Safety instructions：

Work pipeline oil outlet:

1、 A7VO pump is designed for open circuit. -Project planning, installation and commissioning of axial piston unit must be carried out by qualified personnel.

2、 Before using the axial plunger unit, please read the corresponding manual completely. If necessary, you can get it from Bosch Rexroth.

3、During and shortly after operation, there may be a risk of burning of the axial piston unit (especially the electromagnet).              Appropriate safety measures (such as wearing protective clothing) should be taken. - The characteristics of the axial plunger unit may vary with different working conditions (working pressure, oil temperature) of the axial plunger element, the characteristics may change.

1、Oil nozzles and fixed threads are designed for maximum prescribed pressure. Machine or system manufacturers must ensure that the safety factor of connecting components and pipes meets the specified working conditions (pressure, flow, hydraulic oil, temperature).

2、Work pipeline nozzles and functional nozzles are only used in hydraulic pipelines.                                                Pressure shutoff valves and pressure controllers do not provide overpressure safety protection. Overflow valves will be provided in the hydraulic system.

3、The data and instructions contained here must be followed. - The product cannot be approved as a component that follows the general mechanical safety concept of ISO 13849. - The following tightening torque is used:

Install bolts:

Thread holes in the axial plunger unit:

For installation bolts with ISO metric threads in accordance with DIN 13 standard and with ASME B1.1 standard threads, we recommend that the tightening torque of each box be checked according to VDI 2230.

The maximum allowable tightening torque MG Max is the maximum value for the internal threaded holes and shall not exceed that value.

· Connector:

Use the following tightening torque:

Refer to manufacturer's instructions for tightening torque of the joints used.

· Locking screw:

For the metal locking screw attached to the axial plunger element, the fastening torque MV required for the locking screw is applied. For numerical values, see the table below.
