RE 92050-01-X-B1/2019.08.23, Axial piston variable pump A4VSO, BoschRexrothAG
The axial piston unit should be filled with a filling unit (10 µmfilter grade). Do not
operate the axial piston unit while it is being filled by the filling unit.
Only use hydraulic fluid incompliance with the datasheet (Part II):
The machine/system manufacturer can send you precise information about the
hydraulic fluid. Use a hydraulic fluid that corresponds to the data sheet (Part II).
At no point of the axial piston unit may the temperature of the hydraulic fluid be
higher than the temperature specified in the data sheet (Part II).
1. Place adrip tray under theaxial piston unit tocollect any hydraulic fluid that
mayleak.
NOTICE! Contaminated hydraulic fluid!
The cleanliness levels ofcommercial hydraulic fluids are usually insufficient for our
components.
▶ Use asuitable filter system tofilter hydraulic fluids during filling tominimize solid
particle contamination and water inthe hydraulic system.
▶ Note that contaminated hydraulic fluid can constitute a risk of sparking due to
overheating.
2. Fill and air bleed theaxial piston unit via theappropriate ports; see chapter7.3
"Installation position" onpage32. Also fill thehydraulic lines ofthesystem.
NOTICE! Risk ofproperty damage due toinadequate lubrication!
Product can bedamaged ordestroyed!
▶ When using a shut-off valve in the suction and/or drain line, make sure that the
input of the axial piston unit can only be started when the shut-off valves are
open.
3. When using a shut-off valve in the suction and/or drain line, only operate the axial
piston unit when the shut-off valves are open.
4. Test thedirection ofrotation ofthedrive motor. To do this, run thedrive motor
briefly atthelowest rotational speed (inching). Make sure that thedirection
ofrotation oftheaxial piston unit agrees with thedetails ofthename plate,
see chapter5.3 "Product identification", Fig. 3:Name plate A4VSO ATEX on
page 23.
5. Operate theaxial piston pump atalow rotational speed (starter speed for
internal combustion engines and/orinching mode for electric motors) until
thehydraulic system iscompletely filled and air bled. To inspect, drain the
hydraulic fluid at the drain port and wait until it drains without bubbles.
8.1.4 Testing thehydraulic fluid supply
The axial piston unit should always have asufficient supply ofhydraulic fluid.
For this reason, thesupply ofhydraulic fluid must beensured atthestart
ofthecommissioning process.
