3 General instructions onproperty
damage and product damage
The following instructions apply tochapters 6 to14.
NOTICE
Danger from improper handling!
Product can bedamaged!
▶ Do not subject theproduct toimproper mechanical loads.
▶ Never use theproduct ashandle orstep.
▶ Do not put/place any objects onthe product.
▶ Do not strike thedrive shaft oftheaxial piston unit.
▶ Do not set/place theaxial piston unit onthe drive shaft orassembled parts.
▶ Do not strike assembled parts (e.g. sensors orvalves).
▶ Do not hit sealing surfaces (e.g. onthe work connections).
▶ Leave theprotective covers onthe axial piston unit until you connect thelines.
▶ Disconnect all electrical connectors before arc welding andpainting operations.
▶ Ensure that theelectronic components (e.g. sensors) are not electro-statically
charged (e.g. during painting operations).
Risk ofproperty damage due toinadequate lubrication!
Product can bedamaged ordestroyed!
▶ Never operate the axial piston unit without sufficient hydraulic fluid.
Specifically,make sure that therotary group has sufficient lubrication.
▶ When commissioning amachine/system, make sure that thehousing area and
theworking lines oftheaxial piston unit are filled with hydraulic fluid and
remain filled during operation. Avoid air inclusions inthe forward drive shaft
bearing, especially with theaxial piston unit installed with thedrive shaft up.
▶ Check the hydraulic fluid level inthe housing area regularly and recommission,
ifnecessary. With above-reservoir installation, the housing area may drain
viathe drain line after longer standstill periods (air enters viathe shaft seal)
orviathe working line (gap leakage). This means the bearings are insufficiently
lubricated when the system isturned on.
▶ Make sure thesuction line isalways filled with hydraulic fluid during
commissioning and operation.
