Bosch 70 Series - 8.3 Recommissioning After Standstill

Commissioning 39/52
RE 91071-01-B/03.2015, A2FM/A2FE Series 70, Bosch Rexroth AG
hydraulic efficiency increases as well through the conclusion of the running-in phase
of approx. 10 operating hours.
To ensure that contamination in the hydraulic system does not damage the axial
piston unit, Bosch Rexroth recommends the following procedure after the running-in
phase:
▶ After the running-in phase, have a hydraulic fluid sample analyzed for the required
cleanliness level.
▶ Change the hydraulic fluid if the required cleanliness level is not reached. If a
laboratory test is not carried out after the running-in phase, it is recommended to
change the hydraulic fluid.
8.3 Recommissioning after standstill
Depending on the installation conditions and ambient conditions, changes may occur
in the hydraulic system which make recommissioning necessary.
Among others, the following criteria may make recommissioning necessary:
• Air and/or water in the hydraulic system
• Old hydraulic fluid
• Other contamination
▶ Before recommissioning, proceed as described in Chapter8.1 “Initial
commissioning” on page36.
