopping the
motor. Remove air from inside the pump and suction
pipe. (You can remove air more quickly if you remove
loads from the circuit.)

Note: Do not touch any screw except for the above-mentioned adjusting screw.
●Maintenance and inspection
qOil temperature: Use it at the temperature from 10 to 60 °C .
wHydraulic oil replacement interval: Replace hydraulic oil
three months after the start of operation in the
beginning. Then replace it whenever contamination
has been observed or after the lapse of one year.
eInspection and cleaning of tank interior and strainer:
every 6 months or every 4000 hours (whichever comes
first)
●Ambient temperature
qTemperature: 10 to 35 °C
wDo not use the mist of water soluble coolant.
