protective cover and mounting bolts
4 Transport protection for the through drive
Ports intended for connecting lines come with protective plugs and/or
threaded plugs, which serve as transport protection. All ports required
for the function must be connected (see Tabelle 25 to Tabelle 28
"Ports A10FZO, A10VZO, A10FZG and A10VZG" starting on page48). Failure
to do so could lead to malfunctions or damage. If aport is not being used, plug
it with athreaded plug since the protective plugs are not pressure-resistant.

NOTICE
Insufficient suction pressure!
Generally, aminimum permissible suction pressure at portS(A/B) is specified
for axial piston pumps in all installation positions. If the pressure at portS(A/B)
drops below the specified values, damage may occur which may lead to the
axial piston pump being damaged beyond repair!
▶ Make sure the required suction pressure is maintained. This is influenced by:
– The piping (e.g.suction cross-section, pipe diameter, length of suction line)
– The position of the reservoir
– The viscosity of the hydraulic fluid
– A filter element or check valve in the suction line (check the level of
contamination of the filter element regularly)
– The geodesic height of the place of use
CAUTION
Incorrectly connected suction and pressure lines!
Risk of injury and property damage!
▶ Make sure that the corresponding suction and pressure port is assigned to the
correct direction of rotation. Information on this can be found in data sheet
91485 and in Tabelle 7 to Tabelle 9 "Flow direction" starting on page24.
