3 General instructions on property
damage and product damage
The following information applies 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.
▶ Disconnect 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. Avoid air inclusions in the forward drive shaft
bearing, especially with the axial piston unit installed with the drive shaft
upward.
▶ Check the hydraulic fluid level in the housing area regularly and replenish,
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 boost line and suction line to the anti-cavitation valves are
always filled with hydraulic fluid during commissioning and operation.
▶ Ensure in case of above-reservoir installation that before initial start-up of the
axial piston pump (commissioning or recommissioning), the suction line to
the anti-cavitation valves is completely filled with hydraulic fluid. Make certain
that the axial piston pump does suck in hydraulic fluid and build up pressure
directly after start-up. In case of longer standstill period, suitable measures
have to be taken to prevent draining of the suction lines.
