notes on routing lines
Fig. 9: Removing transport protection
1 Protective covers
Ports intended for connecting lines are covered by protection plugs or threaded
plugs, which serve as transport protection. All ports required for functional
operation must be connected (see Table 10 "Ports A2FM/A2FE Series 70" on
page 33). Failure to comply with this could lead to malfunctions or damage. If a
port is not connected, it must be plugged with a threaded plug because
protection plugs are not pressure-resistant.
The following information only applies to fixed motors with pressure relief valve.
Setting screws are protected against unauthorized resetting by means of protection
caps. Removal of the protection caps will void the warranty. If you need to change
settings, contact your Bosch Rexroth service partner (for address, see Chapter 10.5
"Spare parts" on page 43).
7.4.8 Hydraulically connecting the axial piston unit
The machine/system manufacturer is responsible for dimensioning the lines. The
axial piston unit must be connected to the rest of the hydraulic system in accordance
with the hydraulic schematic of the machine/system manufacturer.
The ports and fastening threads are designed for the maximum pressure specified in
the data sheet. The machine/system manufacturer must ensure that the connecting
elements and lines correspond to the specified application conditions (pressure,
flow, hydraulic fluid, temperature) with the necessary safety factors.
Connect only hydraulic lines that are appropriate for the axial piston unit port
(pressure level, size, system of units).
Observe the following notes when routing the pressure and drain lines.
• Lines and hoses must be installed without pre-charge pressure, so that no further
mechanical forces are applied during operation that will reduce the service life of
the axial piston unit and, if applicable, the entire machine/system.
• Use suitable seals as sealing material.
• Pressure line:
– For the pressure lines, use only pipes, hoses and connecting elements rated for
the working pressure range specified in data sheet 91071 (see Table 10).
