WARNING
Operating medium leaving/leaking out of the way valve may get in contac
with hot machine parts, posing a risk of fire.
The way valve is under pressure!
On operation with manual operation knob, uncontrolled piston rod movements
may result posing a risk to persons and property. This movement may pose a
risk to both individuals and objects.
During operation of the way valve, the output pressure may vary severely in
case of a failure of the electric energy or of malfunctions of the control
electronics integrated in the way valve. The piston rod of a hydraulic cylinder,
for example, may move uncontrolled posing a risk to persons or objects.
WARNING
The way valve is a hydraulic unit. In case of improper use, operating medium
being under pressure may leak out. The operating medium poses a risk to the
health and life of the operating staff. Prior to performing any work on the way
valve, switch off the hydraulic supply system.
In case of improper use, operating medium being under pressure may leak
out on the sealing surfaces.
On commissioning or operation of the way valve, spraying hydraulic oil ma
get into the eyes causing blindness. Wear safety goggles for all work
performed on the way valve.
During operation, the outer surfaces of the way valve and the hydraulic
connecting lines may become hot due to the operating medium. Any contac
may cause injuries by burning. Prior to performing any work on the way valve,
let the way valve cool down.
CAUTION
Prior to performing any work, switch off the hydraulic supply system.
On commissioning or operation of the way valve, the end of the piston rod
directly or indirectly driven by the way valve may move uncontrolled in case o
a failure of the hydraulic or electric energy, due to malfunctions in the maste
control or on the way valve. This movement may pose a risk to both
individuals and objects. Prior to performing any work on the way valve, switch
off the hydraulic and electric auxiliary energy.
