Bosch Rexroth AG, A10VO, A10VSO Series 31, RE 92701-01-B/04.2018

prior to installation.

7.3.2 Inside-reservoir installation
NOTICE
Risk of damage with inside-reservoir installation!
To prevent damage to the axial piston unit, all plastic parts (e.g. protective plugs,
covers), except for the tamper-proof caps, must be removed prior to installation in
the reservoir.
▶ Remove all plastic parts, except for the tamper-proof caps, before you install the
axial piston unit in the reservoir. Make sure that no parts of them remain in the
reservoir.
▶ Remove the protective plug from the suction port S and open at least
one L port.
Inside-reservoir installation is when the axial piston unit is installed in the reservoir
below the minimum fluid level. The axial piston unit is completely below the
hydraulic fluid.
