General Instructions

The pump A4VG is designed to be used in closed circuit.

The project planning, installation and commissioning of the axial piston unit requires the involvement of qualified person- nel.

Before using the axial piston unit, please read the corre- sponding instruction manual completely and thoroughly. If necessary, these can be requested from Bosch Rexroth.

During and shortly after operation, there is a risk of burns on the axial piston unit and especially on the solenoids. Take appropriate safety measures (e. g. by wearing protective clothing).

Depending on the operating conditions of the axial piston unit (operating pressure, fluid temperature), the characteris- tic may shift.

Service line ports:

The ports and fastening threads are designed for the speci- fied maximum pressure. The machine or system manufac- turer must ensure that the connecting elements and lines correspond to the specified application conditions (pres- sure, flow, hydraulic fluid, temperature) with the necessary safety factors.

The service line ports and function ports can only be used to accommodate hydraulic lines.

The data and notes contained herein must be adhered to.

The product is not approved as a component for the safety concept of a general machine according to ISO 13849.

The following tightening torques apply:

Fittings:

Observe the manufacturer’s instructions regarding the tightening torques of the fittings used.

Mounting bolts:

For mounting bolts with metric ISO thread according to DIN 13 or thread according to ASME B1.1, we recommend checking the tightening torque in individual cases in accor- dance with VDI 2230.

Female threads in the axial piston unit:

The maximum permissible tightening torques MG max are maximum values of the female threads and must not be exceeded. For values, see the following table.

Threaded plugs:

For the metallic threaded plugs supplied with the axial pis- ton unit, the required tightening torques of threaded plugs MV apply. For values, see the following table.
