Read safety precautions starting on page 6 before performing trial operation.

（1） Check that the power voltage is at the specified voltage.
（2） Set the pressure adjusting handle to the lowest state during trial operation, and check the turning direction of the

pump in inching (shortly turn on and off the switch). When it is rotating in the reversed direction, change the
connection of 2 cables out of the 3 cables.

（3） As for the operating pressure for chucking, first lower to the lowest pressure, and then set to low pressure at
which the chucking action is possible (0.35-0.5MPa) to check the following.
○Is it operating smoothly?
○Is the operating direction correct? (Opening and closing direction of the chuck)
○Is the operating stroke appropriate? (Jaw stroke of the chuck)
○Is there any oil leakage with each piping?
If they are normal, gradually raise the operating pressure up to the rated pressure while checking the items
specified above.
At this point, check that the drainage is flowing smoothly.
（4） Rotate the lathe spindle by setting the rotation speed to the minimum. If there is no run-out of the cylinder or no

abnormalities in the support and piping, gradually raise the rotation speed.

If the rotation vibration is too excessive, run-out of the adapter must be inspected again.
（5） If the oil temperature is low (20-30℃) or less, run it in at about 1/3 of the maximum rotation speed.

＜Treatment when the cylinder cannot be operated＞

○ Regardless of trial operation or normal operation, when the cylinder cannot be operated, try the operations specified

below.

1. When the lathe spindle is rotating, stop rotation.
2. Turn the pressure adjusting handle of the pressure regulation valve for the chuck setting pressure (cylinder setting

hydraulic pressure) at the hydraulic unit part, and raise the chuck setting pressure for about 0.5 MPa and repeat

switching over the operation selecting switch of the cylinder to check the operation of the cylinder.
3. If the operation inability still continues, raise the chuck setting pressure additionally (about 0.5 MPa at a time), and

repeat the operation in the same manner as item (2), to check the action of the cylinder. In this case, the limit of the
pressure raising is up to 30% increase of the maximum operating hydraulic pressure.

When the cylinder operation is recovered, bring back the preset chuck pressure to the normal level.
4. If the cylinder cannot be operated even after the chuck setting pressure is raised to the maximum and the operation

specified in the above item (3) is repeated several times, return to the chuck setting pressure, turn off the power
supply, cool down the temperature of the cylinder surface to be almost the same as the room temperature, and
then repeat the operations specified in the above items (2) and (3) to check the operation of the cylinder.

The cylinder can be cooled down more quickly by forcibly blowing air to the cylinder using an air gun, etc.
5. If the cylinder cannot be operated even after cooling down, loosen the draw nut on the chuck side and remove the

connection, and then check the operation of the cylinder.

＜Usage＞

This product is a hydraulic device to control the operation of power chuck installed on the lathes or rotary tables.
The piston moves forward and backward by supplying hydraulic pressure to the cylinder. By this, the linked jaws of the
power chuck move toward the closing side to grip the workpiece, so that the workpiece is clamped during the
machining. After the machining, the jaws move toward the open side to allow the workpiece to be removed.

If any malfunction occurs, return cylinder to our company for repair. If it is disassembled and reassembled at a place
other than our company, it may not function correctly as well as cause precision failure.

○ Clean the suction strainer every 2 to 3 months.
○ Replace the hydraulic oil about once every six months.

5 . Trial Operation

6 . Maintenance and Inspection

・When the ambient temperature of the cylinder suddenly rises, for example, thermal effect is received from

heating of the pulley, etc., or when there is a special heat generation source around the cylinder, the cylinder
charged pressure rises and then the cylinder may stop operation, if it is continuously operated for a long period of
time without switching operation, since a lock mechanism is built in such a phenomenon occurs more frequently
especially at the time of running in, therefore, frequently reciprocate the piston.
