Bosch Rexroth 10 Series - Performing Flushing Cycle

RE 91485-01-B/2021-11-18, BoschRexrothAG
Installation | A10FZO/G, A10VZO/G 53/72
This can be supplied by BoschRexroth on request.
BoschRexroth material number: R902602623.
1� Switch off the power supply to the relevant machine/system component.
2� Electrically connect the axial piston unit (12 or 24 V). Before establishing the
connection, check the connector and all seals for damage.
If necessary, you can change the position of the connector by turning the solenoid
body. This is independent of the connector version.
CAUTION! Hot surfaces on the solenoid!
Risk of getting burnt!
▶ Allow the solenoid to cool down sufficiently before touching it.
▶ Wear heat-resistant, protective clothing, e.g.gloves.
To do this, proceed as follows:
1� Loosen the mounting nut(1) of the solenoid. To do this, turn the
mounting nut(1) one turn counterclockwise.
2� Turn the solenoid body(2) to the desired position.
3� Re-tighten the mounting nut. Tightening torque of the mounting nut: 5+1Nm
(width across flats SW26, 12kt DIN3124).
On axial piston units with aHirschmann connector according to
DINEN175 301-803-A/ISO4400, the following tightening torques apply when
mounting plug-in connectors:
• Mounting bolt M3(3): 0.5Nm
• Union nut M16×1.5(4): 1.5–2.5Nm

7�6 Performing flushing cycle
In order to remove foreign particles from the system, BoschRexroth recommends
aflushing cycle for the hydraulic system before the first commissioning. To avoid
internal contamination, do not include the axial piston unit in the flushing cycle.
Use an additional flushing unit to perform the flushing cycle. Follow the
instructions of the flushing unit's manufacturer for the exact procedure during
the flushing cycle.
