Penetrating water and humidity!
In case of use in humid or wet environments, water or humidity may penetrate
at electrical connections or the valve electronics. This may cause malfunctions
at the valve and unexpected movements in the hydraulic system, which may result
in personal injury and damage to property.
▶
Only use the valve within the intended IP protection class or lower.
▶
Ensure before the assembly that all seals are fitted and the electrical
connections are intact.
Hot surface!
Risk of burning!
▶
Provide for a suitable touch guard.
▶
During operation, only touch the valve using heat-protective gloves. Allow the
valve to cool down to room temperature before touching it directly with your
hands during maintenance work.
Contaminated hydraulic fluid!
Contamination in the hydraulic fluid may cause functional failures e.g. jamming or
blocking of nozzles of the valve. In the worst case, this may result in unexpected
system movements and thus constitute a risk of injury for persons.
▶
Ensure an adequate hydraulic fluid cleanliness according to the cleanliness
classes of the valve over the entire operating range.
Leakage in case of incorrect working temperatures!
The use of the valve outside the approved temperature ranges may lead to
permanent leakage at the valves. Thus, hydraulic fluid in the form of a leaking
hydraulic fluid jet may injure persons, lead to damage to property and endanger
the environment.
▶
Only use the valve within the intended environmental and hydraulic fluid
temperature range.
▶
In case of leakage, immediately exchange damaged seal rings or the valve.
Corrosion!
The valve described has surface protection (see "Data sheet "29583-XL"). If the
valve is used in a damp environment, the valve and the valve mounting screws may
corrode. This reduces the stability of the valve mounting screws so that the valve
may become loose and constitute a risk of injury.
▶
Exchange valves with corrosion damage at an early stage.
▶
Regularly check the surface protection on the valve and the valve mounting
screws.
