3 General instructions on property
damage and product damage
The following notices apply to chapters 6 to 14.
NOTICE
Danger from improper handling!
Product can be damaged!
▶ Do not subject the product to improper mechanical loads.
▶ Never use the product as handle or step.
▶ Do not put/place 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. solenoids or valves).
▶ Do not hit sealing surfaces (e.g. on the work connections).
▶ Leave the protective covers on the axial piston unit until you connect the lines.
▶ Diskonnect all electrical connectors before arc welding and painting operations.
▶ Make sure the electronic components (e.g. sensors) do not build up
electrostatic charges (e.g. during painting).
Risk of property damage due to inadequate lubrication!
Product can be 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 intrusions in the forward drive shaft bearing are to
be prevented, especially with the installation position "drive shaft upwards"
(if permissible).
▶ Check the hydraulic fluid level in the housing area regularly and recommission,
if necessary. For above-reservoir installation, the housing area may drain out
through the drain line after prolonged standstill periods (air enters through the
shaft seal) or through the working line (gap leakage). This means the bearings
are insufficiently lubricated when the system is turned on.
▶ Make sure the suction line is always filled with hydraulic fluid during
commissioning and operation.
▶ With above-reservoir installation, an axial piston unit must be moved to full
swivel angle after no more than three seconds during commissioning and
recommissioning. Make sure that the axial piston unit really does draw in
hydraulic fluid and build up pressure (for axial piston variable pumps in
open circuits).
