3 General instructions on damage
to property and theproduct
The following instructions apply to chapters 6 to 14.
NOTICE
Danger from improper handling!
Product can get damaged!
▶ Do not expose the product to excessive mechanical loads.
▶ Never grab or climb onto the product.
▶ Do not place/lay any objects on the product.
▶ Do not strike the drive shaft of the axial piston unit.
▶ Do not set/place the axial piston unit on the drive shaft or assembled parts.
▶ Do not strike assembled parts (e.g. sensors or valves).
▶ Do not strike sealing surfaces (e.g. working ports).
▶ Leave the protective covers on the axial piston unit until you connect the lines.
▶ Disconnect all electrical connectors before electro-welding or painting
operations.
▶ Make certain that the electronic components (e.g.sensors) do not become
electrostatically charged (e.g.during painting operations).
Risk of property damage due to inadequate lubrication!
Product can get damaged or destroyed!
▶ Never operate the axial piston unit with insufficient hydraulic fluid. Specifically,
make sure that the rotary group has sufficient lubrication.
▶ When commissioning a machine/system, make sure that the housing area and
the working lines of the axial piston unit are filled with hydraulic fluid and
remain filled during operation. Air inclusions in the forward drive shaft bearing
are to be prevented, especially with the installation position “drive shaft
upwards”.
▶ Check the hydraulic fluid level in the housing area regularly; if necessary,
recommission. With above-reservoir installation, the housing area may drain
via the drain line after longer periods of disuse (air enters via the shaft seal)
or via the working line (gap leakage). This means the bearings are insufficiently
lubricated when the system is turned on.
▶ Make sure that the suction line is always filled with hydraulic fluid during
commissioning and operation.
Mixing of hydraulic fluids!
Product can get damaged!
▶ Before installation, remove all fluids from the axial piston unit to prevent mixing
with the hydraulic fluid used in the machine/system.
▶ Any mixing of hydraulic fluids from different manufacturers or different types
from the same manufacturer is generally not permitted.
