Safety instructions
Safety instructions
▶ During and shortly after operation, there is a risk of
burning on the axial piston unit. Take theappropriate
safety measures (e.g. bywearing protective clothing).
▶ Moving parts incontrol equipment (e.g. valve spools)
can, under certain circumstances, get stuck
inanundefined position duetocontamination
(e.g.impure hydraulic fluid, abrasion orresidual dirt
from components). Asaresult, the hydraulic fluid flow
and the build-up oftorque inthe axial piston unit can
nolonger respond correctly tothe operator’s
specifications. Even theuse ofvarious filter elements
(external orinternal flow filtration) will not rule out
afault but merely reduce therisk. The machine/system
manufacturer must test whether remedial measures are
needed onthe machine for the application concerned
inorder tobring the driven consumer into asafe
position (e.g. safe stop) and ensure any measures are
appropriately implemented.
