installed. Contamination of the hydraulic fluid can considerably affect the
function and service life of the axial piston unit.
▶ When using pump carriers in combination with the "drive shaft upward"
installation position, dirt may accumulate on the shaft seal, which may lead to
leakage. In case of highly contaminated environmental conditions, any bleed
bores in the pump carrier should be closed, complying with applicable machine
safety standards. Apart from that, regular checks and/or cleaning is necessary.
Observe the information in chapter10.1 "Cleaning and care" on page58 and
Tabelle 30 "Inspection schedule" on page59.
▶ Use fiber-free cleaning cloth.
▶ Use suitable, mild cleaning agents to remove lubricants and other heavy
contamination. Do not allow cleaning agents to enter into the hydraulic system.
7�3 Installation position A10FZO, A10VZO
The following installation positions are permissible. The pipeline routing shown
illustrates the basic layout.
Port F
is part of the external piping and must be provided on the customer side
to make filling and air bleeding easier.
7�3�1 Below-reservoir installation (standard)
Below-reservoir installation means that the axial piston unit is installed outside of
the reservoir below the minimum fluid level.
Recommended installation position: 1.
Because complete air bleeding and filling is not possible in installation
positions 2 and 3, the pump must be air bled and filled in ahorizontal position
prior to installation.
