3. ADJUSTMENT
This hydraulic pump has been set and inspected according to specified input power and control.
Readjustment of all the adjusting portions may lead to the loss of functions specified for each control
and the pump proper may be excluded from the scope of guarantee. Never attempt operating the
adjusting screw, etc.
4. INSTALLATION
(1) Install the pump so that the input shaft becomes horizontal.
(2) Install the pump in a position lower than the lowest oil level in the tank to allow continuous flow of
the oil into the pump.
Since the pump is installed directly to the diesel engine, always use a flexible hose. Install the
(3)
suction pipe firmly to prevent suction of an air.
(4) Use the high-pressure type flexible hoses for the discharge ports A1~A2.
(5) After installation, fill the pump housing with the hydraulic oil.
Do not direct the external drain piping from within the oil.

5. DRIVE
(1)
Use a flexible coupling for connection to the motor.
(2) Insert the coupling firmly onto the input shaft. Do not hammer the coupling during insertion.
(3) The input shaft must rotate clockwise when viewed from the shaft end.
6. HYDRAULIC OIL
The hydraulic oil to be used must be a general petroleum, hydraulic oil or wear-resistant hydraulic oil
(ISO 3448, VG 32~56 or equivalent).
The applicable viscosity range is as follows :
Maximum allowable viscosity : 1000 mm
Minimum allowable viscosity : 10 mm
Recommended viscosity range : 15 ~ 36 mm
7. STARTING PROCEDURE
Before start up, check the following points and observe the cautions :
(1) Check if the tank has been washed clean.
(2) Check if the piping is clean and installed in such a manner as to prevent stress on the pump.
(3) Check if the piping is connected correctly according to the piping (circuit) diagram.
(4) Check if the joint and flange are correctly tightened.
(5) Check if the joint between the motor and pump is correctly installed.
(6) Check if the motor rotation direction agrees with the pump rotation direction.
(7) Check if the specific hydraulic oil is supplied though the filter and filled in the tank to the specified
position of the oil level gauge.
(8) Check if the filter has the specified filtration accuracy (10
(9) Check if the filter has been installed correctly relative to the flow direction.
(10) Check if the pump housing is filled with oil.
(11) Check if the control valve is set to the bypass position.
(12) Start the motor. If necessary, carry out warm-up operation at low speed.
Check, without any load on the system, if the actuator operates correctly.
