This hydraulic unit incorporates a safety valve, and its factory default pressure is set to the maximum
operating pressure of the hydraulic unit + 0.5 MPa. Adjust the set pressure of the safety valve according to
the application. The same applies when the surge pressure upon operation of actuators has to be kept to a
minimum.

Note also that the set pressure of the safety valve may drop due to repeated protracted operation of
the machine or contamination in the hydraulic oil. If the product is used continuously with the safety
valve actuated, an alarm may occur due to temperature rise for example. In this case too, carry out
readjustment.
If the operating pressure is changed, the rotation speed also changes.

Minimum Rotational Speed Adjustment Instructions
Restrict continuous use at the maximum pressure to 5 L/min or less. The factory default setting is the
maximum flow rate.
The pressure and flow rate can be set beyond the adjustment ranges stated above, but be sure to use the
product within the operating pressure range and operating flow rate range stated above.
Refer to the specification documents (External dimension sheet) for other specifications.

DANGER
The wiring work must be done by a qualified electrical engineer. Otherwise, there is
a risk of electric shock or fire.
Personnel doing wiring work must wear gloves and long sleeves and implement
safety measures to avoid injuries such as grazes.
Personnel doing wiring work must wear gloves and long sleeves and implement
safety measures to prevent electric shocks and fire due to static electricity.
Complete the installation before starting the wiring work. Otherwise, there is a risk of
electric shock and fire.
Check that the input power supply is OFF before starting the wiring work.
Otherwise, there is a risk of electric shock.
When carrying out wiring work again after the power has been ON, check that the
motor is stopped, and wait at least 5 minutes after powering OFF before starting
the work. Otherwise, there is a risk of electric shock.
Use an EN60947-2-compliant no-fuse breaker and earth leakage circuit breaker
(with overcurrent protection). Otherwise, there is a risk of electric shock and fire.
