3 General instructions on damage to
equipment and the product
The following instructions apply for 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 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.
▶ Ensure that theelectronic components (e.g. sensors) are not electro-statically
charged (e.g. during painting operations).
Risk ofproperty damage due toinadequate lubrication!
Product can bedamaged ordestroyed!
▶ Never operate theaxial piston unit with insufcient hydraulic uid.
Specically, make sure that therotary group has sufcient lubrication.
▶ When commissioning amachine/system, make sure that thehousing area and
theworking lines oftheaxial piston unit are lled with hydraulic uid and
remain lled during operation.
▶ Check thehydraulic uid 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 insufciently lubricated when thesystem isturned on.
▶ Make sure thesuction line isalways lled with hydraulic uid during
commissioning and operation.
Mixing hydraulic uids!
Product can bedamaged!
▶ Before installation, remove all uids from theaxial piston unit toprevent
mixing with thehydraulic uid used inthe machine/system.
▶ Any mixture ofhydraulic uids ofdifferent manufacturers and/or different
types ofthesame manufacturer isgenerally not permissible.
